What will happen if the glomerular filtration rate is too low?
a. blood volume will decrease
b. the body will lose too much water
c. wastes will build up in the blood
d. the body will lose too many electrolytes

c. Wastes will build up in the blood  

Explanation:

Glomerular filtration rate is a measure of renal function that can be calculated from a simple blood test that measures blood creatinine levels and takes into account age, ethnicity, gender and other factors. Through the glomerular filtration rate, your doctor can determine the stage of kidney disease and plan treatment. The lower the GFR, the more severe the renal failure.

Since kidney failure is the slow loss of kidney function, its main function is to remove waste and excess water from the body. We can conclude that if the glomerular filtration rate is too low, debris will accumulate in the blood.
