Why do Veins have thin walls as compared to arteries?
The pressure is higher in arteries than veins
The pressure of blood is higher in arteries than vein
veins have to pump blood into various organ, therefore , they have thicker muscular walls than the arteries
Arteries get all the pressure of pumping of heart and it have to bear that pressure so it has thick wall . But veins don\’t need so bcz there is no any pressure applied on veins instead veins have valves in it .
