Question Blood Oxygen Content

A large, multinational research institute is conducting experiments on human circulatory physiology. The oxygen content of aortic blood is measured in an apparently healthy 35-year-old volunteer at rest. Which of the following anatomic sites would normally have a blood oxygen content that differs the most from the value obtained from this healthy volunteer's aorta?

A. Portal vein
B. Coronary sinus
C. Internal jugular vein
D. Renal vein
E. Brachial vein
F. Pulmonary artery

I would go with A, portal vein, it has the lowest content of O2 from the others so it differs the most from the carotid in the healthy ones.
