The correct answer is Option B.
Succus entericus is also known as Intestinal juice . It is an alkaline secretion which is produced by Glands in the wall of the Duodenum. And it is secreted by Crypts of Lieberkunh. It protects the duodenum from getting damaged.

Succus Entericus

Succus entericus, also known as intestinal juice, is a digestive secretion produced by the glands of the small intestine. It plays a crucial role in the process of digestion and absorption of nutrients.

Function of Succus Entericus

Intestinal juice helps in the digestion of various components of food, including proteins, carbohydrates, and fats. It contains several enzymes that break down complex molecules into simpler forms that can be easily absorbed by the body.

Composition of Succus Entericus

Succus entericus is composed of water, electrolytes, mucus, and enzymes. The enzymes present in intestinal juice include:

1. Peptidases: These enzymes break down proteins into smaller peptides and amino acids.
2. Sucrase, maltase, and lactase: These enzymes break down complex carbohydrates into simple sugars.
3. Lipases: These enzymes break down fats into fatty acids and glycerol.

The presence of these enzymes in succus entericus helps in the further breakdown of food particles that have not been completely digested in the stomach and small intestine.

Role in Digestion

Succus entericus is released into the small intestine, specifically the duodenum, where it mixes with chyme (partially digested food) from the stomach. The enzymes present in succus entericus act on the chyme, breaking down complex molecules into smaller, more absorbable forms.

The peptidases break down proteins into amino acids, which can then be absorbed by the intestinal lining and transported to the bloodstream. The carbohydrase enzymes break down complex carbohydrates into simple sugars, such as glucose, fructose, and galactose, which are also absorbed by the intestinal lining. The lipase enzymes break down fats into fatty acids and glycerol, which are further broken down and absorbed by the body.

Conclusion

In conclusion, succus entericus, or intestinal juice, is a digestive secretion produced by the small intestine. It contains enzymes that play a crucial role in the digestion and absorption of proteins, carbohydrates, and fats. Succus entericus helps break down complex molecules into simpler forms that can be easily absorbed by the body, aiding in the overall digestive process.
