it is controlled by the heart, pumping blood around the body. and it is important because the blood contains oxygen which is needed for body parts... By:Emmy (fifth Grader)
The circulatory system is important because it moves blood through all parts of the body. It carries oxygen and nutrients to all parts of the body and removes carbon dioxide and other waste materials.
veins are important because they carry de-oxygenated blood from all parts of the body back to the heart , which sends blood to the lungs which then returns to the heart so that oxygen can be carried in the blood to all parts of the body. ( the body uses it in cellular respiration)
Iron is an important component for the parts of our blood that transports oxygen.
It gets blood across all of you heart.
The circulatory system is about the heart pumping blood around your body. The parts the system has are the heart, which pumps blood to the lungs, giving the blood oxygen, and then sends the blood around your body in blood vessels (more specifically, arteries, veins capillaries).So the important parts are the heart, lungs, and blood vessels or arteries, veins and capillaries
The parts of the blood are the formed elements (solid parts) and the plasma (the liquid in which the solid parts are suspended). The formed elements include red blood cells, white blood cells, and platelets.
