Please explain the whole process of nutrition in human being
Nutrition is the process of obtaining food and then using it for obtaining energy, growth and repair of the body.
These are the steps in the process of nutrition in Animals :-
(i) Ingestion : This is the process of taking food in to the body by the animal. when we put food in our mouth with hands, we are ingesting it.
(ii) Digestion : Digestion is the breakdown of large insoluble food molecules into small water. Soluble food molecules so that they can be absorbed into the watery food plasma.
(iii) Absorption : The process in which the digested food passes through the intestinal wall in the blood stream.
(iv) Assimilation : the process in which the digested food passes through the intestinal wall into blood stream and absorbed food is taken in by the body cells and used for energy, growth and repair.
(v) Egestion : Process in which the undigested food is removed from the body.
