It was expected candidates would describe the salient features of the anatomy, distribution and 
content of blood flow and influences on each circulation. Answers with a clear organisation and 
context for the normal influences of blood flow on the functioning of each organ system scored 
highly. Anatomy was often sufficiently covered, but candidates often did not take advantage of 
that by linking the anatomical features to the functional concepts. Figures should be clearly and 

accurately labelled to score well. Many answers failed to demonstrate a depth of understanding 
of key concepts. For example tubuloglomerular feedback, relationship between hepatic arterial 
and portal venous flows and autoregulation within both those systems was often poorly 
described.
