Answer to Question 1

ANS: B
The third function is nonrespiratory and participates in the production, processing, and clearance of a large variety of chemicals and blood clots.

Answer to Question 2

ANS: D
The vascular supply of the lungs is composed of the pulmonary and bronchial circulations. The pulmonary circulation carries mixed venous blood from the systemic circuit to the lungs to in-crease O2 and reduce carbon dioxide content of blood. The bronchial circulation provides sys-temic arterial blood to the airways and pleura to support their metabolic needs. A network of lymphatics is also involved in fluid transport from the lungs. The lymphatic system removes fluid from the lung tissue and pleural space and returns it to the systemic circulation.
