Salivary Glands

- The rectum represents the final few inches of the intestine and ends at the anus.

- Digestion: breaking down food into simple chemicals that can be absorbed into the bloodstream.
- (No second function mentioned in the text)
Pylorus
- The pylorus is the lower area of the stomach, positioned close to where the stomach and the duodenum meet.
