Your 7th edition Moore text book (not study guide) says 20 weeks, so that answer would be accepted. I will make sure that Dr. McLaughlin is aware of this conflict.
: the answer to a study guide question states that pulmonary surfactant starts to form at 24 weeks.
: however, the notes from both Anna (TA) and Dr. McLaughlin state that surfactant production begins at 20 weeks.
: What are we supposed to answer if the study guide question appears on the exam??
