A Living Conveyor Belt: Glomerular and Renal Tubule Filtration

An active learning demonstration, using a homemade conveyor belt, where students act out the production and flow of filtrate through the renal tubule. Filtration scaled by size, selective reabsorption, and secretion are all demonstrated. Certain processes such as spilling glucose in diabetes mellitus and the intrinsic control system of the juxtaglomerular feedback mechanism are then visualized more effectively.
