  • pulmonary artery
  • (handwritten: takes blood from lungs to heart)
  • pulmonary veins
  • (handwritten: brings blood from lungs to heart)
  • aorta
  • superior/inferior vena cava
  • coronary arteries
  • (handwritten: gives blood to heart muscles)

Explanation:

Brief Explanations

To describe the function of major blood vessels:

  • Pulmonary Artery: Carries deoxygenated blood from the heart to the lungs (for oxygenation).
  • Pulmonary Veins: Carry oxygenated blood from the lungs back to the heart.
  • Aorta: The main artery that distributes oxygenated blood from the heart to the entire body.
  • Superior/Inferior Vena Cava: Carry deoxygenated blood from the upper (superior) and lower (inferior) body regions back to the heart.
  • Coronary Arteries: Supply oxygenated blood to the heart muscle (myocardium) to support its function.

Answer:

  • Pulmonary Artery: Carries deoxygenated blood from heart to lungs.
  • Pulmonary Veins: Carries oxygenated blood from lungs to heart.
  • Aorta: Distributes oxygenated blood from heart to body.
  • Superior/Inferior Vena Cava: Carries deoxygenated blood from body to heart.
  • Coronary Arteries: Supplies blood to heart muscle.
