Question

The MACULA DENSA acts to keep the GFR fairly stable over a wide range of blood pressures.

It responds to NaCl concentrations in the early part of the distal tubule/ end of the ascending

limb of the loop of Henle. Abnormally high NaCl concentrations suggest a ________________ GFR and the macula densa will signal the afferent arterioles to __________________. Abnormally low NaCl concentrations suggest a ________________ GFR and the macula densa will signal the afferent arterioles to__________________.

2) The MYOGENIC RESPONSE will also act to keep GFR fairly stable. As blood pressure

increases, the depolarization of stretch receptors causes the afferent arterioles to

_____________________; this causes a _____________________ in the capillary hydrostatic pressure in

the glomerulus, ____________________ -ing GFR.

3) The GRANULAR CELLS will release RENIN in response to: ___________ in blood pressure, ___________ in blood volume, and/or ___________ in flow through the macula densa.

Answer 1
