The Circulatory System

  • The aorta is the main artery that distributes oxygenated blood from the heart to the rest of the body.
  • The superior and inferior vena cavae are the two vessels that return deoxygenated blood from the body to the heart.
  • The main function of the pulmonary artery is to transport deoxygenated blood from the heart to the lungs for oxygenation.
  • The pulmonary veins are the vessels that return oxygenated blood from the lungs to the heart.

Test your knowledge on the roles of the aorta, vena cava, pulmonary artery, pulmonary vein, and coronary arteries in the circulatory system. Understand how these blood vessels facilitate the flow of oxygenated and deoxygenated blood within the body.
