, 14. Answer the following question. Explain in detail how PTH and calcitonin work to
maintain calcium balance. - CORRECT ANSWER: Calcitonin: produced by the thyroid
glands, deposits calcium into bone. Calcitonin opposes the ac!on of PTH. When the
blood calcium level reaches the appropriate level through all these means, the
parathyroid glands stop producing PTH through nega!ve feedback. PTH: produced by
the parathyroid glands increase the amount of calcium in the blood. (Any one of the
following explana!ons of PTH is acceptable) PTH s!mulates the increased absorp!on of
calcium from the intes!nes. PTH retains calcium through excre!ng phosphate at the
kidneys. In the bones, PTH promotes the ac!vity of osteoclasts to demineralize of the
bone, increasing the amount of calcium in the blood.
14. Explain why it would be harmful to have an increased secretion of ACTH in
someone who is diabetic. - CORRECT ANSWER: ACTH controls the secretion of
cortisol from the adrenal cortex. Increased levels of ACTH would cause increased levels
of cortisol within the blood. Cortisol increases blood glucose levels which will decrease
the effectiveness of insulin treatments.
