Difference Between Endothelium and Mesothelium
Table of Contents
The main difference between mesothelium and endothelium is that, in adults, mesothelium occurs in all serous membranes of the body such as pericardium, peritoneum, and pleura and internal reproductive organs whereas the endothelium lines the inner surface of the blood vessels, lymphatic vessels, and the heart.
What is the difference between endothelial and epithelial?
Endothelial cells cover the inner surface of the blood vessel, while the epithelial cells cover the inner surface of the internal organs and the outer surface of the human body.
Is Mesothelium an epithelium?
The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic cavity including the mesentery, omenta, falciform ligament and the perimetrium) and pericardium ( ...
Where are endothelium and mesothelium located?
Mesothelium: Mesothelium is found in all the serous membranes of the body such as pericardium, peritoneum, and pleura and internal reproductive organs. Endothelium: Endothelium lines the inner surface of the blood vessels, lymphatic vessels and the heart.
Is endothelium a type of epithelium?
The endothelium is a layer of cells that lines the blood vessels and lymph vessels of the body. ... Endothelial cells are a type of epithelial cell – “epithelium” being the fourth major type of animal tissue, along with connective tissue, muscle tissue, and nervous tissue.
What can damage endothelium?
Endothelial dysfunction is likely to result from endothelial cell injury triggered via a number of different mechanisms, including the following [2]: bacterial or viral infection; oxidative stress through abnormal regulation of reactive oxygen species, hypoxia, turbulent blood flow and shear stress; environmental ...
What are the different types of epithelial cells?
The different types of epithelial tissues are characterized by their cellular shapes and arrangements: squamous, cuboidal, or columnar epithelia. Single cell layers form simple epithelia, whereas stacked cells form stratified epithelia.
What is the function of mesothelium?
Mesothelial cells form a monolayer of specialised pavement-like cells that line the body's serous cavities and internal organs. The primary function of this layer, termed the mesothelium, is to provide a slippery, non-adhesive and protective surface.
Where is Mesothelium found in the body?
The mesothelium is the layer of tissues (epithelium) that surrounds the organs of the chest (pleura and pericardium), abdominal cavity (peritoneum and mesentery), and pelvis (including the tunica vaginalis that surrounds the testes).
What is epithelium?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. ... Because the tissues form coverings and linings, the cells have one free surface that is not in contact with other cells.
Where are endothelium located?
Continuous endothelium is found in most arteries, veins and capillaries of the brain, skin, lung, heart and muscle. Endothelial cells are coupled by tight junctions and anchored to a continuous basal membrane.
What is the one type of epithelial cell that covers almost everywhere?
The human body is composed of four basic types of tissues, epithelium being one of them. It is present on almost every part of the human body, hence it has several important functions.

Is simple epithelia include endothelium and mesothelium?
The major body cavities (peritoneal, pleural, pericardial) are lined by a mesodermally derived simple squamous epithelium that is called mesothelium.
