Final answer:
The three kinds of processing that food undergoes in the body are ingestion, digestion, and absorption.
Step-by-step explanation:
The three kinds of processing that food undergoes in the body are ingestion, digestion, and absorption.
- Ingestion: This is the process of taking in food through the mouth. It involves chewing and mixing the food with saliva to create a bolus.
- Digestion: This is the breakdown of food into smaller components that can be absorbed by the body. It consists of mechanical digestion, where food is physically broken down, and chemical digestion, where enzymes break down food into nutrients.
- Absorption: After food has been digested, the nutrients are absorbed into the bloodstream and transported to cells throughout the body.
