Explanation:

Five steps in the process of Nutrition in Animals

There are five steps in the process of Nutrition in animals. These are: Ingestion, Digestion, Absorption, Assimilation and Egestion.

Ingestion

is the process of taking food in to the body or ‘eating of food’ by the animal. When we put food in to our mouth with hands, we are ingesting it.

Digestion:

is the process in which the food containing large, insoluble molecules is broken down in to small, water soluble molecules which can be absorbed by the body or digestion is the dissolving of the solid food. Most of the animals include both physical and chemical methods for digesting the food. Physical method includes chewing and grinding the food in mouth and chemical method include the addition of digestive juices (enzymes) to food by the body itself.

Absorption:

is the process in which the digested food passes through the intestinal wall in to blood stream. As, after the digestion, food molecules become small and soluble. This food passes through the walls of our intestine and goes in to the blood.

Assimilation:

is the process in which the absorbed food is taken in by the body cells and used for energy, growth and repair. Blood carries the absorbed food to all the parts of the body.

Egestion:

is the process in which the undigested food is removed from the body. The whole food which we eat is not digested by our body, a part of the food remains undigested which cannot be used by the body and so it is removed from the body in the form of faeces when we go to the toilet.
