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?

Answer 1

The endocrine glands that will help maintain homeostasis by regulating the increased calcium levels are the parathyroid glands and the thyroid gland. The parathyroid glands produce parathyroid hormone (PTH), which increases calcium levels by promoting its release from bones and enhancing its absorption from the intestine and reabsorption from the kidneys. The thyroid gland produces calcitonin, which helps lower blood calcium levels by decreasing its release from bones and increasing its excretion from the kidneys. Together, these glands work to regulate the calcium balance in the body.
