What chemical causes a decrease in the blood calcium level?

Answer 1

The hormone produced by the para follicular cells of the thyroid

gland is calcitonin (CT).

CT can decrease the level of calcium in the blood by inhibiting

the action of osteoclasts, the cells that break down bone extracellular

matrix. The secretion of CT is controlled by a negative

feedback system.

When its blood level is high,calcitonin lowers the amount of

blood calcium and phosphates by inhibiting bone resorption

(breakdown of bone extracellular matrix) by osteoclasts and by

accelerating uptake of calcium and phosphates into bone extracellular

matrix.

Answer 2

The parathyroid glands (4 of them) secrete parathyroid hormone to increase blood calcium. When the parathyroid glands detect low blood calcium levels, they secrete more parathyroid hormone, which causes the bones to release calcium to the bloodstream, thereby increasing blood calcium levels.

Answer 3

Calcitonin is a hormone that can cause a decrease in blood calcium levels by promoting its uptake and storage in bones. It works in opposition to parathyroid hormone, which increases blood calcium levels.

Answer 4

Calcitonin is the thyroid hormone that decreases blood calcium concentration.

Answer 5

calcitonin

Answer 6

Calcitonin
