The Intestinal Epithelium – Fluid Fate and Rigid Structure From Crypt

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. WebLow birth-weight (LBW) neonates exhibit a lower growth rate and impaired intestinal development.
