The body's cardiovascular system, sometimes called the blood-vascular, or simply the circulatory system, is composed of a vast network of organs and blood vessels that act as both a delivery system and a waste removal system for the body.

This critical system works to deliver oxygen, nutrients, hormones, and other vital substances to cells and organs, while also helping the body during periods of activity, exercise, and stress.
