In the process of digestion, complex food molecules are broken down into macromolecules which are absorbed by the body. The absorption of nutrients such as glucose, vitamins, and amino acids takes place in the small intestine.

The small intestine contains tiny hair-like projections called the microvilli that are rich in blood vessels. These structures help in the absorption of nutrients.
