Quizplus · Accepted Answer

Parathyroid hormone (PTH) is responsible for blood calcium regulation. It increases blood calcium levels by stimulating bone breakdown and calcium release, while also decreasing calcium excretion from the kidneys. In cases of low blood calcium levels, PTH is released to help maintain appropriate levels. In osteoporosis, there is a decreased bone density due to increased bone breakdown and decreased new bone formation, often as a result of imbalances in PTH and other hormones.
