Current Question (ID: 14480)

Question:
Arteries have _______ layer of smooth muscles than _______
Options:
  • 1. thicker, vein
  • 2. thicker, aorta
  • 3. thinner, vein
  • 4. thinner, aorta
Solution:
Arteries are muscular and elastic blood vessels that carry oxygenated blood away from the heart to the body tissues. They have thicker walls and more smooth muscle fibers than veins, which enables them to withstand the high pressure generated by the heart's pumping action. The thickness of arterial walls varies depending on their location and function in the body. Veins, on the other hand, are blood vessels that carry deoxygenated blood from the body tissues back to the heart. They have thinner walls and less smooth muscle fibers than arteries, which makes them less able to withstand pressure. Instead, they rely on the surrounding muscles and gravity to help propel blood back to the heart.
