Ingestion

Ingestion is the process of taking in food or other substances into the body through the mouth. It is the first step in the process of digestion, where food is broken down and absorbed by the body to provide nutrients and energy.

During ingestion, food is chewed and mixed with saliva in the mouth, forming a bolus that is then swallowed and passed down the esophagus into the stomach. In the stomach, the food is further broken down by stomach acids and enzymes before moving into the small intestine for further digestion and absorption.
