The tubuloglomerular feedback is mediated by:
High-Yield Explanation
C i.e. Sensing NaC1 concentration in the macula densa'To perform the function of auto regulation, the kidneys have a feed back mechanism (tubuloglomerular feed back) that links changes in sodium chloride concentration at the macula densa (tubular component) with the control of renal aeriolar resistance. (glomerular component).
