Hormones secreted by the parathyroid

The only hormone secreted by this gland is called parathormone.

Function of the parathyroid gland

One of the major function of the parathyroid gland is it controls the level of calcium content in the blood
The parathyroid glands produce parathyroid hormone. This hormone helps maintain an appropriate balance of calcium in the bloodstream and in tissues that depend on calcium for proper function

Effects and consequences malfunctioning parathyroid

Parathyroid hormone helps prevent low calcium levels by acting on the bones, intestine, and kidneys. In the bones, the hormone triggers the release of calcium stores from the bones to the blood. This can lead to bone destruction. In the intestines, parathyroid hormone helps with vitamin D metabolism”


As Mr. Kola Balogun employs one labour to work on his one hectare farm, 10 tons of yam were produced. As more and more labour are employed in every successive round of production, the total output continues to increase from 10 to 30, to 60, to 120 and so on. But as the fifth (5th) labour was used or employed, there was a drop in production from 120 to 100. This is the stage at which the law of diminishing returns sets in as every additional unit of labour brings about a decrease in the total output
