How do blood flow through our body?

Deoxygenated blood flows from the body into the superior and inferior vena cavas and then into the right atrium. Then through the tricuspid valve and into the right ventricle, and out through the pulmonary valve, into the pulmonary arteries, and into the lungs. Hemoglobin binds to oxygen in the lungs and then the now oxygenated bloods flows through the pulmonary veins and into the left atrium. The blood then goes through the bicuspid/mitral valve and into the left ventricle. Then through the aortic valve and through the aorta, to the rest of the body.

So it comes in the right of the heart, and out the left.

In brain, hand and leg, which sides do blood flow first? what is the order of blood flowing?


Thanks you very much for any suggestions
