The cardiovascular system
The cardiovascular system is an
organ system which allows blood to circulate and transports nutrients, gases, hormones,
and blood cells within the cells of the body for proper functioning of human
cells and organs. The cardiovascular system is made up of the heart and the
circulatory system. A group of arteries, arterioles, and capillaries help to carry
blood from the heart to other parts of the body.
