- a The tubuloglomerular feedback mechanism responds to an increase in:
systemic blood pressure by signaling for a decrease in heart rate through blood-borne hormones.
urine production by signaling for a decrease in urine production through the hormone ADH.
NaCl concentration in tubular fluid by signaling for afferent arteriole constriction with local chemical messengers.
glomerular capillary hydrostatic pressure by signaling for afferent arterioles to constrict and increase filtration rate.
