Tubuloglomerular feedback is primarily triggered by which of the following?

Show Answers

Release of ADH in the collecting ductSteady concentration of solutes reaching the distal tubuleActivity of the macula densa cellsEquilibrium between the ascending and descending limbs of the loop of HenleFiltration rate in the proximal tubule

Explanation

Tubuloglomerular feedback is a mechanism that responds to the consistent solute concentration delivered to the distal tubule, helping regulate glomerular filtration rate. This process is distinct from ADH secretion, macula densa cell activity, or the balance between different segments of the loop of Henle.
