Digestion
It is the process of breaking down the large, complex and insoluble food molecules into small, simple and soluble molecules, which can be easily absorbed into the bloodstream.
Absorption
It is the process of absorbing the digested food molecules into the blood or lymph.
The absorption process occurs by active or passive or facilitated transport mechanism.
Assimilation
It is the process of synthesizing simple macromolecules absorbed from the digested food molecules. The assimilation process helps in the growth and development of cells, tissue and also in the production of new cells and tissues.
