Blood calcium levels are regulated homeostatically Kelly recently decided she wanted to go vegan and cut all meat dairy and animal by products from her diet Unfortunately Kelly did not do this in a healthy way and began to eat mostly bread and very few vegetables Kelly did not get enough calcium in her diet causing her blood calcium levels to decline This decrease in calcium was detected by receptors in Kelly s parathyroid gland In response the parathyroid gland secreted the hormone PTH This hormone acts on the bone cells causing them to break down osseous tissue and in the process release stored calcium into the blood This break down of bone returned Kelly s blood calcium levels to normal allowing her cells to function appropriately In this example of homeostasis one effector would be O Kelly s poor diet O calcium in the bones O the brain OPTH activating the bone cells osteoclasts O calcium in the blood
