What type of epithelial tissue are endothelium and mesothelium?

Question:

What type of epithelial tissue are endothelium and mesothelium?

Protective Sheets:

Epithelial tissue is comprised of epithelial cells. The cells can be column, cube, or flat shaped. The cells form sheets, and these sheets can provide single or multi layers of protection throughout the body.

Answer and Explanation: 1

Both endothelium and mesothelium epithelial tissue are single, squamous-celled tissue. This means that endothelium and mesothelium tissue is comprised of one layer of squamous (plate-shaped) cells. However, while similar in form and function as protectors, these tissue types are located in different regions in the body.

Endothelium tissue covers inner parts of the cardiovascular and lymphatic systems. This tissue lines things like arteries, veins, vessels, and capillaries, thus keeping them protected. Mesothelium tissue covers more middle components of the body, like the pericardium, peritoneum, and the reproductive organs. Thus, it's found in the chest and abdominal cavities.
