Webb14 maj 2024 · Small intestinal mucosa is lined by a simple columnar epithelium which consists primarily of absorptive cells (enterocytes), with scattered goblet cells and occasional enteroendocrine cells . In crypts, the epithelium also includes Paneth cells and stem cells. Functional integrity of the mucosal epithelium is critical for normal function. WebbThe large intestine also has microvilli on the surface of its enterocytes. The brush border morphology increases a cell's surface area, a trait which is especially useful in absorptive cells.
