Answer: C

Explanation:

The aorta is the largest artery in the human body and originates from the left ventricle of the heart. It carries oxygenated blood from the heart to the rest of the body. The coronary arteries supply oxygenated blood to the heart muscles, while the pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. The blood in the pulmonary artery is low in oxygen and high in carbon dioxide. The pulmonary veins return oxygenated blood from the lungs to the left atrium of the heart. Any obstruction in the coronary arteries can cause a heart attack.
