Study Notes
Digestive Enzymes
- The production of all 3 enzymes (protease, carbohydrase, lipase) occurs in the pancreas.
Stomach Function
- Hydrochloric acid in the stomach helps to denature proteins and activate pepsin, an enzyme that breaks down proteins into smaller peptides.
Small Intestine Structure
- Villi in the small intestine increase the surface area, allowing for more efficient absorption of nutrients into the bloodstream.
Sphincters in Digestion
- Sphincters in the digestive tract act as muscular rings that control the flow of food and prevent backflow, ensuring a one-way movement of food through the digestive system.
Large Intestine Function
- The primary function of the large intestine is to absorb water and electrolytes, and store and eliminate feces.
