Nephysio is a tool that seeks to provide a “one stop shop” for learners to understand the absorption and secretion of various solutes in the nephron under states of physiology, pathophysiology, and pharmacology.  We hope to bring renal physiology to life to make it fun and exciting, inspiring a future generation of nephrologists.
