What kind of mechanical digestion takes place in your mouth?
12
Your teeth crunching and munching food.
13
Where does chemical digestion of bread begin?
14
In the mouth, where amylase breaks it into sugar!
15
Where does chemical digestion of proteins begin?
16
In the stomach, where gastric juice breaks it down.
17
Where does chemical digestion of starches END?
18
In the small intestine, with pancreatic juice.
19
What liquid that we have studied do you think will break down steak the most? Where in your body can you find that liquid?
20
•Gastric juice will break down steak the most because it is protein! •In your stomach.
21
Which solution was able to diffuse through the membrane?
22
Sugar solution because it is small enough for diffusion.
23
What was the most important thing you learned from the experiment with the egg whites?
24
Gastric juice does the best job of breaking down proteins.
25
1) What did the oil represent when we were squeezing the tennis ball? 2) What did your hands represent?
26
1) Mucus 2) Peristalsis (or muscle contractions)

When we did the egg white experiment, we had to let the egg white sit in the liquids overnight. When we did the amylase experiment, we tested for starch and sugar after only 5 minutes. Why did we have to wait such a long time for the egg white, but not for the amylase? 30
Because the amylase experiment was about your mouth. Food stays in your mouth for a short amount of time. But the egg white experiment was about your stomach. Food stays in your stomach for several hours! 31

A man named Stuart got into a serious accident. He lost half of his large intestine. His waste could still leave through the rectum, but half of the large intestine was missing. What problem do you think he was likely to have?
44
Your large intestine absorbs water. So if you lose some of your large intestine, less water will be absorbed, making your waste more watery and giving you…
Diarrhea!
