What is a correct pathway for blood flowing through the heart?

A. right atrium, tricuspid valve, right ventricle, aorta
B. left atrium, tricuspid valve, left ventricle, pulmonary artery
C. right atrium, tricuspid valve, right ventricle, pulmonary artery
D. left atrium, left ventricle, bicuspid valve, aorta

C

Thanks to all the G2 comments received, it was realized that tricuspid and bicuspid valves were not always taught as such, but often, simply as the atrioventricular valves. This would mean that candidates who knew the structure of the heart and the pathway through it would not be able to answer the question. In order to solve this problem, although answer D was not correct, it was also accepted (as well as C) as a correct answer, giving these candidates the benefit of the doubt. Most of the good candidates still went for C as the correct answer.
