Discuss the major steps involved in process of nutrition in human beings.
Solution:
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 human beings:-
(i) Ingestion: This is the process of taking food into the body by the humans. When we put food in our mouth (buccal cavity) with our 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 bloodstream.
(iv) Assimilation: the process in which the digested food passes through the intestinal wall into the bloodstream 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.
