What are the steps in animal nutrition?
Nutrition in Animals take place in 5 steps
- Ingestion
- Digestion
- Absorption
- Assimilation
- Egestion
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.
