the breakdown of carbs begins in mouth, the breakdown of proteins in stomach, absorption = smallintestine

the stomach mixes

the small intestine is an organ of absorbtion

the large intestine is an organ of elimination

nutrients that penetrate the semi-permeable membrane of the small intestine enter the circulation by way of the hepatic circulation

The stomach produces gastric juice and mixes it with the food. This gastric juice contains enzymes that begin the digestion of proteins. Proteins are the only substances digested in the stomach. Proteins are only partially digested in the stomach. The food is churned and mixed with stomach fluids until a thick paste called chyme is produced. The chyme passes through the stomach into the small intestine.

The small intestine is a long, coiled organ about one inch in diameter. The small intestine may be 7.5 to 9 meters in length. Digestion is completed in the small intestine. The liver releases bile into the small intestine. Bile prepares the fats for digestion. Pancreatic juice contains enzymes that digest carbohydrates and fats. It also contains enzymes that continue the digestion of proteins. The walls of the small intestine release enzymes that complete the digestion of all three basic nutrients. In the walls of the small intestine are millions of small projections called villi. These villi contain many small blood vessels. Digested food is absorbed into these blood vessels and carried to all body cells.

The material that has not been absorbed moves into the large intestine, or colon. Here water and salts are absorbed, and the remaining solid waste goes out of the body
