Then adjust numbers in the equation to determine if there is an increase, decrease, or no change to the net filtration rate). Group of answer choices A) Blood colloid osmotic pressure would be decreased, increasing the net glomerular filtration rate. B) Blood colloid osmotic pressure would be decreased, decreasing the net glomerular filtration rate.
