Definitions:

Elastic Arteries

Arteries that contain elastic fibers in their walls, allowing them to stretch and recoil as blood is pumped through them by the heart.

Greatest Pressure

Typically refers to the highest pressure within the cardiovascular system, often associated with systolic blood pressure during heartbeats.

Arterioles

Small diameter blood vessels that extend from an artery and connect to capillaries, playing a key role in regulating blood pressure and flow.

Veins

Veins are blood vessels that carry blood toward the heart, typically carrying deoxygenated blood, except for the pulmonary and umbilical veins.
