Glomerular Filtration Activity 1: Effect of Arteriole Diameter on Glomerular Filtration 1. Compare this data with your baseline data. How did increasing the afferent arteriole radius affect glomerular filtration rate? >>Increasing the afferent arteriole radius pushed the glomerular pressure‚ the glomerular filtration rate‚ and the volume of urine to be higher than the baseline data. Increasing the afferent arteriole radius increased the glomerular filtration rate. 2. Under these conditions

PHYSIOEX 9‚ ACTIVITY #3 Review Questions ACTIVITY #1 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out the neuron through the K+ leak channels? 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare with your predictions? 3. Explain why a change in extracellular Na+ did not significantly alter the membrane potential in the resting neuron? 4. Discuss the relative permeability
