Question:

why are arteries called pressure reservoirs? Which artery is likely to have highest systemic pressure and why?

Inactive
Sweetlin P.
Answer:

Arteries are called pressure reservoirs because they stretch and store mechanical energy. Their elastic fibers recoil and convert stored energy in the vessel into kinetic energy in the blood. Blood continues to flow through the arteries even when the ventricles relax. Elastic arteries are the largest arteries and have the largest diameter. They have well defined elastic lamellae, which allows their walls to stretch easily and accommodate surges of blood giving them the highest systemic pressure.
