Biology IIA continues the study of biology beyond the first-year course and places an emphasis on topics relevant to health-related fields. The amount of work required outside of class and the difficulty of the material studied is greater than in first-year biology. First semester topics include human anatomy and physiology, with sub-topics focused on each of the major body systems and with an extended dissection of a fetal pig. Second semester topics include nutrition with an emphasis on how nutrition affections cellular functions.
