what what is blood circulatory system

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
