Mucosa: Villi
Higher magnification of the mucosa shows its three components: a simple columnar epithelium of absorptive enterocytes and goblet cells; a lamina propria of loose connective tissue in which intestinal glands are located; and a thin muscularis mucosae of smooth muscle. Beneath the mucosa is the submucosa. Trichrome stain, 200x
