What is tunica intima nedir?

Tunica intima, also known as the intima layer, is the innermost layer of a blood vessel. It is composed of a single layer of endothelial cells, supported by a thin layer of connective tissue. The tunica intima is responsible for maintaining the barrier between the blood and the vessel wall, regulating blood flow, and producing various factors that affect vascular function. Damage to the tunica intima can result in atherosclerosis, a condition in which plaque builds up on the inner walls of arteries and restricts blood flow.
