The glomerular filtration rate (GFR) is directly related to the:
 
  a. perfusion pressure in the glomerular capil-laries.
  b. oncotic pressure in the glomerular capillar-ies.
  c. vascular resistance in the glomerular arte-rioles.
  d. hydrostatic pressure in the Bowman's capsule.

Question 2

The renin-angiotensin system will be activated by:
 
  a. increased blood volume.
  b. elevated sodium concentrations.
  c. decreased blood pressure in the afferent arterioles.
  d. renal hypertension.

Answer to Question 1

ANS: A
The filtration of the plasma per unit of time is known as the GFR, which is directly related to the perfusion pressure of the glomerular capillaries. The filtration of the plasma per unit of time is not associated with the oncotic pressure of the glomerular capillaries, the vascular resistance in the glomerular arterioles, or the hydrostatic pressure in the Bowman's capsule.

Answer to Question 2

ANS: C
The renin-angiotensin system is activated by decreased blood pressure. Activation of the ren-in-angiotensin system is not associated with the increased blood volume, elevated sodium levels, or renal hypertension.
