Which of the following hormones increases blood calcium levels?a. calcitonin b. thyroxine (T4)c. parathyroid hormone d. mineralocorticoid
A tumour on the parathyroid glands will result in excessive production of parathyroid hormone (PTH) called hyperparathyroidism. PTH has a significant role in calcium homeostasis. Hyperparathyroidism will result in all the following EXCEPT
Select one:
a. the increase in blood calcium levels
b. the breakdown of bones and teeth to release calcium into the blood
c. the deposition of calcium into bones and teeth, making them strong and healthy
d. the increase in absorption of calcium ions by kidney nephrons, leading to kidney stones
