Jasmine has high blood pressure and an increased glomerular filtration rate (GFR).How does the tubuloglomerular feedback mechanism restore normal pressure in her glomerulus?
A)The juxtaglomerular (JG)cells increase production of renin.
B)The juxtaglomerular (JG)cells decrease production of renin.
C)The efferent arteriole constricts.
D)The afferent arteriole vasodilates.

Question

Quizplus · Accepted Answer

The tubuloglomerular feedback mechanism involves the detection of increased sodium chloride (NaCl) concentration by the macula densa cells due to the increased GFR. In response, the juxtaglomerular (JG) cells decrease the production of renin, which leads to adjustments in arteriole tone and a decrease in GFR, helping to restore normal pressure in the glomerulus.
