Tomas had low levels of calcium in his body. Vitamin D is essential in maintaining a calcium balance. He started taking vitamin D supplements. Because Tomas took high doses of vitamin D, the calcium levels in his body increased. Which endocrine glands will help maintain homeostasis by regulating the increased calcium levels? ovary, pancreas, thyroid, parathyroid, testicle, or adrenal gland

Answer 1

The endocrine glands that will help maintain homeostasis by regulating the increased calcium levels are the parathyroid gland and the thyroid gland. The parathyroid gland produces parathyroid hormone (PTH), which increases calcium levels in the blood by stimulating the release of calcium from bones and increasing the absorption of calcium in the intestines. The thyroid gland produces calcitonin, which helps decrease calcium levels in the blood by inhibiting the release of calcium from bones and increasing the excretion of calcium in the kidneys.
