5 True/False questions

  1. aThe myogenic mechanism of autoregulation that occurs within afferent arterioles of the kidney is an __________ control of GFR.


  2. aBoth the proximal convoluted tubule and the distal convoluted tubule reside in the cortex of the kidney.


  3. bFluid contained within the lumen of a nephron loop would be considered to be:
    tubular fluid.


  4. bIf there is an increase in systemic blood pressure, the resulting stretch of afferent arterioles results in reflexive:
    vasoconstriction of efferent arterioles to raise GFR.
    vasoconstriction of afferent arterioles to keep GFR normal.
    vasodilation of efferent arterioles to lower GFR.
    vasodilation of afferent arterioles to keep GFR normal.


  5. b
    This figure shows a frontal section of the kidney. Which number(s) indicate a renal papilla?
    2, 7
