, The Cardiovascular System
The cardiovascular system includes the heart, blood and all blood vessels in the body.
The heart itself, is a major organ that propels blood through the circulatory system by pumping.
The heart is located between the lungs, in the center and a bit to the left of the body’s midline.
The heart helps deliver oxygen and nutrients to the body’s cells as well as carry away waste product.
