1. Why are blood cells and proteins not a normal constituent ofurine?
2. What happens if the TM for glucose is exceeded in thePCT?
3. Where in the urinary tract (not kidneys) would the followingshed cells have originated?
Squamous (more common):
Transitional:
4. The specific gravity of pure water is 1.000. Urine SpecificGravities range from 1.001-1.035. With regards to the solute, howdoes urine with a specific gravity of 1.006 differ from urine witha specific gravity of 1.024?
5. Casts are formed in the collecting duct and can be acellularor cellular. When filtrate flow is low, proteins and cellsaccumulated and concentrated in the tubules. When the flowincreases the casts are pushed out of the tubules.
Decreased urine pH contributes to the formation of casts.Explain why a decreased filtrate pH promotes cast formation.
