The circulatory system is a system that transports nutrients
and collects waste materials for disposal in the human body.
The circulatory system consists of the central organs like,
hearth, blood vessels and blood.
The heart carries deoxygenated blood from the upper and
lower parts of the body and supply that blood to the right auricle of the
heart. Then his auricle passes the blood to the right ventricle and further it
passes the blood into arteries, which pumps the blood into lungs. It also then
passes to the left atrium of the heart.
