Which comes first - absorption or assimilation?

Solution

Digestion :
It is the process of breaking down the large, complex and insoluble substances into much simpler molecules.
It involves various steps like ingestion, digestion, absorption, assimilation and egestion.
The mechanical and chemical digestion takes place in the stomach.
Absorption is described as the process that occurs when digested food passes into the blood vessels in the wall of the small intestine through the active, passive or facilitated transport mechanism.
Assimilation is the process where the absorbed substances are transported through the blood vessels to different organs of the body to build complex substances.
Hence, we can conclude that absorption is the first to occur among the absorption or assimilation.
