SCIENCE HW

1.      What are the two parts of digestion?
The Stomach and Small Intestine.
2.      How do those two parts differ?
The intestine is a lot weaker than the stomach. If you small intestine starts bleeding, there is not an easy way to stop it. The stomach can store things and all-like-a-that.
3. People who have lost most of their teeth may have trouble chewing their food. How does this affect their digestive process?
It may mean that they don’t get enough food and may get choked easier. It also means that the pieces of food may go down longer which makes things bigger and harder to store.
3.      What is the pH in your mouth? Stomach? Small intestine?
The normal is about 7 for your mouth. The stomach is about 2.0 which means it’s a pretty strong acid. The small intestine is about 8.
4.      Why are pH variations in different parts of the digestive system important to the process of digestion?
They vary because of the things that those 3 parts are used for in your digestive system.
