Question

veins have the capacity of retain shape ? why?
​

Answer 1

Explanation:

The veins have valves in them to control the blood flow and to prevent the back flow of the blood. The arteries can retain the shape when there is no blood or when cut across.

Answer 2

Answer:

$\huge {The\ arteries\ can\ retain\ the\ shape\ when\ there\ is\ no\ blood\ in\ them,\ the\ veins\ cannot\ retain\ the\ shape\ or\ collapse\ when\ blood\ is\ absent.}$

Scroll it ......

Reason :

Veins do not experience the pressure waves that the arteries do. Therefore, they do not need to be as structurally robust, and they are not.
