What is the difference between absorption and assimilation?
Absorption
Assimilation
S.No. | Absorption | Assimilation |
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. |
