Endothelial cells make up the endothelium of capillaries. These cells form a single layer lining the interior surface of blood vessels, including capillaries, and play a crucial role in regulating the exchange of substances between the blood and surrounding tissues.
The tunica interna of a blood vessel is a single layer of endothelium with a basal lamina.Connective tissue
Single layer of Simple Squamous Epithelium
Endothelium
large surface area, thin epithelium, highly profused with blood vessels and lymphatics
wow your joking right its the heartThe heart pumps blood through the blood vessels.
well, smoking makes the blood vessels alot thinner than they usually are, and tbat makes it harder for the blood to be pumped to the brain.
Long term alcohol use causes the blood vessels to become more fragile and prone to rupture. Alcoholics have a much higher risk of stroke, aneurysms esophageal varicies and bleeding disorders.

The lungs have a large number of blood vessels because blood vessels carry oxygen to the lungs and the lungs need a lot of oxygen.Because it makes the transfer of oxygen from the lungs to the bloodstream quicker.
when blood is in vessel, the blood may be black.
Endothelial cells are able to sense changes in their surrounding environment, and release molecules that have a powerful effect on blood pressure and blood flow, coagulation (blood clotting), inflammation and oxidation. It also controls passage of materials in and out of the bloodstream. A healthy endothelium will prevent blood from clotting while it flows inside the blood vessel. It will also keep the blood vessel dilated. These properties makes it an important defense mechanism against atherosclerosis and cardiovascular diseases
