Gah! Cavity Sam here is not doing so great. He’s got junk in his body that definitely
00:07
should not be there. But, you know, like the fork and the knife in the belly and the heartburn
00:12
and the jackhammer head are easy problems to fix because Sam’s body does not come close
00:17
to the incredible complexity of what’s going on inside of you right now.
00:21
Your body is awesome, literally. The amount of stuff going on at any given time to keep
00:25
you alive and functioning is awe-inspiring. Trying to manipulate the tiny little tweezers
00:31
so you can retrieve the nail from poor Sam’s fingers is nothing compared to the challenge
00:35
of just trying to understand the systems that keep you operating. The human body is composed
00:40
of thousands of intricate pieces of biological machinery, which is part of why we rely on
00:45
two twin disciplines to talk about it here on Crash Course: anatomy and physiology. Anatomy
00:50
is the study of the structure and relationships between body parts, while physiology is the
00:55
science of how those parts come together to function and keep that body alive.
01:00
From grave robbers to microscopes, these fascinating disciplines have come a long way and we are
01:04
still discovering new things about how it all works. I’m not going to lie to you, it’s
01:07
tough. We’ll build on things that you learned in biology and chemistry and you’ll learn
01:11
more about cell specialization, how your epithelial tissue creates order out of the mayhem of
01:17
your body, and look at the important protection you get from your integumentary system. And
01:21
by the end of this course you’re gonna understand more about all of the complicated things your
01:25
body is up to right now while you’re sitting there at home watching this video, and maybe
01:29
you’ll appreciate what a wondrous thing that body of yours truly is.
01:33
To be clear, that is not a real x-ray.
01:35
It’s Photoshop.
01:37
So join us for a new year of Crash Course where I, Hank Green, talk about all of this…
01:41
stuff and hopefully help us all understand a little more about ourselves with Crash Course:
01:48
Anatomy and Physiology.
01:50
(Game buzzes) Duhh! Homeostasis.
