Solution
The correct option is E calcitonin Parathormone is secreted by the parathyroid gland. It increases the blood calcium levels by increasing the reabsorption of calcium from kidneys and decreasing calcium deposition on bones.
Calcitonin, secreted by thyroid gland decreases the blood calcium level by increasing bone absorption of calcium.
They work together to regulate the blood calcium levels.

- Prevents the process of mixing of calcium from bones to blood.
- Stores the excess calcium from blood to bones.
