The thyroid gland has certain cells known as parafollicular cells (AKA C cells) that secrete a hormone known as calcitonin that can decrease blood calcium levels.
Thyroid Glands
thyroid gland
The hormone calcitonin acts to reduce blood calcium
Glands produce hormones
adrenal glands
"The amount of calcium in the blood is regulated by two organs: thyroid and parathyroid glands. Each gland produces hormones by sensing the amount of calcium in the blood. When calcium is high in the blood, the thyroid gland produces calcitonin, which results in the removal of excess calcium from the blood. When calcium is low in the blood, the parathyroid gland produces parathyroid hormone, which causes the release of calcium from bone into the blood."
The adrenal glands in a pig produces hormones for water balance, stress hormones, and androgens. They also secrete fight or flight hormones.
Parathyroid glands secrete PTH (parathyroid hormone) to regulate blood calcium levels.
Thyroid and Parathyroid Glands are Antagonistic. -Thyroid gland produces Calcitonin, which lowers blood calcium levels. -Parathyroid gland produces Parathyroid Hormone (PTH), which raises blood calcium levels. There are very many "antagonistic" hormones that are produced by endocrine glands.
Glands
it is in the endocrine system because it produces hormones
tyroid gland, paratyroid glands
The pituitary gland
Adrenal glands produces four type of hormones: Catecholamine, Aldosterone, Cortisol and Androgens like Testosterone.
