5 True/False questions
c → Sympathetic stimulation causes:
mesangial cells to release angiotensin, which ultimately leads to granular cell contraction.
mesangial cells to release angiotensin, which ultimately leads to granular cell relaxation.
granular cells to release renin, which ultimately leads to mesangial cell contraction.
granular cells to release renin, which ultimately leads to mesangial cell relaxation.
inhibited release of erythropoietin and contraction of granular and mesangial cells.
c → Careful measurements of GFR are made by injection of _______, but approximations of GFR can be made more simply by measuring renal plasma clearance of _________.
creatine phosphate, insulin
insulin, creatine phosphate
e → 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.
e → The myogenic mechanism of autoregulation that occurs within afferent arterioles of the kidney is an __________ control of GFR.
This figure shows a frontal section of the kidney. What structure does number 5 indicate?
