Valves of the venous system
Name the valves of the venous system? Also explain their function?
Expert
The valves of venous system are structures within the veins which allow blood to flow just in the normal way (that is, from the tissues to the heart) and forbid it to return in reverse way in the favor of gravity. The valves close whenever the pressure of fluid column above (subsequent to, concerning normal flux) is greater than the fluid pressure before them. The valves are therefore basic for the returning of blood to heart.
