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. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of 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: -Arteries are responsible for carrying blood to organs, traveling away from the heart, while veins are responsible for transporting blood back toward the heart. Arteries generally carry oxygenated blood to deliver oxygen to organs, and veins generally carry deoxygenated blood back to the heart for re-oxygenation.

Detailed explanation-4: -Veins bring blood to your heart. Arteries take blood away from your heart. Your heart valves help control the direction the blood flows.
