Why does the chamber of heart have thick walls?


The heart chamber has to generate enough pressure to push the blood to all the parts of the body.



  • If arteries have thin walls they would burst because of high blood pressure.
  • That is why arteries have thick walls. Because the heart pumps blood at high pressure.
  • They must be able to withstand the tremendous pressure from a beating heart.
  • Veins have thinner walls because they need more room to hold blood.
