Succus entericus

Succus entericus is the fluid produced by the glands in the lining of the small intestine. This fluid contains a variety of enzymes that are crucial in the digestion and absorption of food.

Composition

The succus entericus is composed of water, mucus, and enzymes. The enzymes include proteases, which break down proteins into amino acids; lipases, which break down fats into fatty acids and glycerol; and carbohydrases, which break down carbohydrates into simple sugars. The mucus in the succus entericus helps to protect the lining of the intestine and aids in the movement of food through the digestive tract.

Function

The primary function of succus entericus is to aid in the digestion and absorption of food. The enzymes in the fluid break down food into its constituent nutrients, which can then be absorbed into the bloodstream through the walls of the small intestine. The mucus in the succus entericus also helps to lubricate the intestinal walls, making it easier for food to pass through.

Production

Succus entericus is produced by the crypts of Lieberkühn, which are glands located in the lining of the small intestine. These glands secrete the fluid in response to the presence of food in the intestine.

Clinical significance

In certain medical conditions, the production of succus entericus can be affected. For example, in celiac disease, the lining of the small intestine is damaged, which can reduce the production of succus entericus and impair digestion. Similarly, in pancreatic insufficiency, the pancreas does not produce enough digestive enzymes, which can lead to a deficiency in the enzymes in the succus entericus.
