The various steps of nutrition in animals are:

Ingestion − The process of taking in of food into the body is called ingestion. Ingestion of food in humans is done with the help of the buccal cavity.

Digestion − The process where conversion of food into soluble form occurs.

Absorption− The nutrients from the digested food are absorbed in the small intestine with the help of finger-like projections called villi.

Assimilation− The absorbed nutrients are transported via the blood vessels to the different organs, to be utilised for different life processes.
