Question 1 Multiple Choice 0.5 points Which one of the following statements is false? The hydrostatic pressure (=blood pressure) in the glomerular capillaries is greater than the osmotic pressure exerted by proteins and other solutes in the plasma within the glomerular capillaries. If the osmotic pressure exerted by solutes in the peritubular capillaries is greater than the blood pressure in those capillaries, then water will be reabsorbed. Constriction of the afferent arteriole is likely to reduce the volume of filtrate appearing in Bowman’s capsule. Endothelial cells in glomerular capillaries are sealed to one another by numerous tight junctions. Question 2 Multiple Choice 0.5 points Your doctor calls with the results of your urinalysis and tells you that they found proteinuria, the presence of abnormal amounts of protein in your urine sample. What could have caused this? Glomerulonephritis (inflammation of glomeruli) due to localized damage there. Abnormal active transport of protein in Bowman’s capsule.
