I teach A&P and we read that a diet too high in protein causes calcium 
depletion.  I found that the calcium is excreted with the nitrogenous 
waste in urine but I can't figure out why.  I understand that urea is a 
result of protein breakdown, but how does this affect the calcium levels?  
What's the biochemistry of this?
