Simulating Glomerular Filtration
The following questions refer to Activity 1: Investigating the Effect of Flow Tube Radius on Glomerular Filtration. 1. Describe the effect of increasing the afferent radius on glomerular filtration rate and glomerular pressure. As the afferent radius increases the glomerular filtration rate and glomerular pressure both increase the pressure in slow steps the filtration rate greatly increases. 2. Describe the effect of decreasing the efferent radius on glomerular filtration rate and glomerular pressure. the efferent rate has the opposite effect as afferent. It increase both the glomerular pressure and filtration as it goes down. 3. Describe the effect of increasing the efferent radius on glomerular filtration rate and glomerular pressure. increasing the efferent radius decreases the glomerular pressure and filtration rate.

The following questions refer to Activity 2: Studying the Effect of Pressure on Glomerular Filtration. 4. Describe the effect of increasing the beaker pressure on glomerular filtration rate. increased the filtration rate

5. Describe the effect of increasing the beaker pressure on glomerular pressure. increased the glomerular pressure by large amounts
6. In the absence of any regulatory mechanisms, what effect do you think an increase in blood pressure would have on glomerular filtration rate? It would increase the glomerular filtration rate.

The following questions refer to Activity 3: Exploring Intrinsic Controls: Renal Autoregulation. 7. What was the glomerular filtration rate at 80 mm Hg beaker pressure, 0.55 mm afferent radius, and 0.45 mm efferent radius? 129.61

8. With the beaker pressure increased to 85 mm Hg, at what afferent radius was the glomerular filtration rate in question 7 restored? between 0.53 - 0.52 9. With the beaker pressure increased to 85 mm Hg, at what efferent radius was the glomerular...
