Less afferent a. resistance leads to....

- increased blood flow, which leads to....
- LESS GFR (because if blood is moving faster, it is harder to filter. For example, if water is moving thru a pipe with holes in it, much less water will drip through the holes if the water is moving faster).
- since FF = GFR/RBF, and GFR just decrased, FF will decrease

hope this helped.
