5 of 7
which hormone helps increase blood calcium levels by stimulating bone resorption?
parathyroid hormone (pth)
insulin
calcitonin
growth hormone

Explanation:

Parathyroid hormone (PTH) stimulates osteoclasts to break down bone tissue, releasing calcium into the bloodstream. Insulin regulates blood - glucose levels. Calcitonin decreases blood calcium levels by inhibiting bone resorption. Growth hormone is involved in growth and metabolism but not in directly increasing blood calcium via bone resorption.

Answer:

Parathyroid hormone (PTH)
