Which cells of "Crypts of Lieberkuhn" secrete antibacterial lysozyme ?
- Paneth cells
- Zymogen cells
- Kupffer cells
- Argentaffin cells
The Correct Option is A
Approach Solution - 1
- Kupffer-cells are phagocytic cells of liver.
- Zymogen cells are enzyme producing cells.
- Paneth cell secretes lysozyme which acts as anti-bacterial agent.
- Argentaffin cells are hormone producing cells.
Approach Solution -2
Explanation:
- Paneth cells- These are secretory cells that are located in the crypts of Lieberkühn of the small intestine. One of the main functions of Paneth cells is to secrete antimicrobial substances. Lysozyme is one of the main antimicrobial enzymes produced by Paneth cells which helps to protect the intestinal mucosa from bacterial infections.
- Zymogen cells- They are also known as chief cells and are found in the gastric glands of the stomach. Zymogen cells are responsible for secreting an enzyme called zymogen.
- Kupffer cells- are also called stellate macrophages. These cells are known as tissue macrophages in the liver. Kupffer cells help in digestion, detoxification, and storage and can help to improve liver immunity.
- Argentaffin cells are the epithelial cells which are present in the lining of digestive tracts. These cells are called hormone-releasing cells as they release a hormone called serotonin.
Therefore, the Paneth cells are the cells of “Crypts of Lieberkuhn" that secrete antibacterial lysozyme.

Concepts Used:
Digestion and Absorption - Alimentary Canal
Digestion can be defined as the process of breakdown of large, insoluble and complex food molecules into smaller ones for its absorption and circulation in the body. This process involves the usage of a variety of digestive fluids and enzymes, including saliva, mucus, bile and hydrochloric acid, among others.

The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed as the digestive tract.
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
