Which hormones are secreted by the thyroid gland?

Explanation:
The thyroid gland produces hormones that set the body’s metabolic rate and help regulate calcium levels in the blood. Follicular cells make thyroid hormones T3 and T4, which speed up metabolism, influence heat production, and support growth and development. Parafollicular (C) cells release calcitonin, which lowers blood calcium by inhibiting bone breakdown and promoting calcium deposition in bone. The other hormones mentioned aren’t produced by the thyroid: epinephrine and norepinephrine come from the adrenal medulla, and parathyroid hormone comes from the parathyroid glands. So, the thyroid secretes T3, T4, and calcitonin.
