Assimilation, << uh `sihm` uh LAY shuhn, >> is the process by which cells convert food into living tissues. This process makes possible the growth and repair of living organisms. In human beings, assimilation begins when food is broken down into simple molecules in the stomach. This process is called digestion. The bloodstream absorbs the digested food and carries it to all parts of the body. Then, the digested food is assimilated by the cells for use in the growth and repair of the body. See also Absorption and adsorption ; Cell ; Digestive system .
