What are Capillaries, and Veins

2 Answer

  • Arteries, veins and capillaries. There are three main types of blood vessels: arteries take blood away from the heart to the body organs and tissues. The artery wall is thick and muscular so it can withstand the high pressure of the blood being pumped directly from the heart.
  • capillaries are  fine branching blood vessels that form a network between the arterioles and venules. veins are tubes that form part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
