Answer: A- Aorta carries blood away from the heart to the rest of the body.
Explanation: Cardiovascular systems function is to carry nutrients and oxygen via the blood using the heart. This systems comprises of arteries and veins. Arteries carry oxygenated blood away from the heart to the rest of the body whereas veins carry deoxygenated blood from the body to the lungs.
Aorta is a large artery that carrries oxygenated blood and distribute it to all the arteries that further directs it to different locations.
The superior vena cava is a large vein that takes deoxygenated blood that was circulating from the upper body part to the body to the right atrium of the heart.
Inferior vena cava is a large vein that takes deoxygenated blood from the lower and middle part of the body to the heart.
Pulmonary artery carrries deoxygenated (carbon dioxide) rich blood from the right ventricles to the lungs for oxygen collection.
Capillaries are minute blood vessels that transfer oxygen and nutreints from blood to the tissues and they also collect waste and sends them back to the blood.
Therefore the answer is option A.
