Solution

Absorption

  1. The process of absorbing digested food molecules into our bloodstream and delivering them to their intended destinations is known as absorption.

Assimilation

  1. After being delivered by the blood or lymph, assimilation is the process by which absorbed nutrients from meals are used in the tissues for diverse functions such as energy production, development, and repair.
S.No.AbsorptionAssimilation
1.Absorption is the process of taking simple molecules created as a result of digestion from the intestinal cavity into the body (bloodstream/lymph).Assimilation, on the other hand, is the process of forming new compounds from absorbed molecules, which are required for regular cell function or energy production.
2.When it comes to where they happen, absorption happens mostly in the small intestine, while assimilation happens in the liver. Furthermore, while nutrients are absorbed into the bloodstream, molecules are removed from the bloodstream by different cells during assimilation.
