The endothelium is composed of a single live cell layer, whereas the epithelium may have multiple layers of cells, which can be alive or dead. So, the inner wall of the entire circulatory system is covered with endothelial cells. it is present in any histological slide. The epithelial tissue is the covering of all external and internal body surfaces. By this definition, the endothelium is a type of epithelium. The mesothelium was first described in 1827 by Bichart, who observed that serous cavities were lined by a layer of flattened cells similar to those of the lymphatics. Endothelium and mesothelium are two types of tissues that line certain internal surfaces. Overview and Key Difference Hence, they all are protective barriers of the body. The basement membrane is a thin multilayered matrix that acts as an anchoring substrate for the epithelium, mesothelium, and endothelium and represents a separating barrier from the underlying connective tissue. It usually helps a smooth flow of fluid upon its surface. Other than in the circulatory system, the endothelium is found in the inner lining of the cornea as well. Both mesothelium and endothelium are single layered tissues. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology.

Le corps animal est composé de quatre types fondamentaux de tissus en fonction de leur structure et de leurs fonctions. The mesothelium and the endothelium both come from the mesoderm, and pathologists do not consider mesothelium or endothelium to be true epithelium. “The Endothelium.” Current Neurology and Neuroscience Reports., U.S. National Library of Medicine, 1 Jan. 1970. Endothelial cells are a lining layer of cells or tissue (endothelium), especially the interior of the blood vessels. 3. The reason why they are not classed as true epithelium is because the pathology of both endothelium and mesothelium is incredibly different. Pericardium. Endothelial cells form the barrier between vessels and tissue and control the flow of substances and fluid into and out of a tissue. Moreover, another difference between epithelium and endothelium is that the epithelium may have single cell layer or many cell layers. 2. 11. This tissue is avascular hence the adjoining connective tissue supplies it with food nutrients and energy through simple diffusion. Lv 4. They also help the exocrine function by the formation of glands. Structurally, mesothelium and endothelium are specialized or modified epithelial layers with mesodermal origin. The endothelium is a thin layer of supporting connective tissue that lines the internal surfaces of blood vessels, lymph vessels and the heart.
