Question

At which anatomical location do Paneth cells reside?

a. crypts of the intestinal tract
b. the lining of blood vessels
c. in the urogenital tract
d. in the liver adjacent to Kupffer cells
e. alveolar spaces of the respiratory tract.

Answer 1

Paneth cells reside in the crypts of the intestinal tract and secrete antimicrobial peptides to protect the intestinal epithelium.

Step-by-step explanation:

Paneth cells reside in the crypts of the intestinal tract. Intestinal glands called crypts of Lieberkühn are located between the villi of the small intestine, and these glands are where Paneth cells can be found. Paneth cells secrete antimicrobial peptides and other substances that help protect the intestinal epithelium from harmful bacteria.
