NEET PG DENTAL EXAM

Detailed explanation-1: -Veins comprise valves, which prevent the backward flow of the blood. The valves are bicuspid, that is, they comprise two flap-like compositions. In the veins, the valves ensure that the flow of blood takes place only in one direction. On the other hand, arteries carry oxygenated blood away from the heart.

Detailed explanation-2: -Veins have valves that prevent the backward flow of the blood.

Detailed explanation-3: -The deep veins play a significant role in pushing blood toward the heart. The one-way valves in deep veins prevent blood from flowing backward. The muscles surrounding the deep veins squeeze the veins, helping force the blood toward the heart, just as squeezing a toothpaste tube ejects toothpaste.

Detailed explanation-4: -You may know that your veins transport blood to the heart, but you might not know as much about the structure of these blood vessels. For example, did you know that your veins are equipped with a set of valves that ensure your blood flows through them properly?
