Parathyroid hormone

Vedclass · Answer

(A) Parathyroid hormone $(PTH)$ is secreted by the parathyroid glands. $PTH$ is a hypercalcemic hormone,meaning it increases the level of calcium ions $(Ca^{2+})$ in the blood. It achieves this by stimulating the process of bone resorption (dissolution/demineralization) by osteoclasts,which releases calcium into the blood. It also promotes the reabsorption of calcium by the renal tubules and increases calcium absorption from the digested food in the intestine. Therefore,the hyposecretion (under-secretion) of $PTH$ leads to a decrease in blood calcium levels,which can cause tetany (sustained muscle contractions). Conversely,calcitonin is a hypocalcemic hormone that lowers blood calcium levels.
