ANATOMY

Detailed explanation-1: -What are Venous Valves? Venous valves are flap like structures that control blood flow in the deep veins. To ensure vein health, learn about the functionality of and potential problems with the venous valves of the deep veins.

Detailed explanation-2: -Vein valves are made of a protein called collagen. The characteristics of collagen vary slightly from person to person, with some people producing more flexible collagen while others produce a version that is relatively stiffer.

Detailed explanation-3: -These vessels are lined by endothelial cells and have a very thin layer of smooth muscle. Like veins, lymphatic vessels have valves that prevent back flow.

Detailed explanation-4: -The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells.
