Endothelial Cell
An Endothelial Cell is a squamous epithelial cell that compose the Endothelium.
- Context:
- They can range from being a Vascular Endothelial Cell to being a Lymphatic Endothelial Cell.

- Endothelium refers to cells that line 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. They form the barrier between vessels and tissues and control the flow of substances and fluid into and out of a tissue.
Endothelium is a thin layer of simple, or single-layered, squamous cells called endothelial cells. Endothelial cells in direct contact with blood are called vascular endothelial cells, whereas those in direct contact with lymph are known as lymphatic endothelial cells.
Endothelial cells line blood vessels and lymphatic vessels, they are found exclusively in vascularized tissue. so, vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries.
These cells have unique functions in vascular biology. These functions include fluid filtration, such as in the glomerulus of the kidney, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. Endothelium of the interior surfaces of the heart chambers is called endocardium. An impaired function can lead to serious health issues throughout the body
