- Understand the morphological relationships between the kidney tubules and the circulatory system
- Analyze experimental data for calculating glomerular filtration rate
- Set up and perform a perfusion of renal tubules, including the calculation of liquid absorption rates
- Learn about the epithelial transport mechanism in the kidney tubules
- Use experimental data to assess the mode of action of a diuretic drug
Kidneys play a critical role in the filtration and reabsorption of essential substances that are required for the body. In this simulation, you will explore the anatomy of the kidney through 3D holograms and identify the physiological roles in maintaining homeostasis as well as the factors that influence urine regulation.
In this simulation, you will use the kidney from a dissected rat to study the mode of action of a new diuretic drug and learn the reabsorption process in the renal tubules. You will learn how to calculate the glomerular filtration rate or GFR and learn the hormones that influence urine output. At the end of the simulation, you should be able to correlate the relationship between renal and circulatory systems in controlling blood pressure.
