B) pulmonary arteries.
C) pulmonary veins.
D) coronary arteries.
E) bronchial arteries.

Accepted Answer

Lung tissue receives oxygen and nutrients from the bronchial arteries which branch off the aorta and provide blood supply to the bronchi and lung tissue itself. The pulmonary arteries, on the other hand, carry deoxygenated blood to the lungs for oxygenation. The pulmonary veins carry oxygenated blood from the lungs back to the heart. The pleural arteries supply blood to the membranes surrounding the lungs. The coronary arteries supply blood to the heart muscle.
