How the End-Products are Absorbed into the Blood Stream

The nutrients obtained from digestion are absorbed by the body.

The use of these absorbed end-products of digestion by the body (cells, tissues and organs) is known as assimilation

The nutrients enter the blood stream through diffusion.

This is done by the villus which is a small, finger-like projections that extends into the lumen of the small intestine.

The villus helps in the absorption in the small intestine. It has a thin wall, one cell thick which helps in the absorption of fatty acids and glycerol into the blood stream.
