Explanation:
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: -Generally, veins carry deoxygenated blood from the body to the heart, where it can be sent to the lungs. The exception is the network of pulmonary veins, which take oxygenated blood from the lungs to the heart.
Detailed explanation-3: -The pulmonary vein carries oxygen around the body back to the heart. It, therefore, has the greatest oxygen content. The primary pulmonary artery, also known as the pulmonary trunk, is a blood vessel that leaves the heart.
