Heart & blood vessels
The cardiovascular system is the heart together with the arteries, veins, and capillaries that circulate blood through every tissue of the body.
About heart & blood vessels
Gray's Anatomy (1918) describes the heart as a four-chambered muscular pump lying in the middle mediastinum, and traces the great vessels — aorta, venae cavae, pulmonary artery and veins — that carry blood to and from it.
