Which of the following is not the function of parathormone (PTH)?
- AIncreases calcium level in blood
- Correct answerBDecreases the reabsorption of calcium from the renal tubules
- CIncreases the calcium absorption from GIT
- DDecreases the movement of calcium to bones.
Solution
Functions of the parathyroid hormone (PTH) includes:
A. PTH increases the process of bone resorption or dissolution (demineralization) of bone.
B. PTH stimulates the reabsorption of Ca2+ by the renal tubules.
C. PTH increases the absorption of Ca2+ from digested food.
D. All of the above actions of PTH increase the blood Ca2+ levels, thus PTH is a hypercalcemic hormone. PTH and Thyrocalcitonin play a significant role in maintaining the calcium balance in the body.
