An intestinal crypt is a home to Paneth cells that secrete AMPs and control segregation.
it's the intestinal crypts, or crypts of Lieberkuhn

Intestinal Crypts
The structures that produce new cells for the mucosa of the small intestines are the intestinal crypts. These crypts contain stem cells that continually divide and give rise to new cells that migrate up and replace the old cells on the surface of the intestinal lining. This process helps maintain the integrity and functionality of the mucosa.
They are intestinal cells found in the Small Intestine (SI). They are in the inter-villi space (between villi) and project down into the lamina propria of the SI. They contain Paneth cells, which secrete lysozymes.
In the adult intestines, the stem cells that generate new cells to protect the tissues are located in the intestinal crypts. These stem cells are found at the base of the crypts and continuously divide to produce new cells that migrate upwards to replace the older cells that line the intestinal surface.
present in the small intestine, they secrete digestive enzymes
Crypts of Lieberkuhn
The function of intestinal villi is to aid in the efficient and rapid absorption o nutrients.
Intestinal glands, also known as crypts of Lieberkühn, are located within the lining of the small intestine and the large intestine. These glands are found in the mucosal layer, specifically in the intestinal epithelium, and they play a crucial role in secreting digestive enzymes and mucus. They help facilitate digestion and absorption of nutrients as well as maintain the health of the intestinal lining.
The tubular glands found between the bases of the intestinal villi are called crypts of Lieberkühn. These glands secrete mucus, enzymes, and hormones that aid in digestion and nutrient absorption in the small intestine.
In adults, the stem cells responsible for generating new cells to protect the intestines are primarily the intestinal stem cells located at the base of the intestinal crypts in the intestinal epithelium. These stem cells continuously divide and differentiate into various cell types, including enterocytes, goblet cells, and Paneth cells, which are essential for maintaining the integrity of the intestinal barrier and facilitating nutrient absorption. They play a crucial role in the rapid turnover and repair of the intestinal lining, especially in response to injury or inflammation.
