Verified step by step guidance

Step 1: Understand the basic function of blood vessels. Blood vessels are responsible for transporting blood throughout the body. Arteries typically carry blood away from the heart, while veins carry blood toward the heart.

Step 2: Recall the difference between oxygenated and deoxygenated blood. Oxygenated blood is rich in oxygen and is typically carried by arteries, while deoxygenated blood is low in oxygen and is typically carried by veins. However, there are exceptions to this general rule.

Step 3: Focus on the pulmonary circulation. The pulmonary arteries are unique because they carry deoxygenated blood away from the heart to the lungs for oxygenation. This is an exception to the general rule that arteries carry oxygenated blood.

Step 4: Eliminate incorrect options. The aorta carries oxygenated blood from the heart to the body, the coronary arteries supply oxygenated blood to the heart muscle, and the pulmonary veins carry oxygenated blood from the lungs to the heart. These do not match the criteria of carrying deoxygenated blood away from the heart.

Step 5: Conclude that the pulmonary arteries are the correct answer, as they are the only blood vessels that carry deoxygenated blood away from the heart.
