Let’s look at them one by one

Ingestion:

The process of taking food into the body is known as Ingestion.

Digestion:

The process in which the food containing large insoluble substances is broken down into smaller water soluble units (which can be absorbed by the body) is known as digestion.

Absorption:

The process in which digested food passes through the intestinal wall into the bloodstream is called absorption.

Assimilation:

The process in which absorbed food is taken in by the body cells and used for energy , growth and repair is known as assimilation.

Egestion:

The process by which leftover food waste is removed from the body is known as egestion.
