Assimilation:

The process by which we utilize the absorbed energy from digested food for maintaining all physiological and physical metabolic functions, is called assimilation.

What is the difference between Absorption and Assimilation?

• Absorption is taking simple molecules, which were produced as a result of digestion. Assimilation is making new compounds from the absorbed molecules, which are required to produce energy.

• Absorption is mainly taking place in the small intestine. Assimilation is taking place in the liver or any other cell.

• In absorption, nutrients are added to the blood stream or lymph, but in assimilation, nutrients are taken out from the blood stream/ lymph for use.
