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

Question

Quizplus · Accepted Answer

The macula densa cells detect changes in sodium chloride concentration in the distal tubule, which reflects changes in glomerular hydrostatic pressure (GHP), and they help regulate it to maintain proper glomerular filtration rate (GFR).
