Explanation:
Detailed explanation-1: -When the blood calcium levels are low, the osteoclasts breakdown bone tissues, and the calcium ions are released from bone into the blood. Thus, due to the movement of calcium ions from bone into the blood, the blood calcium levels increase.
Detailed explanation-2: -Parathyroid hormone is directly involved in the bones, kidneys, and small intestine. In the bones, PTH stimulates the release of calcium in an indirect process through osteoclasts which ultimately leads to the resorption of the bones.
