The flow of blood follows a specific path called blood circulation.Blood Flow PathDeoxygenated blood (walang oxygen) galing sa katawan → pumapasok sa right atrium ng puso.Mula sa right atrium → papunta sa right ventricle.Right ventricle → lungs (via pulmonary artery) para doon kumuha ng oxygen.Sa lungs, nagiging oxygenated blood.Oxygenated blood → bumabalik sa puso sa left atrium.Left atrium → papunta sa left ventricle.Left ventricle → ipinapadala ang oxygenated blood sa buong katawan sa pamamagitan ng aorta.Ito ang tinatawag na double circulation: pulmonary (puso–baga) at systemic (puso–katawan).
Blood flow, or circulation, is the movement of blood through the body's network of blood vessels, delivering oxygen and nutrients to tissues and removing waste products. It follows a specific pathway, starting from the heart, through arteries, capillaries, veins, and then back to the heart.
