how does lungs purify blood?

Asked by Vishal Thimmaia...(student) , on 30/4/12

Answers

    • The right atrium then contracts and passes the de-oxygenated blood to the right ventricle, through an auriculo-ventricular aperture.
    • Then the right ventricle contracts and passes the de-oxygenated blood into the two pulmonary arteries, which pumps it to the lungs where the blood becomes oxygenated. From the lungs, the pulmonary veins transport the oxygenated blood to the left atrium of the heart.
    • Then the left atrium contracts and through the auriculo-ventricular aperture, the oxygenated blood enters the left ventricle.
    • The blood passes to aorta from the left ventricle. The aorta gives rise to many arteries that distribute the oxygenated blood to all the regions of the body.
    • Hence Blood Is Oxygenated And Therefore Purified.
