The Digestive, Respiratory, and Urinary Systems
All of the following substances would be found in the glomerular filtrate of the nephron before reabsorption except:

All relatively small molecules initially enter the filtrate, even if they are nutrients; plasma proteins are too large to diffuse across the capillary wall. Glucose and amino acids will normally be completely reabsorbed, leaving urea to be excreted in the urine.
