Because the walls of veins have ______ compliance, they can accommodate a relatively ______ volume of blood with a relatively ______ increase in internal pressure.
Because the walls of veins have high compliance, they can accommodate a relatively large volume of blood with a relatively small increase in internal pressure.
What are veins?Veins are specific blood vessels of the circulatory system that transport deoxygenated blood to the hearth.
Vein blood vessels have high compliance to increase the volume of blood cells that can be transported.
During this process, the internal pressure of the walls in the vein blood vessel is minimized.
