text: Yo, check it out, this review's about
  The metabolism and homeostasis no doubt
  Of calcium and phosphorus, let's dive in deep
  Talkin' 'bout the kinetics and how they creep
  
  We discuss the distribution, where calcium goes
  Theories of calculus formation, flows
  Hypercalcemia, hypocalcemia, we break it down
  Parathyroid hormone, thyrocalcitonin, hold the crown
  
  1,25 dihydroxy Vitamin D(3), keepin' it real
  Maintaining calcium levels, gotta seal the deal
  Skeletal integrity, we gotta mention that
  These factors play a role, that's a solid fact
  
  Enzyme activation, inhibition, what's the connection?
  Calcium's involved, it's a vital section
  Muscle and nerve function, they rely on this
  Intracellular metabolism, can't dismiss
  
  So this review's got it all, no room for debate
  Calcium and phosphorus, they regulate
  Metabolism and homeostasis, they're in control
  Keepin' our bodies running, that's the ultimate goal
