The valves in the heart are: the tricuspid valve, which is called the right A-V valve, and is between the right atrium and the right ventricle, a bicuspid valve (Mitral valve), also called the left A-V valve between the left atrium and the left ventricle, the pulmonary valve, which is a semilunar valve, between the right ventricle and pulmonary trunk and the aortic valve, also a semilunar valve, between the left ventricle and aorta.

∙ 11y agoMany veins, particularly those in the upper and lower limbs, have flaplike valves, which project inward from their linings. Valves areusuallycomposed of two leaflets that close if blood begins to backup in the vein. These valves aid in returning blood to the heart, but close if it is in the opposite direction.
Arteries do not contain valves
Capillaries contain precapillary sphincters, which may close a capillary by contracting or open it by relaxing. A precapillary sphincter responds to the demands of the cells the capillary supplies.
