Question

Quizplus · Accepted Answer

Parathyroid hormone (PTH) plays a crucial role in calcium homeostasis by increasing blood calcium levels. It does so by stimulating osteoclast activity (not osteoblasts), increasing calcium absorption in the kidneys and intestines, and indirectly inhibiting calcitonin secretion, which would otherwise lower blood calcium levels.
