So the first part of this question is asking about the different organs that are involved in digestion.
00:07
So the first thing you need to understand is that there's two types of digestion, mechanical and chemical.
00:12
And there are different parts of the body that are assisting with those.
00:17
So in terms of mechanical digestion, this is going to begin in the oral cavity where your teeth and tongue are going to help grind food up into smaller pieces.
00:30
You're also going to have an organ, the salivary glands in the oral cavity, that is actually going to begin chemical digestion.
00:42
So your salivary glands secrete saliva to begin chemical digestion.
00:48
From the oral cavity, food is going to go down the esophagus into the stomach.
00:53
Into the stomach, we're going to have, again, both types of digestion.
00:59
So in the stomach, there's a lot of churning.
01:03
You have muscles that are contracting and churning that food around, breaking it down.
01:08
The stomach is also going to have chemical digestion occurring as it secretes gastric juices.
01:16
That's going to break down food into smaller pieces.
01:18
From the stomach, you're going to move into the small intestine...
