At high levels of efferent arteriole constriction will occur. We will lower RPF and increase GFR due to less renal blood flow and more na/h2o filtration. The GFR is balanced out by the na/h2o reabsorbtion and send less fluid into the urine. GFR WILL go up but it will not cause more na/h2o to be excreted since A2 increases Na and H exchange and water follows as well as the capillary effect. This can be explained from the B&B video at 6min (https://www.boardsbeyond.com/video/step-1-p/renal-endocrinology) as well as in FA 2023 on page 605.
Please resubmit with an accepted source. We currently only accept FA24, not FA23. B&B is not an accepted source.
