Question 2

What type of blood vessel carries blood AWAY from the heart?

Answer: Arteries carry blood away from the heart. The mnemonic 'A for Away' helps recall this distinction.

Question 3

Answer: The three layers are the tunica intima (innermost), tunica media (middle), and tunica adventitia (outermost).

Question 4

What is the primary structural difference between veins and arteries?

Answer: Arteries have thicker, more muscular walls to withstand high pressure; veins have thinner walls and contain valves to prevent backflow of blood.
