Excretory System of Human

Excretory System of Human Excretory System of Human Excretory System – The Metabolism Of Carbohydrates And Fats In The Body Produces Carbon Dioxide And Water Vapour. Excretory Substances Such As Nitrogen Are Formed From The Metabolism Of Proteins. For Example, Ammonia, Urea And Uric Acid. Excretory Substances Such As Carbon Dioxide Are Removed From The Body Through The Lungs. Excretory…

EXCRETORY SYSTEM OVERVIEW -MYA CARE

The excretory system is crucial for the survival of an organism, ensuring that all functions of the body are carried out effectively and efficiently. This system is primarily involved in the removal of waste products from the body. Without it, the body would become highly toxic and quickly succumb to a lethal disposition.

Yes Touma Akechi. Sorry I've neglected you for like 8 months Touma Akechi. I love you Touma Akechi.

I need more info in the freakvamp au. like. does akito have organs? if not, does that include a brain?if n brain, how think? if have, why? if no blood, there's no way to get water around his body? no blood vessels? so uselessly existent organs??????? HELP

HAHSGS SORRY OP I THOUGHT IT FITS HIS CURIOSITY

but to answer ur question, kinda! he only have those that's beneficial to his daily activity, like his digestive and respiratory system. for example he doesn't have a heart to pump blood because he has no blood to begin with.

the way it works is that akito only digest meat (carnivore moment) and the nutrients from said meat (extracted thanks to the help of his special digestive system) helps his internal organs work just like normal, even better if the meat is fresh + has blood on them. more nutrients means an even stronger body

and for the brains and other parts of the organs, it's really just.. pure meat slob no bones whatsoever (this might make people believe he's weak in general because of no skeletal structure underneath him but his muscle power are way beyond comprehension to balance it out) (he's still an anomaly afterall, he can't be easy to kill)

i didn't actually plan for this au to become a real big thing in this account so i haven't done much research BUT! here's what i think about it so far :3c

[44-moved-44]

This week on Soul/Cameron learning id biology (the hard way): acid blood

So, literally just after creating the post about id biology, other owner of the AU and I came up with ids having acidic blood that essentially digests anything it touches and magically gives the id sustenance.

Why does this happen? Well, ids don't have excretory systems nor intestines; the food/drink is partially digested in the stomach, then fully "absorbed" by the blood, which is in and of itself extremely corrosive. How do they get sustenance from something no longer in their body? Why, magic, duh!

Once the food itself is completely destroyed by the blood, the blood is removed through "bleeding", as Heart and Mind call it, in which they essentially cut open apart of their body and allow it to bleed, which is completely harmless and helps prevent an abundance of useless life force.

They also are capable of only surviving off oxygen, water, or food, however require much more of it in order to only subsist off of one of those alone. This is much more easily done by only subsisting off of two of them, but requires more of them.

Anyway, that's today's episode of "how far from a human can AXYER make a human character?" Stay tuned when I inevitably get to sticks.

Sorry, but this whole thing about the dice roll to convince Astarion not to ascend—let’s break it down.

The dice roll exists because Astarion is intoxicated—by blood, by fear, by power. Power is the only thing he thinks can set him free, but only because his perspective is painfully limited. The Insight check isn’t there by accident; it’s meant to give the player context. Astarion isn’t thinking clearly—not enough to truly reason.

Do you know what real fear does? It shuts down higher cognitive processes. The sympathetic nervous system takes over, triggering fight, flight, freeze, or fawn responses. Blood rushes to the muscles, the heart, the lungs, preparing the body to react quickly in case of danger. But at the same time, other functions that aren’t immediately useful—like digestion, excretory system, sexual function, and, yes, logical reasoning—get suppressed. It’s a matter of priorities—survival over everything else.

For example, studies show that reprimanding a child too harshly—scaring them—actually inhibits learning, making it completely counterproductive.

And in that moment, Astarion is like someone standing on the edge of a rooftop, ready to jump—not because he wants to die, but because he sees no other way out of his pain. And Tav/Durge is the damn firefighter or cop trying to talk him down before he hits the pavement.

And honestly—who here hasn’t had a conversation with a parent, a friend, or a teacher, only to later think, Shit, they were right, I was about to do something really stupid?

It’s not coercion, people. It’s just pointing things out. And the dice roll is there to break through all the things clouding Astarion’s mind—blood, fear, and everything in between. Not to convince him.

At this point in the adventure, Astarion is perfectly capable of making his own choices, and if he's deprived of that choice, he gets so furious that he attacks the player. In fact, if you categorically decide for him—either by refusing to help him or by interrupting the ritual—things end badly. He is the one who has to decide what to do, not the player.

It's no coincidence that Astarion gives his approval at the moment he realizes what it truly means to ascend and abandons the ritual. There's no lie there; we don't forget that approval. Just as it's no accident that, in the cemetery scene, Astarion says he feels seen by the player. Because yes—beyond the illusory veil of a sexy, evil vampire, we've seen through it and witnessed something else. We've seen the goodness within him.

Please, let's stop saying that Astarion wants to ascend at all costs and that he's forced not to do it. Otherwise, the reading of the game's and the character's subtext is completely lost. And note that this doesn't mean he doesn't also have the potential for evil.

It's exactly these internal contradictions—this constant oscillation between good and evil—that make him such a deep, well-rounded, and wonderful character. Please, let's not simplify him; that would be a crime.

"Harmony in body, mind & spirit"

Namaste people! Brown here again , you must be wondering why am I making post on ayurevda- the science of life or the oldest healing methods ? Well perhaps to add more knowledge which is pratical , simple, helpful and best . As a healer myself I emphasis on self-healing through energy but alas many people don't know the deeper aspects and meaning of energy that flows within them hence allow me to connect with your innate human biological features or functions and give you the ways to build life long happiness and holistic well-being.

NOTE : This is for educational purpose only , I'm no professional in this field.

समदोषः समाग्निश्च समधातु मलक्रियाः | प्रसन्नात्मेन्द्रियमनः स्वस्थ इत्यभिधीयते|

When the doshas are balanced, the digestive fire is equal, the tissues are in equilibrium, and the excretory functions are regular; when the mind, senses, and self are happy, that is called health.

⋆˚𝜗𝜚˚⋆۶ৎ⋆˚𝜗𝜚˚⋆୨ৎ⋆˚𝜗𝜚˚⋆

LEARNING - OBJECTIVES : Introduction to ayurevda, the three elements (dosh) of the body - their importance in our holistic well-being & relation with psychology - know which category you fall in personality wise .

WHAT IS AYURVEDA ?

Ayurveda is an ancient Indian system of medicine with a history spanning over 5,000 years. It's a holistic approach to health and well-being, focusing on balancing the body, mind, and spirit to prevent and treat diseases. The term "Ayurveda" means "knowledge of life" or "the science of life". It considers the individual as a whole, taking into account their physical, mental, and spiritual aspects. The diet and lifestyle is very intrisinc to it. The "father of Ayurveda" is widely regarded as Charak - who wrote charak-samhita . It came in first millennium BCE , this knowledge was transmitted from gods to sages than to the human physicians which came to be printed in sushruta-samhita - frame work of bharatiya or Hindu diety of Ayurveda ; Dhanvantri , who recarinated as king divodas to give this knowledge .

WHAT ARE TRI-DOSH ?

In a human body, there are three dosh or the three elements (vatt , pitah, kapha) which are the combination of (space , air, water and earth)

Here is the detailed explanation and importance of each dosh :

ᯓ VATTA :

▪︎ It associated with your cognition and movement composed of space and air which governs your blinking, muscle and tissue movements , pulsation of heart , movements in cytoplasm and cell-membrane . It is responsible or the indicator of life in your body . It's made of space and air.

▪︎ when it is is balanced It promotes to flexibility and creativity , makes a person confident and sharp-minded .

▪︎ it's disbalance leads to nervousness, anxiety, panic, excessive thinking, disturbed sleep, dry or chapped skin, constipation, gas, bloating, hard stools, low body weight, and sensitivity to cold and wind.

ᯓ PITTAH

▪︎ It is associated with your metabolism, body temperature, assimilation , nutrition and digestion. It is made of fire and water .

▪︎ When it is balanced It promotes understanding, intelligence, balanced nature in a person which allows one to connect with other properly or we say socialising.

▪︎ when it's in disbalance it would lead to indigestion , poor assimilation, aggression , jealously and poor disbalance of nature in a person .

ᯓ KAPAH

▪︎ It's associated with your body structure, bones , muscles and tendons keeping them together by providing a glue to it. It's made of earth and water .

▪︎ A good moisturized skin is the result of good amount of kapah in body. The kapah gives water to other parts of the body keeping them alive and in a well state . It's balance leads a person to have good emotional intelligence - understanding else , love and having compassion , calmness and forgiveness .

▪︎ It's disbalance leads to materialism , greed and envy . The one feels unsatisfied and unfulfilled with themselves and their life.

The following information has been taken from various references with mix of my own explanation which will further share later .

bugs molt internal organ lining??? how does that work; they don't have the same firm lining as a bug exterior, right? where does the lining like, go, does it get re absorbed into the body or shuttled into the excretory system or. my whole world is rocked by this rn

not like their entire digestive tract, but the upper parts of it, plus the lining of their spiracles (breathing tubes)—basically any part of the exoskeleton, including the parts where the exoskeleton goes inside the body (think of the inside of your mouth—it’s skin, more or less).

for the spiracles, it’s got to be pulled out, so every time you see cicada shells (the most easily spotted exuviae, in the NE USA) and you see the little white strings, that’s the lining of the tracheae. that’s another reason why molting is so dangerous: if it happens incorrectly then an arthropod cannot eat or cannot breathe.

BOFURIN BOYS AS BFS (PART 1 ?) ✨️

ft: Haruka Sakura , Hayato Suo , Akihiko Nirei.

a/n : art credits unknown. in cheers of the 2nd season starting , i wanted to write something for ma handsome fighters. ❤️‍🔥

Haruka Sakura

This boy will combust if you ever so much as breathe in the same direction as him , let alone being friends AND dating on top of that. Come on , we are talking about a guy who blushes at the thought of sbd ELSE having a gf , let alone himself...

If you are a type of person who likes teasing their partner, dating him would be a HEAVEN. This guy is a blushy mess and his face is so expressive that you would THRIVE on his embarrassed adorable reactions.

Awkward as hell when it comes to physical affection , will stand there like a stick if you hug him and don't expect him to ever return it . You will be the one to initiate things in the relationship until he gets comfortable, which is like a few years...

His love language is definitely acts of service. This man has climbed onto top of buildings like a goddamn ninja only to catch a cat. So for his gf , he would move mountains and order clouds around. But he turns beet red and denies it with his life when you point out sth that he did for you. "Baby , did you go there to bring me this water bottle ? Thank uu! How thoughtful of you..." "AS IF! I was just going into the kitchen and brought it back just because..."

Words of affirmation is something that he tries if you are into them. This guy has a hard time with verbal explanations and even normal conversations so you can't expect him to go full out complimenting you. The most you can get is a mumbled "it looks good on you" or "you did well" , but he tries i promise.

Same goes for gift giving , he tries if you are into it. But let's be real , this guy is an orphan with parents nowhere to be found. So his gifts would be more handmade and heartfelt and less things that he would spend money on. He would pick flowers and make a crown for you or make origami bracelets etc.

Is insecure of his appearance due to his past so please compliment him often.

Takes you out on picnic dates with homemade food or just stays in and spends time with you indoors as a date.

Your bodyguard on duty 24/7. Gets physical IMMEDIATELY when sbd looks at you in the wrong way and doesn't calm down until you either drag him tf outta there or coax him to relax by saying things like "its okay , it wasn't disturbing me".

Doesn't tell his friends about you until you are very into relationship , probably at least one year , because my poor boy will have a cardiac arrest at the single bit of their relentless teasing. But if you insist, he introduces you to them. (and probably goes to hide in the home for the next week)

If you ever to see him fight , he acts depending on your reactions. If you are scared after seeing him beat sbd half to death and want to stay away for a while , he gets upset a lot but respects it and keeps a safe distance. If you aren't scared and are like "wow , shit was cool" , he blushes at the praise. Later on , he insists on teaching you how to fight so you can defend yourself when he isn't around.

Hayato Suo

Speaking of diet , he would be against you eating outside. Instead he cooks himself and eats healthily at home with you and drinks a lot of tea. Makes you drink too.This man probably has a spare cooking book only for teas. Has a tea recipe suitable for every single occasion on earth. You caught cold ? Mint and limon tea coming up. You have bronchitis or cough ? Mulberry tea right on your table. You feel like your body odor has gotten bad lately ? Jasmine and rose tea one cup right in your hands. You having trouble with your excretory system ? Onion tea is brewing right on your stovetop.

Walking epitome of discipline. You need to study ? Under his supervision , you get straight A+'s. You need to keep your sleep routine going ? Will gently force you to bed , not physically but verbally. Your eyebags ? Gone , wtf is that ? Wanna go on a diet ? You are losing 15 pounds in a month with him.

This man is a MASTER of mixing praise with teasing , combined with that stupidly attractive half-smirk of his. Leaving you a blushing mess , running away from him because he is RELENTLESS at it. You can't even answer him because he finds another thing in your answer that he can tease you about.

Even as his gf , don't expect to see what is underneath that eyepatch. You probably won't even see him losing composure. Mans wakes up before you so you don't see his bed hair or smell his morning breath. (he probably doesn't have any but yeah...)

He will fight for you if sbd disturbs you without breaking a sweat and casually walks off like nothing happened , leaving that person not only beaten to a pulp but also humiliated as hell.

And then proceeds to hold the doors open for you or carry your purse like a gentleman , as if he didn't ruin sbd's dignity and threw into hell's pit. He is a gentleman at heart but can't help himself sometimes , no one messes with his girl.

He acts on every single one of them but his most dominant love language is words of affirmation imo. He would complement you like he is a walking poetry library. "You look as beautiful as a Lana Del Rey song" , "Does it feel heavy to carry constellations in your eyes ?".

He has a generally calming and safe presence so it makes it easy for you to open up to him or go to his arms to cry.

He is into calm-romantic dates and Chinese culture. So a date at a traditional restaurant with candle ambiances and traditional food while sitting over tatamis is his ideal perfect date.

Akihiko Nirei

This man is the no1 social butterfly you know. Like he is the definition of "a guy who knows a guy" but in a good way. He is so bubbly , energetic and friendly that people constantly get drawn into him. So he knows almost everyone throughout his hometown , thus has some INSANE connections to people you can't even imagine meeting. He is all like "so you need sbd who can extract oxyn hormone from a flower petal ? lemme see , i have a friend who works at a lab-..." type of bf.

Him being a social butterfly always contributes positively to you , even tho you may be a shy person. If you are an extrovert and actually like to engage with people-activities , he is the right gate that you can network with people through. And if you aren't a social person like him , having him beside you still ends up in your favor because he does all the talking and interacting so that you can stay in your comfort bubble.

We all know how he writes down info about all the fighters we have met throughout the series ? He has a spare notebook just for you. He keeps everything he learns about you in that book , written down in detail. And if you ever were to find out he blushes but still confidently and playfully brags about it to you and says sth along the lines of "see , i am an attentive bf."

He isn't a good fighter , despite being in an environment that constantly needs that talent. So he beats himself up on that and needs reassuring that he isn't worthless or weak. Please give him the biggest bear hug you can muster along with love-full smoochies.

Dates with him consist mostly of fun activities like amusement parks , animal cafes etc. But he is down for anything you wanna try and/or anywhere you wanna go spesifically.

i tried to create the anatomy of an irken [dis is a man] >:Ddd

I didn't find many canonical sources, so I did almost everything from scratch, based on human and insect anatomy

I am not a biologist, so there may be errors here, as I have only researched the subject superficially. However, this image is based on text rather than visualisation. It is just an anatomical atlas that I created for myself, in case I want to draw blood.

this is not the actual colour of the organs, i coloured them to make them easier to distinguish

ua/eng text below

1. легені - не таки масивні як у людей. частину функцій дихальної системи бере на себе покривна (шкіра) [див додаток "а"]

2. печінка селезінка одним органом [див додаток "б"]

3. стравохід

4. шлунок [див додаток "в"]

5. кишківнік [див додаток "г"]

6. нирки - за основу взяті мальпігієві судини, відповідають за видільну систему, фільтруючи кров

7 сімʼяники

8. сечовий міхур

9. сімʼяні міхурці

10. серце - являє собою розширену уздовж хребта судину з пʼятьма клапанами, що качають кров по дрібнішим судинним розгалуженням.

додатки:

а) на шкірі вздовж черева розміщени крихітні щілини (стигми/дихальця), які насичують кров киснем через поза легеневі трахеї

б) -

в) -

г) кишківник не поділяється на відділи, має свій особливий склад ферментів та займає мало місця в черевній порожнині

припущення:

овальні сектори на шлунку можуть бути травними та ендокринними [гормони] залозами, за рахунок чого їжа повністю перетравлюється у шлунку. а довжини кишківника як раз вистачає лише на всмоктування поживних елементів

знімається хірургічним шляхом без особливої шкоди для організму. в процесі фізичного дорослішання імплант замінюється на новий у відповідних інстанціях

—————————————————————

1. lungs — not as massive as in humans. Part of the respiratory system's functions are taken over by the integument (skin) [see Appendix "a"]

2. liver and spleen as a single organ [see Appendix "b"]

3. oesophagus

4. stomach [see Appendix "c"]

5. intestines [see Appendix "d"]

6. kidneys — based on malpighian vessels, responsible for the excretory system, filtering blood

7. testicles

8. bladder

9. seminal vesicles

10. heart — an elongated vessel along the spine with five valves that pump blood through smaller vascular branches.

appendages:

a) tiny slits (spiracles) are located on the skin along the abdomen, which saturate the blood with oxygen through extrapulmonary tracheae

b)

c)

d) The intestine is not divided into sections, has its own special composition of enzymes, and occupies little space in the abdominal cavity.

assumption:

the oval sectors on the stomach may be digestive and endocrine [hormone] glands, due to which food is completely digested in the stomach. the length of the intestine is just enough for the absorption of nutrients.

implant. It is implanted in the spinal cord at birth, does not grow nerve endings and does not feel pain, but reads impulses and is controlled like a separate limb [group of limbs].

It can be surgically removed without causing significant harm to the body. During physical maturation, the implant is replaced with a new one by the appropriate authorities.

I am currently working on a tumblr version of my main Dr script (I'm not copypasting from notion and revealing to everyone how I scripted out the entire human excretory system)

Any words of motivation are appreciated .-.

[crowttore]

This is why we don't stab straws into the penis to suck out bladder content like a capri sun. The bladder already has a very neat straw called the urethra.

And as indicated on the figure below, sucking someone's dick so hard their stomach caves in would be practically impossible. The part of our excretory system handling blood filtration is not open to the abdominal cavity, making it impossible to suck out anything that hasn't already passed from the blood vessels and into our kidneys, through the ureter, and into our bladder. If you want to make someone's stomach cave in from getting sucked, this is the time to stab them with a straw (not in the penis tho, in the abdomen without hitting any organs) and suck
