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. ∙ Egestion - The process of removal of faecal matter through the anus is called egestion.
