All right, so here we have a picture of what looks like it could be anybody, including yourself.
00:08
And we have identified the gi track, g .i.
00:12
Track, also known as gastrointestinal track or also as digestive track.
00:16
So we're going to take ourselves right here, and we're going to add a piece of pizza to demonstrate what digestion would look like in the process of it.
00:27
So here we have a lovely pizza pizza with some pepperoni on it.
00:32
And let's say that we just ate this slice of pizza.
00:36
Now, once we eat the slice of pizza, digestion is going to begin in the oral cavity right here because guess what? we have to chomp on that pizza and begin breaking it down.
00:47
It then goes down our digestive track and it comes over to the stomach through that sphincter there.
00:54
So in the process of coming to the stomach, what happens is the stomach is going to use its gastric acid to begin breaking down this food.
01:02
Think even though i took small bites of that pizza and swallowed it that way, it can't go fooling those big chunks through my small intestine.
01:11
That's just too big and it's not going to work very well.
01:14
So the acid in my stomach is going to even further break it down even more to make absorption easier.
01:20
So again, stomach's going to begin breaking down that food even more than what i have already.
01:27
Now it's going to go from the stomach there, continue its way down, passing a few organs there.
01:33
And we're going to come back to those right now.
01:35
But it's going to go here to the small intestine.
01:38
Small intestine is that smaller stringing looking organ there.
01:42
That is quite long.
01:44
And in the small intestine, it's now been broken down even further than when we were chomping it down...
