Problem
I. Briefly describe the extrinsic regulation of GFR that would allow the body to restore GFR after:
i. a drop in blood pressure and
ii. following consumption of an excess NaCl load.
II. Briefly describe the physiological mechanisms that allow the body to restore homeostasis following consumption of excess water load.
III. The kidneys alter urine production in response to changes in plasma osmolarity and volume. A small (physiological) change in which of these two parameters (plasma osmolarity or plasma volume) will lead to a change in urine production? Use the data from the practical class to explain how you reached this conclusion.
