If you increase the efferent arteriole radius and keep all other variables constant, the glomerular filtration rate would You correctly answered: b. decrease. 4. If you decrease the afferent arteriole radius and keep all other variables constant, the volume of urine flowing into the urinary bladder would. You correctly answered: b. decrease. 03/31/14 page 3 Review Sheet Results 1. What are two primary functions of the kidney? Your answer: 1. Excrete Excess water and wastes 2. Regulate homeostasis 2. What are the components of the renal corpuscle? Your answer: Glomerulus and Glomerular (Bowmans) capsule 3. Starting with the renal corpuscle, list the components of the renal tubule as they are encountered by filtrate. Your answer: Proximal convoluted tubule — Loop of Henle — Distal convoluted tubule — collecting duct 4. Describe the effect of decreasing the afferent arteriole radius on glomerular capillary pressure and filtration rate. How well did the results compare with your prediction? Your answer: By decreasing the radius of the afferent arteriole, the glomerular capillary pressure and the glomerular filtration rate decreased. There is less blood that is able to enter the glomerulus because of reduced radius of afferent arteriole, therefore the pressure and filtration rate are also reduced. 5. Describe the effect of increasing the afferent arteriole radius on glomerular capillary pressure and filtration rate. How well did the results compare with your prediction? Your answer: The Glomerular capillary pressure and glomerular filtration rate both increased when the radius of the afferent arteriole was increased. There was more perfusion into the renal corpuscle. Describe the effect of decreasing the efferent arteriole radius on glomerular capillary pressure and filtration rate. How well did the results compare with your prediction? Your answer: Decreasing the radius of the efferent arteriole caused an increase in glomerular capillary pressure and glomerular filtration rate. 7. Describe the effect of increasing the efferent radius on glomerular capillary pressure and filtration rate. Your answer: Increasing the efferent arteriole radius causes the glomerular capillary pressure and glomerular filtration rate to decrease.
