endothelium

 [en″do-the´le-um] (pl. endothe´lia) (Gr.)
the layer of epithelial cells that lines the cavities of the heart and of the blood and lymph vessels, and the serous cavities of the body.

(en'dō-thē'lē-ŭm, -lē-ă), [TA]
A layer of flat cells lining, especially blood and lymphatic vessels and the heart.
[endo- + G. thēlē, nipple]

endothelium

[en′dōthē′lē·əm]
Etymology: Gk, endon + thele, nipple
the layer of simple squamous epithelial cells that lines the heart, the blood and lymph vessels, and the serous cavities of the body. It is highly vascular, heals quickly, and is derived from the mesoderm.

endothelium

The single layer of flattened cells that lines the blood vessels, the heart and some of the cavities of the body. Endothelium is no longer regarded as simply a non-stick lining. It is now known to be a physiologically and biochemically dynamic structure that exerts a regulatory control on the tone of blood vessels and on the blood flow, mainly by the release of the hormone NITRIC OXIDE. It regulates the growth and repair of blood vessels; modulated the contraction and relaxation of the heart; protects blood cells from damage; helps to control the inflammatory process; prevents blood clotting within vessels; and offers a selectively permeable barrier to the passage through it of molecules.

endothelium

a layer of flattened, simple, epithelial cells, one cell thick, lining a tube such as the heart, blood vessels and lymph vessels of vertebrates.

endothelium

layer of highly metabolically active, flat squamous cells lining the entire circulatory system, including heart
