Which group of vessels includes both veins and arteries?

Which group of vessels includes both veins and arteries?

• A. Veins and arteries
• B. Arteries only
• C. Veins only
• D. Capillaries only

Answer: (A)

Blood vessels come in three main types: arteries, veins, and capillaries. Arteries carry blood away from the heart, veins return it to the heart, and capillaries are tiny vessels that connect arteries and veins where gas and nutrient exchange occurs. The question asks for a group that includes both veins and arteries, so the correct choice is the one that names both of the major vessel types. The other options refer to only one type or to capillaries, which don’t include both arteries and veins together.
