The intestinal epithelium is part of the intestinal mucosa. The epithelium is composed of a single layer of cells, while the other two layers of the mucosa, the lamina propria and the muscularis mucosae, support and articulate the epithelial layer. To securely contain the contents of the intestinal lumen, the cells of the epithelial layer are joined together by tight junctions, thus forming a contiguous and relatively impermeable membrane.

The enterocytes in the small intestinal mucosa contain digestive enzymes that digest specific foods while they are being absorbed through the epithelium. These enzymes include peptidase, sucrase, maltase, lactase and intestinal lipase. This is in contrast to the gastric glands of the stomach where chief cells secrete pepsinogen.
