TABLE 9-3 PARATHYROID HORMONE

This table identifies parathyroid hormone along with its target organs and functions and associated
disorders.

Hormone Target Organ and Functions Disorder

Parathyroid hormone (PTH) • Bones—increases reabsorption of calcium
and phosphate from bone to blood

• Kidneys—increases calcium absorption
  and phosphate excretion


• Small intestine—increases absorption of
  calcium and phosphate
  
  
  • Hyposecretion causes tetany.
  
  
  • Hypersecretion causes osteitis
    fibrosa cystica.
