For the endothelium of the cornea, see corneal endothelium. Endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.It is a thin layer of simple squamous cells called endothelial cells.hese functions include fluid filtration, such as in the glomeruli of the kidney, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. Endothelium of the interior surfaces of the heart chambers is called endocardium.
Introduction to Endothelial Cells. Endothelial cells (Fig.1) line the inside of every blood vessel in the body. They form a one-cell-thick layer called the endothelium, which is also found on the inner walls of the heart chambers and lymphatic vessels (which carry excess blood plasma around the body).The endothelium is very extensive.ain Function of Endothelial Cells. The main job of endothelial cells is to provide a barrier between the blood and the rest of the body tissues. Blood must be contained inside the transporting vessels, but substances need to move in and out of it in a controlled manner.
