WebIntroduction. Inflammatory bowel disease (IBD) is a chronic, relapsing disease of the gastrointestinal (GI) tract, with frequent onset during adolescence or early adulthood. IBD is characterized by chronic activation of the immune system with inflammation of the intestinal tract and leakage of fluid, solutes, and lipids in the bowel mucosa. WebIntestinal glands - Crypts of Lieberkuhn They are of two types namely, crypts of Lieberkuhn and Brunner's glands. 1. Crypts of Lieberkuhn. They are tubular structure that occur throughout the small intestine between the villi. They secrete digestive enzyme and mucus. The crypts have at the base paneth cells and argentaffin cells.

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.
