PSIO 202 Exam 3 1. Sometimes kidney stones block the ureter. This would prevent the flow of urine into the _________ . a) collecting duct b) renal pyramid c) interstitial fluid d) urinary bladder e) calyx 2. How can you distinguish between cortical and juxtamedullary nephrons? a) the presence of intercalated cells and principal cells in juxtamedullary nephrons b) vasa recta and long loops of Henle in juxtamedullary nephrons c) the lack of a juxtaglomerular apparatus in cortical nephrons d) increased number of pedicels on podocytes in cortical nephrons e) the juxtamedullary nephrons are close to, but do not enter, the medulla 3. The Renal Corpuscle includes the _____________________. a) proximal and distal convoluted tubules b) ascending and descending loops of Henle c) cortex and medulla d) mucosa and submucosa e) Bowman’s capsule and glomerular capillaries 4. Microvilli are found on epithelial cells that make up the walls of the proximal convoluted tubule. If there were no microvilli, how would kidney function be affected? a) the net filtration pressure would be reduced. b) there would be fewer pedicels and hence less protein reabsorption c) the surface area of the apical membrane would be reduced, so reabsorption would decrease. d) more glucose could be returned to the circulatory system e) there could be no facultative water reabsorption 5. A patient has a large amount of protein in the urine. This may reflect compromised function of ____________. a) juxtaglomerular cells b) podocytes c) principal cells d) intercalated cells e) goblet cells 6. Loss of the osmotic gradient within the interstitial fluid of the renal medulla would _________ a) allow protein to appear in the urine b) compromise the ability of the kidneys to regulate blood pressure c) interfere with filtration d) improve the ability of the kidneys to regulate blood volume e) deflate Bowman’s capsule 7. Which of the following is NOT involved in filtration within the kidney? a) fenestrations in the endothelium of the glomerular capillaries

PSIO 202 Exam 3 b) the basement membrane surrounding the glomerular capillaries c) filtration slits between the pedicels of the podocytes d) the blood pressure in the afferent arterioles is greater than that within the efferent arterioles e) principal cells 8. The renal Glomerular Blood Hydrostatic Pressure (GBHP) ________________________. a) is the osmotic pressure from proteins in the nephron b) pushes fluid into the glomerular capillaries c) resists filtration d) is a positive pressure that pushes fluid into the capsular space. e) has a negligible influence on the net filtration pressure 9. The net filtration pressure is so dependent upon healthy blood pressure because _________________. a)
