the main organs of cardiovascular system are, The heart, blood
vessels and blood.
the primary function of cardiovascular system is to circulate
nutrients, oxygen, and hormones all over the body and removal of
wastes(carbondioxide and nitrogenous waste) from the body.
Heart: the function of the heart is pump blood all over the
body.heart transports the oxygenated blood that comes from the
lungs to all parts of the body. it also collects all the
deoxygenated blood from the body and sends it to lungs.
blood: blood is the transport medium of nutrients and oxygen. the
movement of oxygen, nutrients and hormones all over the body is
carried out by blood. blood mainly transports oxygen and
carbondioxide throughout the body which is responsible for the
process of respiration. it transports nutrients from digestive
system to storage sites of the body. it also transports hormones
from their site of production to the target cells. blood maintains
the temperature to regulate the activity of the body.
blood vessels: the path in which the blood flows through the body
is laid by blood vessels. blood vessels contain arteries,veins and
capillaries. arteries carry blood away from the heart and veins
carries blood to the heart. capillaries sorround body cells and
tissues to deliver oxygen and other nutrients.
