What is the normal volume of urine excreted in a 24-hour period? - Answer- 0.8-2.0
liters
Assuming normal conditions, note whether each of the following substances would be in
greater relative concentration in the urine than in the glomerular filtrate. - Answer-
Phosphate ions, sulfate ions, potassium ions, urea, uric acid, creatinine.
Assuming normal conditions, note whether each of the following substances would be in
lesser concentration in the urine than in the glomerular filtrate. - Answer- Water, sodium
ions, amino acids, glucose.
Assuming normal conditions, note whether each of the following substances would be

found in distilled water and add to the density of the sample.
Explain the relationship between the color, specific gravity, and volume of urine. -
Answer- Generally, the smaller the volume, the greater the specific gravity (more
solutes/volume) and the deeper the color.
Name three constituents that might be present if a urinary tract infection exists. -
Answer- WBCs (pus), RBCs, and casts.
How does a urinary tract infection influence urine pH? - Answer- Becomes alkaline
