Why do veins have elastic walls? Veins are made up of thin layers with a few circular elastic fibres and muscle fibres. This is because blood does not flow in pulses and so the vein walls cannot help pump the blood on. They have valves to prevent blood pooling at extremities (arteries do not have valves).

If you look closer at the arteries you will see that the distribution of fiber, elastic and muscle is optimized. The largest arteries like the aorta have more elasticity and fiber the smallest arteries which serve as controls for flow distribution the most muscle and probably the most neural receptors to allow control.

Arteries carry blood away from the heart to the rest of the body and are doing so with a lot of pressure . Hence the walls of the arteries are thick to enable it to withstand the blood pressure . they are elastic so that they can retain their original shape . they do not have valves also as the pressure is so intense,the blood will never flow back.

Both arteries and veins have thick muscle layers that surround them and the aorta has cardiac muscle in the walls, as well. The aorta is the largest artery and is connected directly to the heart. When blood flows from the heart and is forced into the arteries, they must expand to accept the blood and then contract to squeeze the blood into the …
