Answer:

Parathyroid hormone- Raise blood calcium level
Explanation:
The thyroid gland is an endocrine gland which secrete its hormone in the blood directly. Both calcitonin and parathyroid hormone are released by the thyroid gland. Parathyroid hormone is released when the blood calcium level is low.
Parathyroid hormone increases the blood calcium level by osteoclast stimulation which releases calcium from bones and increases blood calcium level. Calcitonin is antagonistic to parathyroid hormone and it reduce the blood calcium level in the blood by stimulating the activity of osteoblast.
