Biology Question on Human Endocrine System
The blood calcium level is lowered by the deficiency of
A
Both calcitonin and parathormone
B
Calcitonin
C
Parathormone
D
Thyroxine
Answer
Parathormone
Explanation
Solution
This is due to the deficiency of parathormone and is also called parathyroid hormone. It is produced by the parathyroid glands that are located in the neck near the thyroid gland. This hormone helps in the role of regulating the levels of calcium and phosphate in the blood. If the calcium level is low in the blood, more parathormone is released into the bloodstream. They maintain the level of calcium by bone resorption, increasing the absorption of calcium from the intestine and decreasing the level of calcium that is excreted.
