However, endothelium lines the internal surfaces of the blood vessels, lymph vessels and the heart. Furthermore, based on the cell arrangements in the endothelium, it can be continuous endothelium or fenestrated endothelium. Structurally, mesothelium and endothelium are specialized or modified epithelial layers with mesodermal origin. At an event of damage to the blood vessel, the endothelium secrets thromboplastin; this helps the coagulation of blood and responds to cytokinase to increases the permeability to white blood cells. Endothelium is a thin layer composed of simple, squamous cells which line blood and lymph vessels, connecting the circulating blood/lymph to the lumen and rest of the vessel. Function of mesothelium. Endothelial cells form the barrier between vessels and tissue and control the flow of substances and fluid into and out of a tissue. Compare the Difference Between Similar Terms.

For that, the basal membrane is perforated by blood and lymph vessels and nerve endings for sense. Félétou, Michel. They are sensitive to blood pressure and secrete vasodilators such as prostacylin and Nitric oxide in response to a high blood pressure. The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. The pseudostratified epithelium is an alternative type of epithelium whose cell height varies.Transitional epithelium is another type of epithelia that allows urinary organs to be stretched. However, they have a different embryonic origin with epithelium having an ectodermal and endodermal origin and endothelium having a mesodermal origin. This tissue is avascular hence the adjoining connective tissue supplies it with food nutrients and energy through simple diffusion. Epithelium (/ ˌ ɛ p ɪ ˈ θ iː l i ə m /) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.It is a thin, continuous, protective layer of cells.Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. In comparing the two types of tissues, epithelium and endothelium, it could be said that their basic functionality is similar as in the secretary, protective and sensory functions. See more.
