Answer 2

Step-by-step explanation:

Thyroid releases hormone known as calcitonin which is responsible for regulating calcium through involvement in calcium metabolism. The parafollicular cells (also known as C- cells) of the thyroid gland produces calcitonin hormone which regulate the level of both calcium and phosphate with in the blood.

Calcitonin increase the level of calcium in blood by opposing the effect of parathyroid hormone (PTH)
