The process of Absorption of Digested Food

Amino acids and glucose molecules pass through the epithelia of the villi and capillary walls into the blood system by active transport.

The capillaries drain into the hepatic portal vein where the amino acids and glucose are carried to the liver before being allowed to join the general body circulation.

The fatty acids and glycerol are absorbed into the lacteals of the villi which drain into the lymphatic vessels.

The lacteal contents join the general lymphatic system which ultimately finds its way into the blood circulatory system.

The fatty acids and glycerol are then distributed to all parts of the body.
