has 4 chambers and valves that connect the chambers

They are: right atrium, left atrium, right ventricle, left ventricle

The main function of Human circulatory (Cardio vascular system) is transporting blood, oxygen, carbon dioxide and other necessary things to and from every cell in the body.

Blood circulation( starting point ):

From the vena cava (the vena cava which is best known for the biggest vein in the heart) the deoxygenated blood travels through the first 2 chambers, which is the right atrium and then after that it will go to the right ventricle. Then it will go out from the chambers which it makes it way through the pulmonary arteries and it goes to the lungs to pick up oxygen, which then makes the blood oxygenated. Back from the lungs into the pulmonary veins, it then go to the left atrium and then to the left ventricle. Then the blood gets released through the aorta. The aorta  is the biggest artery in the circulatory system and spreads it through all parts of the whole body to provide cells and other things with new, fresh and clean blood.
