Blood first starts at the the heart where two loops cross.The first loop blood travels to the lungs and then come backs to the heart.The second loop blood travels through the body then come back to the heart.When the heart pumps blood the arteries receive the blood.Then the arteries go every where in your body.Then transports the blood to the veins and then every thing comes back to the heart. The cardiovascular system is very important for our body.Because the system consists of the heart,blood,vessel.The cardiovascular system is also important because it delivers needed substances to cells.And carries waste products away from the cell so they dont get harmed.They also contain blood cells that fights disease.So like cancer so the dont die off.The blood transports oxygen from the lungs.Blood cells also take away carbon dioxide from the cells.
