Summary Introduction
Introduction :
The hormone that helps to regulate blood calcium levels is calcitonin. In response to high blood calcium levels, the thyroid gland specifically, its parafollicular cells releases calcitonin. Calcitonin inhibits osteoclast activity primarily. Furthermore, calcitonin stimulates the kidneys to increase calcium loss in the urine. As a result, blood calcium levels decrease.

Students have asked these similar questions
Draw a negative feedback loop for blood calcium regulation.
Falling calcium level signals release of parathyroid hormone from the parathyroid glands. Calcium is released from bones, increased uptake by digestive system.
Rising calcium level signals release of calcitonin from the thyroid. Blood calcium is taken up into bone tissue.
How does Parathyroid Hormone elevate blood calcium levels?
by increasing the amount of CA2+ removed from the blood by the kidneys
by decreasing the amount of CA2+ absorbed from the gut into the blood
by increasing the number and activity of osteoclasts
by increasing the number and activity of osteoblasts
What is the function of Calcitriol?
decreases calcium concentration in the blood
decreases sodium concentration in the urine
increases calcium concentration in the blood
decreases sodium concentration in the blood

- Betty has a calcium poor diet and because of her age (menopause years) she is concerned about becoming hypocalcemic (low blood calcium). Once the blood levels of calcium start dropping, the body will compensate for hypocalcemia. Receptors continually feed the brain’s hypothalamus (blood-calcium regulatory center) information on calcium blood levels. The parathyroid gland will be stimulated to release parathyroid hormone (PTH). PTH will stimulate osteoclast cells to break down bone and release the stored calcium to the blood, raising the calcium blood level. a. What is the stimulus?b. What is the control center?c.
