The
cardiovascular system consists of the heart which is a muscular pump and
a double circuit of pipes or blood vessels that carry blood from the heart
to the lungs and back in one circuit, the pulmonary circulation, and to
the rest of the body and back to the heart, the systemic circulation. A
coronary system also exists to feed the heart muscle. Vessels that carry
blood away from the heart are called arteries, while those that return blood
to the heart are veins. This exercise will provide you with a fundamental
understanding of the basic anatomy and physiology of the cardiovascular
system in humans.
