GENERAL HISTOLOGY

Detailed explanation-1: -Endothelial cells form a single cell layer that lines all blood vessels and regulates exchanges between the bloodstream and the surrounding tissues.

Detailed explanation-2: -Your endothelial cells make up the lining of your blood vessels. They’re the cells that come into direct contact with your blood. They’re attached to a structure called your basal lamina. Together, your endothelium and your basal lamina form the innermost layer of your blood vessel wall (the tunica intima).

Detailed explanation-3: -Endothelium = the simple squamous epithelium lining blood vessels.

Detailed explanation-4: -2.1. 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.
