College Answer

There was a wide range of marks for this question with a few candidates scoring excellent marks. Those answers that scored well provided a comprehensive list of functions as well as an explanation as to the what, how and/or why of these functions. Poorer answers omitted some of the functions or failed to elaborate on them by providing only a limited list. The second component of the question was generally well outlined, most candidates provided some estimate of normal values at term and a simple elaboration regarding the factors that affect placental blood flow.
