How do arteries act as pressure reservoirs
WebHow do arteries act as pressure reservoirs? Arteries are resistance vessels. They store most of the flow energy as potential energy in a spring-like manner within the elastin and collagen fibers following their kinetic stretch, and subsequently release it kinetically, to accordingly facilitate blood flow.
