Simple squamous epithelium can be studied by looking at cells which line blood and lymph vessels. These flattened cells are called endothelial cells . The nuclei are frequently found protruding into the lumen of the vessel. Observe the numerous large blood vessels present in the periphery of this section.
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.he 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.
