Exercise 9: Renal System Physiology: Activity 3: Renal Response to Altered Blood Pressure Lab Report Pre-lab Quiz Results You scored 25% by answering 1 out of 4 questions correctly. 1. If all other variables are kept constant, how does the afferent arteriole radius affect the rate of glomerular filtration (select all that apply)? Your answer : b. A decreased afferent arteriole radius will increase the rate of glomerular filtration. Correct answer: c. An increased afferent arteriole radius will increase the rate of glomerular filtration. d. A decreased afferent arteriole radius will decrease the rate of glomerular filtration. 2. If all other variables are kept constant, how does the efferent arteriole radius affect the rate of glomerular filtration (select all that apply)? Your answer : d. A decreased efferent arteriole radius will decrease the rate of glomerular filtration. Correct answer: a. An increased efferent arteriole radius will decrease the rate of glomerular filtration. b. A decreased efferent arteriole radius will increase the rate of glomerular filtration. 3. If all other variables are kept constant, how does blood pressure affect the rate of glomerular filtration (select all that apply)? Your answer : c. If blood pressure goes down, the rate of glomerular filtration goes up. Correct answer: b. If blood pressure goes up, the rate of glomerular filtration goes up. d. If blood pressure goes down, the rate of glomerular filtration goes down. 4. In the absence of other renal processes (including tubular reabsorption and secretion), more glomerular filtration leads to a larger urine volume. You correctly answered: a. true
