Answer:
Freshly oxygenated blood enters the heart through the <u>pulmonary vein into the left atrium</u> and is pumped out the <u>left ventricle through the aorta.</u>
Explanation:
Deoxygenated blood is collected from all over the body by the superior and inferior vena cava and enters the top-right chamber of the heart called the right atrium. This blood then flows into the right ventricle where it is carried by the pulmonary artery to the lungs for oxygenation. The oxygenated blood is then carried back to the heart by the pulmonary vein and enters the top-left chamber of the heart called the left atrium. This blood then flows into the left ventricle which pumps the blood into the aorta which carries oxygenated blood to all the other parts of the body.
