What is ingestion?

Ingestion is the process of taking food into the body. It is the first step in the process of nutrition in animals.

In humans and many animals, ingestion occurs through the mouth, where food is taken in and prepared for further digestion. This may involve actions such as chewing and swallowing.

Ingestion is essential because it initiates the entire digestive process, allowing the body to obtain nutrients from food.

Without ingestion, the subsequent steps of digestion, absorption, and assimilation cannot take place.
