intestinal epithelium

The intestinal epithelium is the innermost lining of our digestive system's intestines. It consists of tightly packed cells that form a protective barrier and play a crucial role in nutrient absorption from food. These cells continuously renew themselves, which helps maintain gut health and protect against harmful substances. The epithelium also produces mucus and enzymes that aid digestion. Overall, it’s essential for efficiently processing food, absorbing nutrients, and defending the body against infections.
