Succus entericus is secreted by________

A

Brunner's glands

B

Auerbach's plexus

C

Crypts of Lieberkuhn

D

Peyers patches

Answer

Crypts of Lieberkuhn

Explanation

Solution

Succus entericus is secreted by the intestinal glands of the Crypts of Lieberkuhn.

Succus entericus or intestinal juice is secreted by intestinal glands. It contains enzymes such as maltase, sucrose, lactase, enterokinase, etc. Intestinal glands are formed by the surface epithelium of the small intestine. These are two types of crypts of Lieberkuhn and Brunner's glands. Succus entericus is majorly produced by the crypts of Lieberkuhn as these glands occur throughout the small intestine. They secrete digestive enzymes and mucus. Whereas, Brunner's glands are found only in the duodenum. They secrete mucus and a small number of enzymes. The mucus helps in protecting the duodenal wall from getting digested.
