Question 6

How we digest food

Answer 6

1. Ingestion
2. Food is being broken down and mixed with saliva > via esophagus secretion
3. (Stomach) acid coming from the gastric glands gets mixed with the food
4. (Chyme) Exits the stomach and goes to the
5. Small Intestine (the major organ for digestion and absorption)
6. Further absorption occurs in the Large Intestine
7. Undigested materials are brought to the rectum (where they are stored until they are ready to)
8. Exit the body through the anus
