Textbook Question
Chapter 1, Problem 19CT
Parathyroid hormone (PTH) is secreted in response to a drop in the calcium level in the blood. The secretion of PTH is regulated by a negative feedback mechanism. What can you expect to happen to the calcium blood level as increased amounts of PTH are secreted, and why?

A hormone called calcitonin, produced by the thyroid gland, is released in response to increased levels of calcium ions in the blood. If this hormone acts through negative feedback, what effect will its release have on blood calcium levels?
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.
Osteoporosis is a loss of bone density that can be caused by low concentrations of calcium in bones. Abnormal bone calcium is MOST likely caused by dysregulation of which organ?
A.
adrenal gland
B.
pancreas
C.
parathyroid gland
D.
thymus
