The correct answer is Villi.

  • Capillaries are called very tiny blood vessels.
  • The Capillaries expand like a mesh in the whole body.
  • Through these capillaries, blood is transported to all parts of the whole body.
  • The arteries are the blood vessels that carry blood from the heart.
  • All arteries carry oxygen-rich blood, except for pulmonary and avascular arteries.
  • A tube that carries blood from the body to the heart and returns back is called a 'vein'.
  • 'Villy' is a structure found in the intestine that helps to absorb nutrients from the food eaten.
