enterocyte of epithelium proper of small intestine enterocyte of epithelium proper of ileum https://cellxgene.cziscience.com/cellguide/CL_1000342 An enterocyte that is part of the epithelium proper of ileum. FMA:263102 Enterocytes of the epithelium proper of the ileum, commonly known as ileal enterocytes, are specialized epithelial cells found lining the inner surface of the ileum, the final section of the small intestine in the human body. They play a pivotal role in nutrient absorption, digestive metabolic functions, and the maintenance of the host’s immune response. Like enterocytes in other parts of the intestine, ileal enterocytes exhibit distinct characteristics specific to their function and role. They have microvilli on their apical surfaces to increase absorption and are important in the absorption of vitamins and the reabsorption of bile salts. These cells also produce enzymes that metabolize lipids and xenobiotics.
