Which statement correctly lists the three kinds of blood vessels?

• A. Nerves, Muscles, Bones
• B. Arteries, Capillaries, Veins
• C. Lymphatics, Arteries, Veins
• D. Pleura, Alveoli, Bronchi

Answer: (B)

The main idea here is to know the three kinds of vessels that make up the blood-transport system. Arteries carry blood away from the heart, veins bring it back toward the heart, and capillaries are the tiny exchange points between them where oxygen, nutrients, and wastes move between blood and body tissues. The other options mix in structures that aren’t blood vessels: nerves, muscles, and bones are different tissues; lymphatics are part of the lymphatic system, not the blood vessels; and the pleura, alveoli, and bronchi belong to the lungs and airways. So the correct trio—arteries, capillaries, and veins—are the vessels that form the blood-transport network.
