Q: The right pulmonary artery is –––––.
  • A. longer than the left
  • B. wider than the left
  • C. shorter than the left
  • D. of same size as the left
Correct Answer: Option A - The right lung is shorter, because the liver sits high, tucked under the rib cage, but it is broader than the left. The left lung is smaller because of the space taken up by the heart. The pulmonary artery begins at the base of the heart's right ventricle. It is approximately 3 cm in diameter and 5 cm in length and it eventually divides into the left pulmonary artery and the right pulmonary artery. The right pulmonary artery is longer than the left pulmonary artery. These arteries then deliver oxygen depleted blood to each corresponding lung.
