the circulatory system/cardiovascular system is a system which it’s just is to deliver nutrients to the cells in the body. Parts of the circulatory are the
heart which has four chambers which are:
right atrium: recieves deoxygenate blood and pumps it to the right ventricle.
right ventricle: pumps the deoxygenate blood to the lungs so it gets oxygenated.
left atrium : receives oxygenated blood and pumps it to the left ventricle
left ventricle: pumps oxygenetd blood to the rest of the body.
blood vessels:
Veins: they have oxygen-poor blood and they deliver it to the heart.
arteries: they have oxygen-rich blood and they get the blood away from the heart to the rest of the body.
capillaries: where blood exchange happens
