A. True  Pulmonary blood flowright ventricular outputcardiac output.

B. False  The O2 content of arterial and mixed venous blood are measured.

C. False  To measure O2 consumption, the subject breathes from a spirometer filled with oxygen with a CO2 absorber in the circuit; an open circuit method may also be used.

D. True  The pulmonary artery is relatively easy to catheterize and the venous blood it contains is thoroughly mixed.

E. False  Pulmonary veins are difficult to catheterize. Blood from any artery may be used since the O2 content of peripheral arterial blood is the same as that in the pulmonary vein.
