Human Digestion: A Step-by-Step Guide to the Digestive Process

The main steps of digestion in humans are:

1. Ingestion: This is the process of taking in food through the mouth.

2. Mastication: This is the process of chewing food in the mouth, which breaks it down into smaller pieces and mixes it with saliva.

3. Deglutition: This is the process of swallowing food, which moves it from the mouth to the stomach.

4. Gastric digestion: This is the process of digesting food in the stomach, which involves the action of stomach acid and enzymes.

5. Absorption: This is the process of absorbing nutrients from digested food into the bloodstream, which occurs in the small intestine.

6. Egestion: This is the process of eliminating undigested food from the body in the form of feces, which occurs in the large intestine.
