Endothelial cells perform a variety of essential functions in the body. One of the primary functions of endothelium is to act as a semi-permeable barrier between body fluids (blood and lymph) and the organs and tissues of the body.
The blood-brain barrier is made up of very small blood vessels (capillaries) that are lined with thin, flat endothelial cells. In other parts of the body, endothelial cells have small spaces between them that allow substances to move in and out of the capillary so they can reach other cells and tissues.In the brain, the endothelial cells are packed tightly together so substances cannot pass out of the bloodstream into the brain.n other parts of the body, endothelial cells have small spaces between them that allow substances to move in and out of the capillary so they can reach other cells and tissues.
