I'm fascinated by the ecology of organisms from fetish porn. The idea of a terrestrial cephalopod that uses a host organism as an incubator is not actually that crazy, but it gets more fun the more seriously you take it.

Like yeah you specialize for hyperactive gonads and extremely survivable seminal fluid. But like, are you going for multiple host organisms? Or are you specializing specifically for humans? You probably want to shoot wide right? Just try to impregnate anything you see, and hope at least a handful of kids survive.

But uteruses are pretty chemically complex little organs. Even a slight change in the PH balance could send your host into sepsis or shock or whatever.

And what do you EAT? like how do these organisms actually survive? When they're not banging are they squirming around eating snails like aquatic cephalopods? They're usually depicted as pretty big too, usually strong enough to lift a fully grown human off the ground with what have to be like, hydrostatic appendages? That's a much more energy-intensive physiology to have on land.

They're clearly not specialized for hunting. But what food source could support an organism at this size? Those tentacles could probably be useful for navigating like, mangrove swamp type areas with abundant foliage and lots of little cracks to navigate. Maybe they're kinda like barnacles, or some kinda terrestrial coral. They just kinda plant themselves in a nutrient-rich stream and just kinda impregnate anything that brushes past them like some kinda parasitic sex anemone.

Electrolytes and why they're important especially when water f4st!ng:

Electrolytes are electrically charged minerals, such as sodium, potassium, calcium, magnesium, chloride, bicarbonate, and phosphate. They are involved in various physiological processes.

During a water f4st, the body can lose electrolytes through various means, such as urine, sweat, and even through breathing.

Without sufficient intake of electrolytes, the body may experience imbalances that can lead to various health issues including:

muscle cramps, dizziness, weakness, irregular heartbeats, and in severe cases, even life-threatening conditions such as de4th.

Here's a breakdown of each electrolyte and its role in the body:

Sodium (Na+):

Role: Sodium is the primary extracellular cation (positively charged ion) and plays a vital role in maintaining fluid balance and blood pressure. It is essential for nerve impulse transmission and muscle function.

Source: Commonly found in table salt (sodium chloride) and many processed foods.

Potassium (K+):

Role: Potassium is the primary intracellular cation. It helps regulate fluid balance, nerve impulses, muscle contractions (including the heart), and maintains proper cellular function.

Source: Found in various fruits and vegetables, such as bananas, oranges, potatoes, and spinach.

Calcium (Ca2+):

Role: Calcium is essential for maintaining strong bones and teeth. It also plays a key role in muscle contractions, nerve transmission, blood clotting, and cell signaling.

Source: Dairy products, leafy greens, nuts, and fortified non-dairy milk.

Magnesium (Mg2+):

Role: Magnesium is involved in hundreds of enzymatic reactions in the body, including energy production, protein synthesis, muscle and nerve function, and maintaining healthy bones.

Source: Found in nuts, seeds, whole grains, leafy greens, and legumes.

Chloride (Cl-):

Role: Chloride is the major extracellular anion (negatively charged ion) and works closely with sodium to help maintain fluid balance and osmotic pressure in cells.

Source: Commonly found in table salt (sodium chloride) and many processed foods.

Bicarbonate (HCO3-):

Role: Bicarbonate is involved in regulating the body's acid-base balance (pH level) and is a crucial component of the bicarbonate buffering system.

Source: The body produces bicarbonate as part of normal metabolic processes.

Phosphate (HPO42-):

Role: Phosphate is essential for bone and teeth mineralization, energy production (adenosine triphosphate, ATP), and serves as a component of DNA and RNA.

Source: Found in various foods, including meat, dairy products, nuts, and whole grains.

To prevent these complications and support the body during a water f4st, it is crucial to supplement with electrolytes.

Many people who practice prolonged water f4st!ng or intermittent f4st!ng find it helpful to take electrolyte supplements or consume electrolyte-rich drinks to ensure they maintain proper mineral balance throughout the f4!sting period. However, it is essential to consult with a healthcare professional before starting any regimen or supplement routine, as individual needs may vary.

Exploring the Intricacies of the Respiratory System 🫁💨

Welcome to my Tumblr blog, where we embark on an exciting journey through the intricate world of human anatomy and physiology. Today, we're focusing our lens on the respiratory system – a wondrous network of organs and tissues that orchestrates the exchange of gases essential for our survival. So, fasten your seatbelts as we venture into the fascinating realm of respiration!

Anatomy of the Respiratory System: A Symphony of Structures

At its core, the respiratory system consists of a highly organized ensemble of organs and structures working together seamlessly. This symphony of components includes the nose, pharynx, larynx, trachea, bronchi, and, of course, the lungs. Each of these elements has a crucial role to play in the intricate process of breathing, ensuring our bodies receive a constant supply of life-sustaining oxygen while effectively eliminating carbon dioxide.

The Alveoli: Tiny Powerhouses of Gas Exchange

Now, let's zoom in on the alveoli, the star players in the respiratory system's performance. These microscopic air sacs, nestled deep within the lungs, are where the real magic happens. Through the process of diffusion, oxygen from inhaled air enters the bloodstream, while carbon dioxide, a waste product of metabolism, is expelled from the blood into the alveoli to be exhaled. It's here, at this cellular level, that the respiratory system's vital exchange takes place.

Breathing Mechanics: The Art of Inhalation and Exhalation

But how does it all come together? Breathing, a seemingly simple act, is a complex process guided by the contraction and relaxation of specialized muscles, primarily the diaphragm and intercostal muscles. These muscular movements manipulate the volume of the thoracic cavity, creating changes in pressure that facilitate the flow of air in and out of the lungs. Understanding the mechanics of breathing is fundamental to comprehending various respiratory disorders and their potential treatments.

Regulation of Respiration: A Symphony Conducted by the Brain

The respiratory system doesn't operate in isolation; it's under the watchful eye of our central nervous system. The medulla and pons, two regions of the brainstem, serve as the conductors in this symphony of breath. They continuously monitor factors like blood pH, carbon dioxide levels, and oxygen levels, adjusting our breathing rate and depth to maintain the delicate balance required for optimal body function.

Recommended Resources to Dive Deeper:

Book: "Principles of Anatomy and Physiology" by Gerard J. Tortora and Bryan H. Derrickson - This comprehensive textbook provides an in-depth exploration of the respiratory system, complete with detailed illustrations and accessible explanations for all levels of learners.

Don't you think it's unhealthy to puy perfume in someone's vagina? Asking after reading Dany's chapters.

I don’t have nearly as much experience with them as I’d like, but from what I’ve read, vaginas have an entire bacterial ecosystem that makes it self cleaning, and putting anything in it (soaps, perfumes, oils) can cause irritation at best and disrupt vaginal pH and lead to endocrine issues at worst. We see Dány get dabbed inside twice with spiceflower and cinnamon perfumes, and cinnamon is alkaline, meaning it’s messing with her normally acidic vaginal pH (spiceflower is fictional, but from the way it’s described it seems to produce a burning sensation). It seems to be unhealthy to put this type of perfume in a vagina, however, Dány was shown to breastfeed 3 baby dragons, so clearly her physiology is an outlier in some regards, and so may be here. But if you consider the perfume, eating an entire raw horse heart, and being 14 coming from a family with hereditary health issues, the question stops being “Did Mirri kill Rhaego?” and becomes “What wasn’t going to kill Rhaego?”

🤔💪 Do Gallifreyans experience lactic acid build-up?

Ever wondered if Gallifreyans hit the gym? Who knows, but their physiology sidesteps the usual post-exercise aches, making lactic acid build-up, a common human issue, practically non-existent for them.

Advanced Respiration: Their lungs are not only high-performance but are supported by an independent respiratory network. This efficient oxygen supply keeps their muscles from accumulating lactic acid.

Efficient Energy Use: They rarely switch to anaerobic respiration - the process that in humans leads to lactic acid accumulation. Their cells are all about energy efficiency.

Muscle Composition: Gallifreyan muscles definitely aren't superhuman, but they're loaded with slow-twitch fibres, optimising them for endurance.

Stellar Acid-Base Balance: Their natural ability to maintain optimal body pH means there's no environment for lactic acid to thrive.

Gallifreyans are biologically built for the long haul without the usual post-exercise "ouch" moments as easily as humans. Maybe don't engage in a competitive marathon with them.

Even when the pH of the medium is kept neutral, most plants grow better if they have access to both NH4+ and NO3- because absorption and assimilation of the two nitrogen forms promotes inorganic cation-anion balance in the plant.

general society is such an underthought aspect of mha. obviously there’s the big things like the obsession over heroic quirks and the demonisation of villainous quirks. quirkless people are dismissed entirely but i don’t think we talk about how society in general would have to handle a world with super powers.

we know after afo’s first uprising, the government overcorrected and outlawed public quirk usage. we know people have their quirks registered and go through quirk counselling as well as a type of gym class where they practice under teacher supervision.

how in the hell is that supposed to work?

the closest equivalent i can think of is mental health services. someone would have to study for a long time to be able to pursue quirk counselling as a career. it’s also a highly personalised system: everyone has a different quirk - even similar ones have different activations, triggers, exceptions and drawbacks - so no two sessions could ever be the same. if anyone’s been through mental health services, you know how rough it is; it’s an overworked, underpaid system and if you live somewhere that only offers a few free visits, it can also be expensive.

and that’s an elective service.

almost everyone on the planet would need quirk counselling.

there’s no way they could implement such a labour intensive and individual public system and we literally see that they can’t.

we see the gym class in amajiki’s flashback and he only has a few minutes with his teacher before he’s chided for not being more impressive and utilising his quirk to the fullest and they move on to the next student. say a standard class is twenty students like it is at ua. that leaves just over two minutes for each student to learn and practice their quirks. you can’t focus on just one kid per lesson bc what will the other nineteen do? do teachers also have to have a degree in quirk counselling? is that part of becoming a phys ed teacher or is it some random joe schmo trying to wrap his head around literal super powers?

given that inko goes to garaki - a doctor - to confirm izuku’s quirklessness, it can be assumed that quirk counselling is entwined with the medical system. i don’t know if you’ve ever had to apply for a specialist before but you can be on their waiting list for a while. a quirk counsellor is essentially a specialist. are there subcategories of counsellors? do you focus on either emitter, transformation or mutation the way doctors become cardiologists, paediatricians and neurologists? or is one person expected to be equally knowledgeable about all three?

we see through toga that her counsellor identified her need for blood but they didn’t find a way to curb those instincts or even find a supplement for her. she’s left to be abused by her family for something she can’t control bc it’s literally in her dna. compare that to iida who knows he needs orange juice to power his quirk. his entire family are pro heroes so it would be easy to assume they could employ a private quirk counsellor the same way richer people can employ private doctors.

how many people have specific requirements due to their quirks? changes in their physiology that have to be treated the same way nutritional deficiencies and allergies do? even people without mutations probably have those requirements: does kirishima’s shark teeth mean he’s an obligate carnivore? does mina’s acid change her ph levels and what vitamins and minerals she needs? how would they figure that out? quirk counselling.

what about kids like touya who would need extensive counselling so he could figure out how to live with his quirk without hurting himself? kaminari essentially has seizures and they’re so normal to him and everyone around him that they’re the butt of jokes. they wouldn’t be a one and done patient; there’s always going to be people that need continued support the exact same way there’s people that need developmental and disability support. there would be so many quirks that harm their user, are they just taught to bury their quirks? as if that wouldn’t cause any physical or mental consequences?

governments can’t create a system that applies to only some people, we’re expected to believe they’ve made one that applies to all of them?

#bnha #my hero academia #mha meta #i imagine its similar to therapy in that the first session would be free since its probably required in order to register a child’s quirk #they probably figure out activation in that time and thats it #onto the next kid bc there will always be another kid #you want more information on your child’s power? you better be able to pay for more sessions #even quirkless people need to be fully assessed to ensure theyre quirkless #i doubt anyone else is as interested in this as i am but it feels like just another world building aspect horikoshi just kinda skipped #quirk counselling is just sort of thrown in with toga and curious and it becomes just another concept that is brought up and discarded #quirk counselling quirklessness mutant prejudice the quirk singularity theory general mutations outside of mutant quirks #theres so many little interesting concepts that are never given the development they deserve #and when they are like in the last few chapters its done in such a shallow handwavy way that i wish hed just leave them alone altogether #no wonder the plf exists quirks are so suppressed in society while also being a status symbol #and yet its a completely hypothetical advantage if they dont become a hero or a villain #if a kid has a heroic quirk theyre held on a pedestal and if they have a villainous one theyre demonised at best and abused at worst #koichi was almost given a fine bc he was using his quirk to get through foot traffic quicker how is there not a riot every year about #quirk freedom and rights violations? #and yet its completely glossed over #go beyond plus ultra #coming out of my cage and ive been doing just fine.txt

10 Ways to Improve Your Microbiomes in 2023✨

Yes, I meant to say microbiomes with an S✨

💚Microbiome Health (ie. Gut Health, Skin Health, Oral Health, Mental Health, Emotional Health, Nervous System Regulation, etc) is a major facet of Holistic Health because human beings intrinsically live intertwined with microbes. They are our symbiotic buddies, which means that our lifestyles are interdependent. If you're not thriving, neither are they. Self-care is not at all selfish, because it's always influencing at least millions of these tiny creatures💚

1✨ Eat a diversity of whole plant foods (extra points if you get a lot of fresh ones in your belly).

2✨ Establish high standards for rest for your lifestyle. Live more slowly. Stop the worrying (it's not necessary nor is it useful!). Meditate deeply. And focus on getting rejuvenated from your sleep. I recommend herbal adaptogens & relaxing nervines to learn more how relaxation feels on a physiological level.

3✨ Leave off or reduce products with synthetic ingredients in your life where you can. They tend to have a pH which is unsupportive to certain microbes or not "play nice" with certain populations.

4✨ Get probiotics in your diet. Condiments like ketchup, mustard, and soy sauce were always probiotic before these extremely shelf-stable versions. You can DIY those. Or kimchi, sauerkraut, miso, natto, yogurts, kombucha, drinking vinegars/shrubs, fermented bean pastes, poi, ginger bugs, coconut water kefir, and so many more. Every culture has their own. Probiotic foods are a great way to get more connected to your ancestral lines & explore other cultures.

5✨ Incorporate more herbs into your life. Many are digestion-supportive, gut-building, prebiotic, cell-regenerative, tissue-moistening, wound-healing, etc.

For the rest of the tips & elaboration on the tips, see the Patreon post scheduled to post @ 8pm EST today Jan 2nd 2023 for the Healing Babes Tier+!

May all beings be blissful 💚

Exploring the Marvels of Biological Macromolecules: The Molecular Machinery of Life (Part 2)

Amino Acids: The Building Blocks

Proteins are composed of amino acids and organic molecules that contain an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a distinctive side chain (R group). There are 20 different amino acids, each with a unique side chain that confers specific properties to the amino acid.

Primary Structure: Amino Acid Sequence

The primary structure of a protein refers to the linear sequence of amino acids in the polypeptide chain. The genetic information in DNA encodes the precise arrangement of amino acids.

Secondary Structure: Folding Patterns

Proteins don't remain linear; they fold into specific three-dimensional shapes. Secondary structures, such as α-helices and β-sheets, result from hydrogen bonding between nearby amino acids along the polypeptide chain.

Tertiary Structure: Spatial Arrangement

The tertiary structure is the overall three-dimensional shape of a protein, determined by interactions between amino acid side chains. These interactions include hydrogen bonds, disulfide bridges, ionic bonds, and hydrophobic interactions.

Quaternary Structure: Multiple Polypeptide Chains

Some proteins, known as quaternary structures, comprise multiple polypeptide chains. These subunits come together to form a functional protein complex. Hemoglobin, with its four subunits, is an example.

Protein Functions: Diverse and Essential

Proteins are involved in an astounding array of functions:

Enzymes: Proteins catalyze chemical reactions, increasing the speed at which reactions occur.

Structural Proteins: Proteins like collagen provide structural support to tissues and cells.

Transport Proteins: Hemoglobin transports oxygen in red blood cells, and membrane transport proteins move molecules across cell membranes.

Hormones: Hormonal proteins, such as insulin, regulate various physiological processes.

Immune Function: Antibodies are proteins that play a crucial role in the immune system's defense against pathogens.

Signaling: Proteins are critical in cell signaling pathways, transmitting information within cells.

Protein Denaturation and Folding

Proteins are exquisitely sensitive to environmental changes. Factors like pH, temperature, and chemical agents can disrupt protein structure, leading to denaturation. Proteins can sometimes refold into their functional shape if conditions return to normal.

Protein Diversity

The vast diversity of proteins arises from the combinatorial possibilities of amino acid sequences, secondary structure arrangements, and three-dimensional conformations.

Proteins, the versatile and intricate macromolecules, are the workhorses of biological systems. These molecules, comprised of chains of amino acids, are central to nearly every aspect of life, orchestrating various functions, from catalyzing chemical reactions to providing structural support. Let's delve into the remarkable world of proteins.

Virginia Goats Rue,

Tephrosia virginiana

Whenever I see this plant I think acidic nutrient poor soils, ericaceous.

It prefers acidic weathering sand, well drained, in full sun, and often is associated with heavily mycorrhizal dependent environments despite not associating with mycorrhizae. It’s extremely good at nitrogen fixation and cannot take being shaded out. Sandy oak savanna, pine barrens, riolitic gravel barrens, dry prairie with an associated circum acidic ph are ideal locations for this species. Here, at RRG, we see it on a burn ridge, specifically in MG FE rich acidic sandstone in what is classified as an ericaceous heath belt. It is not a forbe despite it’s looks but has a woody basal crown and a very stout woody tap root that branches scarcely into tenuous  fibrous roots with root nodules for the nitrogen fixing bacterial units. Some claim that this physiological trait is a caudex or a caudiform structure, though it’s more knobby and less of a thickened mass/base that hasn’t been fully investigated for water storage, instead I think that it’s maybe more likely to produce herbaceous epicormic shoots as a reaction to fire and may more likely be a lignotuber(post fire regenerative woody knobby base) instead of a caudex; either way, this woody habit makes this species a sub shrub and not a forbe. Animals are not likely to graze/ browse on this legume due to slight toxicity; with this said, the rotenone compound is a known icthyotoxic chemical (lethal to fish if made into root powder and used.) While no longer used for fishing due to knowledge of bio-accumulation of toxins, it is being researched for invasive species control. The species reminds me of partridge pea in it’s ground bird dispersed seeds, while we have a true  Faboideae sect. species with banner and keel morphology, you’ll notice that it has an exposed/ keel and wing form allowing easy access and buzz pollination more often than most papillionaceous flowers. (senna and partridge peas are primarily buzz pollinated and are in sect. Caesalpinioideae (subfamily of fabaceae)). I see more bumble bees and wasps on this species than any other forbe this time of year ( Late May). 

Most Tephrosia are coastal plains species with only one other “wide spread” species (T. spicata)

Though T. onobrychoides does make it in-land due to Oklahoma short grass prairie matrix.
