Diagram of Human Digestive System:

Digestive Process:
The digestion of food occurs in several stages:
1. Ingestion: Food is taken into the mouth and chewed.
2. Digestion: Enzymes break down food in the mouth, stomach, and small intestine.
3. Absorption: Nutrients from digested food are absorbed into the bloodstream through the small intestine.
4. Assimilation: Nutrients are utilized by body cells for energy and growth.
5. Egestion: Undigested food and waste materials are excreted through the large intestine.
