<prompt> Which change tends to increase GFR?Increased afferent aeriolar resistanceDecreased efferent aeriolar resistanceIncreased glomerular capillary filtration coefficientIncreased Bowmans capsule hydrostatic pressure  <response>: Glomerular capillary filtration coefficient hydraulic conductivity x surface area of the glomerular capillaries. Therefore, increasing the glomerular capillary filtration coefficient tends to increase GFR. Increased afferent aeriolar resistance, decreased efferent aeriolar resistance, increased Bowmans capsule hydrostatic pressure, and decreased glomerular hydrostatic pressure tend to decrease GFR.
