Here’s a breakdown of how it works: Oxygenated Blood from the Lungs : Blood that has been oxygenated in the lungs returns to the left atrium of the heart via the pulmonary veins. Left Atrium to Left Ventricle : The left atrium contracts, pushing the oxygen-rich blood into the left ventricle. Pumping Blood to the Body : The left ventricle, the strongest of the heart’s chambers, then contracts forcefully to pump the oxygenated blood through the aorta and into the arteries, delivering oxygen and nutrients to tissues throughout the body. Deoxygenated Blood Returns : After delivering oxygen and nutrients, blood returns to the heart via the veins, carrying carbon dioxide and waste products. It first enters the right atrium. Right Atrium to Right Ventricle : The right atrium contracts, sending the deoxygenated blood into the right ventricle. Pumping Blood to the Lungs : The right ventric...
