Nutrients and other chemicals get absorbed through the lining in the intestines; they are then transported to the rest of the body through the blood system.
small intestine
The end products of digestion, such as nutrients and water, are absorbed into the bloodstream in the small intestine. Specifically, absorption occurs through the villi and microvilli lining the walls of the small intestine, where nutrients are then transported to various cells and tissues throughout the body for energy and other functions.
The end products of lipid digestion are absorbed into the intestinal cells and then packaged into chylomicrons to be transported through the lymphatic system and eventually into the bloodstream for delivery to cells throughout the body.
The main process by which most products of fat digestion are absorbed by the body is through the small intestine. Fat digestion occurs in the small intestine where bile and enzymes break down fats into fatty acids and glycerol. These smaller molecules are then absorbed into the bloodstream through the lining of the small intestine and transported to cells throughout the body for energy or storage.
In the small intestine
The lacteal absorbs the products of lipid digestion from the small intestine to the bloodstream.
active transport
The digestion of proteins is completed in the small intestine. Enzymes produced by the pancreas and the small intestine break down proteins into amino acids, which are then absorbed into the bloodstream for distribution to the cells of the body.
The small intestine is where the vast majority of digestion and absorption of food takes place.
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
The Small Intestine.
The digestion finishes at the Small intestine.
