This station will introduce the urinary tract (kidneys, ureters, bladder) to students by paralleling its function to that of a municipal water treatment plant. Our blood is vital for transportation of nutrients (energy production), maintaining hydration, and ridding the body of waste products. The urinary system’s major role is to eliminate waste, maintain adequate hydration, acid/base balance, and control blood pressure all done through the continuous filtration of blood. The students will participate in active functions of filtration, diffusion, selective transport, and osmosis–all functions done routinely by our kidneys. They will also be introduced to the vital role kidneys take in the body maintaining homeostasis.
