Which vessel carries blood from the abdomen and lower body to the heart?

• A. Inferior vena cava
• B. Superior vena cava
• C. Aorta
• D. Pulmonary artery

Answer: (A)

Blood returning to the heart from the abdomen and lower body travels through the large vein called the inferior vena cava. This vessel collects deoxygenated blood from below the diaphragm, including abdominal organs, pelvis, and lower limbs, and delivers it to the right atrium. Along its path it receives blood from various veins like hepatic, renal, and iliac veins, making it the main conduit back to the heart from the lower part of the body. In contrast, the superior vena cava drains the upper body, the aorta carries blood away from the heart to the body, and the pulmonary artery carries blood from the heart to the lungs.
