The breakdown of large, insoluble molecules into small, soluble molecules. The body has two ways of doing this - mechanical (teeth and stomach muscles) and chemical (enzymes and bile)
2 of 5
Absorption
The process of moving the molecules through the walls of the intestines into the blood. Digested food molecules are absorbed in the small intestine whilst water is mainly absorbed in the large intestine
3 of 5
Assimilation
When digested molecules have been absorbed, they move into body cells. They then become part of the cells. For example, when amino acids (from digested proteins) are assimilated, they are used by cells to make cellular proteins.
