Question

BlackTom AI · Accepted Answer

In this question, we’re identifying a vessel type by its general function and direction of blood flow.
Option 1: coronary artery. These vessels supply the heart muscle itself with blood, not the entire body. They don’t carry blood away from the heart to all tissues, so this choice is incorrect for the stated role.
Option 2: lymphatic venules. Lymphatic vessels are part of the lymphatic system, not the cardiovascular system, and they transport lymph rather than blood. Since the question is about blood vessels, this option is not applicable and thus incorrect.
Option 3: aorta. The aorta is the main artery that carries oxygen-rich blood exiting the heart to all tissues throughout the body (except the lungs, which receive blood via the pulmonary arteries). This description matches exactly what the question asks about—the vessel that distributes oxygen and nutrients to the body. Therefore, this option is correct in terms of function and direction.
Option 4: vein. Veins return blood back toward the heart and typically carry deoxygenated blood (except for the pulmonary veins). They do not carry blood away from the heart to the tissues, so this choice does not fit the scenario described.
