Question

question 1 which two hormones work in opposition of each other to regulate blood calcium levels? answer pth and calcitonin calcitonin and calcitriol pth and calcitriol i dont know yet

Explanation:

Parathyroid hormone (PTH) increases blood - calcium levels by promoting calcium release from bones, enhancing calcium reabsorption in the kidneys, and stimulating activation of vitamin D. Calcitonin, on the other hand, decreases blood - calcium levels by inhibiting bone resorption and promoting calcium deposition in bones. Calcitriol (active form of vitamin D) works with PTH to increase calcium levels, not in opposition to PTH or calcitonin.

Answer:

PTH and calcitonin
