The American Physiological Society (APS) has teamed up with a range of partners to create the APS Archive of Teaching Resources. Part of their work includes crafting thematic collections of high-quality & interactive resources for use in a variety of undergraduate anatomy and physiology courses. This particular set of materials deals with the renal system, and visitors will find four useful instructional activities here. As a whole, these materials address the operation of the renal structure, with a focus on kidney development. The items include laboratory exercises like "Renal Regulation of Urine Output" and "Renal Structure & Function Activities." Additionally, the site includes "Web-HUMAN," which offers a wonderful physiology simulation that covers the six major core systems of the human body.
