The innermost coat of a blood vessel. Also known as tunica intima.



(tunica intima vasorum), the inner coat of the blood vessels (except the capillaries).

The intima consists of a layer of endothelium, a layer of loose connective tissue underneath, and an inner elastic membrane that separates the intima from the tunica media. The intima forms pocketlike valves in the veins, permitting the blood in the vessels to flow in only one direction.
