Hypercalcemic hormone is
A. Aldosterone
B. Calcitriol
C. PTH
D. TCT

Hint: Our body metabolism sometimes starts to malfunction by overproduction of something or reducing the production. It happens due to a change in the functioning of a hormone or protein. They can be treated by observing their increase or decrease because, in our body, everything has to maintain a balance.

Complete answer:
Hormones are the proteins performing a particular function. They are the chemicals which will affect a particular system in the body. The can be released directly into the blood by endocrine glands or through tubes by the exocrine glands.

> Option A: Aldosterone: It is present for stimulating the renal absorption of sodium ions and water. This helps to regulate the blood volume in the kidneys.

> Option B: Calcitriol: It is produced in the kidney and is a form of vitamin D. It is used to treat the low calcium levels by providing the right amount of calcium to the patient.

> Option C: PTH: PTH is the parathormone of the parathyroid gland. It will reduce the phosphate level in blood and reverse increase the level of calcium in the blood. Thus, the increased amount of calcium makes the blood hypercalcemia.

> Option D: TCT: TCT is also called calcitonin. Its work is to reduce the calcium level in the blood by reducing the number and activity of osteoblasts.

Hence, the correct answer is option (C).

Note: Parathyrin is the other name for PTH. It maintains the serum calcium level by affecting the kidney, bone and intestine. It is released by the parathyroid gland. It is one of the most important hormones. It is released by the epithelial tissue of the posterior surface of the thyroid gland.
