Components of the lining of the lining of the intestine.. Mucosal cells. Endothelial cells. Panet cells. Deaths. Cholestyocinine. Somatostatin. Gastrin, Kimoterpsin



This layer contains 4 different basic cell types:
Enterocytes (80%) play an important role in absorption.
Notes:
- The intestinal flora is a group of intestinal cells (there are about 40 flies / mm 2 in the drip).
- Tumors are inserted into the mucous layer and the Librocon glands, which are often located in the bottom of the pancreatic cells.
- Each tube contains microscopic vesicles (about 2000 micrographs that make the absorbent surface in the intestine about 200 m 2). There are also polycyclic plaques in these intestines and there are also very important digestive enzymes.
Abstract: The intestinal epidermis is coagulated to form a villus. It also penetrates into the special plate to give the libron glands. In the dermis, the epidermis reaches the subcutaneous layer to give the Brunner glands.
B) Calciforme cells that provide mucous secretions that contribute to the lubrication of the "intestine" within the intestine, which constitutes 15% of the epithelial cells.
C - Endocrine cells: give the digestive hormones with many functions such as:
- Motulin: incites movement.
- Colicastocinin: cck absorbs gallbladder and stimulates the secretion of yeast from the pancreas.
- Somatostatin: inhibitor.
- Gastrin, Kimoterpsin, VIP, GIP.
A few are not related to the glare of the intestine as they release their hormones directly into the blood.
Paneth cells: cells that secrete substances similar to pancreatic enzymes. They also perform a defensive function (phagocytosis), which is located deep in the libreon glands.
Note: The rate of regeneration of the intestinal cells is 3 to 4 days, so we can conclude that the least cancers encountered in the gastrointestinal tract are the small intestine cancers (colon and stomach) due to rapid cell regeneration (a cancerous growth will change cells quickly after 3 - 4 days).
