Question

Systemic venous blood that is to be oxygenated in the lungs is delivered by the ____________, and the ____________ provide oxygenated systemic blood to lung tissue.

Answer 1

I believe the answer is pulmonary vein/ Bronchial artery. Pulmonary vein is the vein that carries deoygenated blood form the heart to the lungs for it to be oxygenated where carbon dioxide is exchanged with oxygen. Carbon dioxide is the exhaled from the lungs to the atmosphere. The bronchial arteries (both left and right) arise directly from the thoracic aorta and supplies oxygenated blood to the lung tissue.
