In tubuloglomerular feedback, an increase in glomerular filtration rate would increase the______ , thereby stimulating the release of a paracrine factor from the macula densa that would______
A) flow of tubular fluid : constrict the efferent arteriole
B) afferent arteriolar pressure : constrict the afferent arteriole
C) afferent arteriolar pressure : increase filtrate flow
D) flow of tubular fluid : constrict the afferent arteriole
E) flow of tubular fluid : dilate the afferent arteriole

Question

Quizplus · Accepted Answer

An increase in glomerular filtration rate increases the flow of tubular fluid, which is sensed by the macula densa. In response, the macula densa releases paracrine factors that constrict the afferent arteriole to reduce glomerular filtration rate and restore balance.
