but only around 200 different types?

For example, the cells inside your cheek

are made up of stratified

squamous

epithelium cells

designed to handle constant abrasion.

These type of cells are not only in your cheeks, but also in your vagina and

anus as well.

Hey guys, I'm Christine Sydelko and I'm here with ASAP Science and we're talking about why your body is amazing

and mine is amazinger.

When you are an embryo, the first opening that developed was

your anus.

That's right, you were once just a butthole.

That means you are a Deuterostome

and so is a sea urchin.

Christine how much gas do you think exist in your anus in one day

Science says that today about half a liter of gas exist in your anus

and I say that too, I just said it

If it feels like too much, don't worry as your brain already

does a pretty good job of censoring content. Like your nose

Your nose is

The region that is blocked by the one eye is visible

for the other eye, and the brain constructs a

unified image and therefore you ignore your nose

but your nose is so powerful. In fact

if you convert your nose receptor neurones into binary code

it's the equivalent of 46 petabytes

that's more information than every movie

ever made after 2017. Convert all the cells in

your body and will add up to

91.44 zettabytes

or 10^21 bytes. Scientist hypothesized that during

pregnancy you gave some cells to your mum

I just gave gratitude

This process is called Fetal Maternal...

Scientists has found fetal cells and various maternal tissues

that can persist for decades. The reason for this is unclear

but one hypothesis is that the baby is trying to increase

its chance of survival. When your heart stops, your brain actually

knows that you're dead. A study that investigated
