Endothelium

Epithelium of mesoblastic origin composed of a single layer of thin, flattened cells that line the cavities of the heart, the lumina of blood and lymph vessels, and the serous cavities of the body.


A layer of epithelium that lines the heart, blood vessels (endothelium, vascular), lymph vessels (endothelium, lymphatic), and the serous cavities of the body.


The layer of epithelial cells that line blood vessels throughout the body. The layer selectively allows the passage (from bloodstream to tissues) of nutrients, hormones, and other molecules that are essential for tissue growth and function. The endothelium is involved in the recovery and recycling of old red blood cells. It also produces two compounds that prevent blood clotting: prostacyclin and Von Wille-brand factor.


A layer of flat cells lining blood and lymphatic vessels corresponds to the mesothelium of the serous cavities.


A membrane of special cells which lines the heart, the lymph vessels, the blood vessels and various body cavities.


Layer of flat cells that lines the heart, blood and lymph vessels, and some body cavities.


The smooth layer of cells that forms the interior lining of the heart, the blood and lymphatic vessels, and the cavities of the body.


The single layer of cells that lines the heart, blood vessels, and lymphatic vessels. It is derived from embryonic mesoderm.


The membrane lining various vessels and cavities of the body, such as the pleura (lining the lung), the pericardium (lining the heart), the peritoneum (lining the abdomen and abdominal organs), the lymphatic vessels, blood vessels, and joints. It consists of a fibrous layer covered with thin flat cells, which render the surface perfectly smooth and secrete the fluid for its lubrication.


A form of squamous epithelium consisting of flat cells that line the blood and lymphatic vessels, the heart, and various other body cavities. It is derived from mesoderm. Endothelial cells are metabolically active and produce a number of compounds that affect the vascular lumen and platelets. Included are endothelium-derived relaxing factor (EDRF), prostacyclin, endothelium-derived contracting factors 1 and 2 (EDCF1, EDCF2), endothelium derived hyperpolarizing factor (EDHF), and thrombomodulin.


Endothelial cells form a layer that coats the heart, blood vessels, and lymphatic ducts. These cells are squamous, meaning they are thin and flat, which offers a slick surface that promotes the smooth flow of blood and lymph. Additionally, this smooth surface assists in preventing the development of thrombi, or blood clots.


The one-cell-thick membrane that lines the interior of the heart, blood and lymph vessels, capillary walls, lymphatic spaces, and serous cavities.
