What do the macula densa cells regulate in their role as part of the tubuloglomerular feedback loop?
A)changes in renal clearance
B)changes in glomerular hydrostatic pressure (GHP)
C)changes in blood pH
D)changes in the glomerular colloid osmotic pressure (GCOP)

Question

Quizplus · Accepted Answer

Macula densa cells regulate changes in glomerular hydrostatic pressure (GHP) as part of the tubuloglomerular feedback loop. These cells respond to changes in the sodium chloride concentration in the distal tubule by releasing vasoactive substances that affect the afferent arteriole and regulate GHP.
