What do the veins do?
transfers blood towards the heart
The veins are part of the circulatory system and play a crucial role in transporting blood from various parts of the body back to the heart. Unlike the arteries that carry blood away from the heart, veins carry the deoxygenated blood from the body’s tissues and organs back towards the heart and lungs for replenishing it with oxygen and nutrients.
The veins also have valves that help to prevent the blood from flowing back or pooling in the legs due to gravity. These valves work by allowing for blood flow in one direction only, towards the heart. Overall, the veins play a critical role in maintaining proper circulation and oxygenation of tissues and organs throughout the body.
