A person has problems with calcium absorption in his body. Which one of the following glands may not be functioning properly?
Parathyroid
The parathyroid gland secretes a hormone called parathormone. The function of this hormone is to raise the level of calcium in the blood. When the level of calcium in the blood decreases, it reabsorbs calcium to the blood from the kidneys and prevents the deposition of calcium in bones.
The thymus gland secretes thymosin. Pancreas regulates the blood sugar level by secreting insulin and glucagon. The parotid glands are salivary glands that secrete saliva.
