Textbook Question
Chapter 15, Problem 6AWK
A possible complication of a strep throat infection is post-streptococcal glomerulonephritis, in this disease, antibodies produced against the streptococcus invader also cause inflammation of glomeruli in the kidneys and damage to the glomerular filtration barrier. What might be the symptoms of damage to the glomerular filtration barrier, and what effect would you expect this to have on kidney function?

Which one of the following statements is false?a. Blood pressure in the glomerular capillaries is greater than the osmotic pressure exerted by proteins in the plasma within the glomerular capillaries.b. 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.c. Endothelial cells in glomerular capillaries are highly permeable, facilitating filtration of fluid into Bowman’s capsule.d. Constriction of the afferent arteriole is likely to reduce the volume of filtrate appearing in Bowman’s capsule.e. The efferent arteriole carries blood from the glomerular capillaries directly to the renal vein.0.5 pointsQuestion 2Your 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?a. Infection and inflammation in the kidney.b. Abnormally high concentration of plasma…
Several pharmacological agents have been shown to lower the pressure of the filtrate inside the lumen of nephrons. What affect will this have?
a
hydrostatic pressure of fluid in the Bowman’s capsule increases, GFR increases
b
hydrostatic pressure of fluid in the Bowman’s capsule decreases, GFR decreases
c
hydrostatic pressure of fluid in the Bowman’s capsule increases, GFR decreases
d
hydrostatic pressure of fluid in the Bowman’s capsule decreases, GFR increases
Fred was diagnosed 6 months ago with liver cancer. His liver is no longer able to make the necessary amount of proteins needed by the body. What effect, if any, would this have on the net glomerular filtration rate?
(Hint, decide which of the 3 forces contributing to the net filtration rate is affected. Then adjust numbers in the equation to determine if there is an increase, decrease, or no change to the net filtration rate).
Group of answer choices
A) Blood colloid osmotic pressure would be decreased, increasing the net glomerular filtration rate.
B) Blood colloid osmotic pressure would be decreased, decreasing the net glomerular filtration rate.
C) Capsular hydrostatic pressure would be decreased, increasing the net glomerular filtration rate.
D) Capsular hydrostatic pressure would be decreased, decreasing the net glomerular filtration rate.
E) There would be no effect on the net glomerular filtration rate.
