What is enterocyte?

Enterocytes are specialized cells found in the lining of the small intestine and are responsible for absorbing nutrients from the food we eat. These cells have a large surface area created by microvilli, which are tiny finger-like projections on the surface of the cell membrane. This increased surface area allows for more efficient absorption of nutrients such as sugars, amino acids, and vitamins.

Enterocytes play a crucial role in the digestion and absorption of food. They have specific transport proteins and channels that facilitate the movement of nutrients across the cell membrane and into the bloodstream. These cells also secrete digestive enzymes and other substances that help break down food particles into smaller molecules that can be absorbed.

In addition to their role in nutrient absorption, enterocytes also play a role in the immune system. They help to maintain the integrity of the intestinal barrier and prevent harmful substances from entering the bloodstream.

Overall, enterocytes are essential for proper digestion, nutrient absorption, and maintaining the health of the gut.
