63. An increase in which of the following would cause the glomerular filtration

ID: 3524654 • Letter: 6

Question

63. An increase in which of the following would cause the glomerular filtration rate (GFR) to increase? a. blood colloid osmotic pressure (BCOP) b. glomerular hydrostatic pressure (GHP) c. diameter of efferent arteriole d. length of the nephron loop e. capsular hydrostatic pressure (CsHP) 64. If the glomerular filtration rate (GFR) decreases from 120 m/min to 50 ml/min, how will the sodium chloride concentration of the filtrate be affected? a. increase in NaCI concentration b. decrease in NaCl concentration c. no change in NaCI concentration

Explanation / Answer

Answer

63) Glomerular hydrostatic pressure would cause the GFR to increase.
-  It is the pressure exerted by fluid on the capillary walls of the glomerulus.
Option B

64) If the GFT decreases from 120ml/min to 50ml/min the sodium cloride concentration will decrease in the filterate.
- As the GFR is high there is not musch time for NaCl to get reabsorbed. But in low GFR, NaCl will be reabsorped in more amount, resulting in decreased NaCl concentration in the filterate.
Option B ) decrease in NaCl concentration
