As the Baby Boomer generation reaches old age, there has been a significant increase in the number of older adults needing healthcare over the past decade. The physiology of aging is therefore a highly relevant topic for the preclinical medical curriculum. I describe a new capstone unit on the physiology of aging, placed at the end a medical physiology course, to provide a vehicle for integration of prior learning about physiology of each individual body system. Students were provided with online self-study modules as preparation for a mandatory small group case-based learning activity. A detailed case of an elderly female patient being assessed for fall risk was provided. Students were required to document a "Review of Systems" predicting decreased system functions due to senescence and to prepare a group concept map illustrating how physiologic deficits contributed to fall risk in the patient. Students successfully completed the activity and reported generally good satisfaction with the experience. The activity was judged an effective tool for students to consolidate prior learning and to apply physiology to an important medical topic. The lesson also provided several opportunities for curriculum integration with cell biology, biochemistry, anatomy, and clinical skills components.
