A normal urine sample contains only chloride molecules, but not glucose or albumin molecules. What does this?
Filtration. The question is asking what does the kidney do that allows the urine to not contain any albumin or glucose. It simply acts as a filter, selecting what is to be passed into urine and what is not. Just a few errors from what i see witten below. The question does not say that albumin and glucose are occurring in the urine read it closely. Also glucose is not “too big” to pass into urine, it is just completely reabsorbed.
