The action of parathyroid hormone

ActionofPTH1.jpg

The release of calcium from the bone (resorption) and its absorption from the small intestine transfers calcium into the blood. This will raise blood calcium concentration. The excretion of calcium by the kidney and its storage (deposition) in bone will transfer calcium out of the blood. This will decrease blood calcium concentration.
