facts about the human body

107 Facts About Bee Movie, because every time they said “bee,” we came up with a fact. 

Males typically have a higher basil metabolic rate than females.

At around the age of 15, females have finished majority of their growing. Males on the other hand, continue to grow and develop more lean muscle mass. Having more of this lean tissue means an increased mitochondria count to burn energy, and more tissues that require that energy to begin with.

Dirk: The human body is amazing, Todd! Even if the heart stops, it can be FORCED to beat again!
Todd: Dirk…
Dirk: And look! I
refused to take the shirt you gave me off! I didn’t even get shot in it once! I mean, yes, it’s a bit dirty at present, but nothing a good scrub can’t fix! 

@princessparadoxical and @itofoceania ‘s headcannon of season two Dirk walking around on a cocktail of drugs spouting out ‘fun’ facts about the human body is heartbreaking. So of course I had to draw art! To add to the headcannon, Blackwing attempted to make Dirk change his shirt to a company regulation type, but Dirk in an unusual show of resistance kicked up a massive fuss and straight up refused to part with it 

Fun fact: A 70 kg human body contains about 0.0187 grams of potassium-40, a natural radioactive isotope of potassium, and its decay produces about 4,900 disintegrations every second.

We found the number of disintegrations in a recent Nuclear Physics lecture, but we made some roundings so I took these numbers from Wikipedia. Anyway, neat, right?

Gardienne: I know a bit about medicine!

Ewelein: Well, try to impress me with your facts about the person.

Gardienne: Hmm…

Gardienne:  The average human body contains enough sulphur to kill all fleas on an average dog, carbon to make 900 pencils; potassium to fire a toy cannon, fat to make 7 bars of soap; enough water to fill a barrel of 50 liters.

Ezarel: *took a little knife*

Ezarel: In this case, you’re not as useless as I thought~

10 Facts About Water + Your Body

Water is virtually everywhere, from soil moisture and ice-caps to the cells inside our own bodies. On a normal, day-to-day basis, maintaining a well-hydrated system is easy to manage for those of us fortunate enough to have access to clean drinking water. So what role does water play in our bodies , and how much do we actually need to drink to stay healthy?

1. Depending on factors like location, fat index, age and sex, the average human is between 55 and 60% water. 

2. At birth, human babies are even wetter – being 75% water they are swimmingly similar to fish - but their water composition drops to 65% by their first birthday. 

3. The H2O in our bodies works to cushion and lubricate joints, regulate temperature and to nourish the brain and spinal cord. 

4. Water isn’t only in our blood: an adult’s brain and heart are almost three-quarters water - that’s roughly equivalent to the amount of moisture in a banana. 

5. Lungs are 83% water, which is roughly the amount of moisture in an apple.

6. Even seemingly dry human bones are 31% water. 

7. Each day we lose 2 to 3 liters through our sweat, urine and bowel movements, and even just from breathing. While these functions are essential to our survival, we need to compensate for the fluid loss.

8. Maintaining a balanced water level is essential to avoid dehydration or overhydration - both of which can have devastating effects on overall health. Increased dehydration can cause notable drops in energy, mood, skin moisture and blood pressure as well as signs of cognitive impairment.  In fact, a dehydrated brain works harder to accomplish the same amount as a normal brain - and it even temporarily shrinks because of its lack of water.

9. For a long time, conventional wisdom said that we should drink eight glasses a day. That estimate has since been fine-tuned; now the consensus is that the amount of water we need to imbibe depends largely on our weight and environment. The recommended daily intake varies from between 2.5 to 3.7 liters of water for men and about 2 to 2.7 liters for women - a range that is pushed up or down if we are healthy, active, old or overheating. But don’t go crazy - it’s possible to overhydrate if you consume too much water in a short amount of time - a risk mostly encountered by athletes because of complications in regulating water levels in extreme physical conditions.

10. Water within food makes up about a fifth of our daily H20 intake. Fruits and vegetables like strawberries, cucumbers and even broccoli are over 90% water and can supplement liquid intake while providing valuable nutrients and fiber.

Drinking well might also have various long-term benefits. Studies have shown that optimal hydration can lower the chance of stroke, help manage diabetes and potentially reduce the risk of certain types of cancer. No matter what, getting the right amount of liquid makes a world of difference in how you’ll feel, think and function day-to-day.

From the TED-Ed Lesson What would happen if you didn’t drink water? - Mia Nacamulli

sethkate week | day 1: favorite scene from the episode they met (1.04)

‘stop defining people by their genitals’ as if being male or female actually defines you. as if there is nothing else to being human than your sex. its just a fact about your body, it doesnt define you. your sex doesnt define you.

5 fun facts about your body

Starting at the top.

1. You’re already using 100% of your brain. The idea that humans only use 10% of their brain capacity is a myth made popular by hucksters and movies.

From the TED-Ed Lesson What percentage of your brain do you use?

2. You cry three types of tears: basal, reflex and emotional tears. As far as scientists can tell, humans are the only species that cry for emotional reasons.

From the TED-Ed Lesson Why do we cry? The three types of tears.

3. When you overeat sugary foods, you crave more of them. That’s because an overload of sugar spikes dopamine levels and leaves you wanting more.

From the TED-Ed Lesson How sugar affects the brain.

4. Whether you’re left-handed or right-handed, you were born that way. Today, about one-tenth of the world’s population is left-handed.

From the TED-Ed Lesson Why are some people left-handed?

5. Sitting for a long time is bad for your health. That’s because the human body is built for movement. Take a deep breath, stand up and stretch!

From the TED-Ed Lesson Why sitting is bad for you.

@ppl who refuse to tag pictures of naked people as nsfw bc “the human body is beautiful and there’s nothing sexual about it!”

look I completely agree with you about the fact that the human body is not inherently sexual and that people with breasts should be able to go topless just like people without breasts but that is still not a work-safe image tagging things as nsfw has nothing to do with what you think is sexual or not

Science Talk, Brain Weirdness, and Body Chemistry

Since I’ve been blabbing about this a lot as a result of trying to shove actual science into the context of midichlorians with @sanerontheinside and all the other lovelies contributing, it made me think about thoughts I had when I was first learning about this stuff, that I think are important to be shared.

To start, chemistry is hard.  A lot of people I’ve talked to are surprised when I say that I was pursuing and now have a B.S. in Chemistry, and that I plan on continuing to a Doctoral degree.  Which means a lot of people never learn the really nitty gritty details about how chemistry, and specifically body-chemistry works.

The fact that the human body (that any multicellular organism’s body) actually functions is a bloody miracle, because essentially the fact that the chemical reactions that make our cells do things that make out tissue do things that makes organs do things that makes the brain do things so that it can tell other things to do things… is all up to statistical probability, more or less.

So, for anyone and everyone suffering from some sort of hormonal disorder or a syndrome or neuroatypicality-related disorder… Y’all, the fact that your body doesn’t “function perfectly” the way the ideal/baseline/established norm works isn’t ‘weird’.  The fact that we function at all is fucking wild, and don’t let anyone ever tell you that whatever you need to help yourself and your body work in a way that allows you to live your life well is wrong.

Because that is fucking bullshit.  If you need medication? Don’t be ashamed to take it, and for all the anybodies who wants to harass you about it, I’d be happy to introduce their face to my fist.  If putting the hair-dryer in the passenger seat of your car keeps you from driving to and from your home constantly to check that it’s not plugged in.  Hell, go for it!  Whatever it is that you need, you deserve it.

Everybody is radically different, and the human body’s chemical functioning is a goddamned shitshow.

Everyone deserves a chance to live their life in a way that accommodates their needs.

Yeah, that means you.
