Paneth cells are immune cells located in which part of the body?

• A. Lungs
• B. Gut
• C. Skin
• D. Liver

Answer: (B)

Paneth cells are specialized immune cells of the intestinal lining. They sit in the small intestine, at the base of the crypts of Lieberkühn, and release antimicrobial peptides like defensins and lysozyme into the gut lumen. This local, first-line defense helps control gut bacteria and maintain a healthy microbiome. They’re not located in the lungs, skin, or liver, which is why the gut is the correct location.
