Detailed explanation-1: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.

Detailed explanation-2: -Veins carry blood back to the heart. In all but one case, veins carry oxygen-poor blood. The exception is the pulmonary veins. They carry oxygen-rich blood from the lungs back to the heart.

Detailed explanation-3: -The right side of the heart pumps oxygen-poor blood from the body to the lungs, where gets oxygen again. The left side of the heart pumps oxygen-rich blood from the lungs to the body. Once the body’s organs and tissues have removed the oxygen from the blood, the blood returns to the heart. The cycle is then repeated.

Detailed explanation-4: -Final answer: Pulmonary vein does not contain deoxygenated blood.

Detailed explanation-5: -The pulmonary artery carries oxygen-poor blood to the lungs to receive oxygen. The pulmonary veins carry oxygen-rich blood from the lungs to the left atrium.
