This is also known as the cardiovascular system! To sum its function up quick and easy, this system delivers nutrients and oxygen to all the cells in the body. Let’s look at it this way; this system is initially the heart and the blood vessels running throughout our body. The process is quite quick. The arteries carry the blood, away from the heart, then the veins manage to carry it back to the heart. It keeps the heart pumping, and keep us alive!

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
