ANATOMY

Detailed explanation-1: -The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

Detailed explanation-2: -Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

Detailed explanation-3: -The freshly oxygenated blood is transported by the pulmonary vein from the lungs to the left atrium of the heart.

Detailed explanation-4: -Freshly oxygenated blood is first received by the left atrium. When blood gets oxygenated from the lungs, it enters the left atrium through the pulmonary veins. Oxygenated blood then passes through the bicuspid valve and enters the left ventricle.

Detailed explanation-5: -BLOOD VESSELS Arteries carry fresh, oxygen-rich blood away from the heart to tissues throughout the body. Veins carry blood containing waste products such as carbon dioxide back through the heart to the lungs.
