B)negative feedback control
C)positive feedback control

Question

Quizplus · Accepted Answer

Negative feedback control is the mechanism by which the release of a hormone to lower blood calcium levels when it gets too high is regulated. This is because when blood calcium levels are too high, the parathyroid glands release parathyroid hormone (PTH), which stimulates the release of calcium from bones and promotes the reabsorption of calcium in the kidneys, ultimately lowering blood calcium levels. As blood calcium levels return to normal, PTH secretion is inhibited, thus demonstrating negative feedback control.
