Quizplus · Accepted Answer

Parathyroid hormone stimulates the activity of osteoclasts, which are responsible for breaking down bone tissue and releasing calcium into the bloodstream. It also increases the rate of calcium reabsorption in the kidney tubules, which helps to maintain calcium homeostasis in the body. This process is mediated by the hormone's interaction with the parathyroid hormone receptor in target cells.
