Calcium homeostasis ie maintaining a blood calcium level of about 10 mgdL is critical for normal body functions. In general negative feedback loops allow systems to self-stabilize. Blood calcium homeostasis feedback loop.
Blood Calcium Homeostasis Feedback Loop, The effects of PTH are to raise blood levels of calcium. Senorscontrol center Hormone effectors. The positive feedback loop maintains the direction of stimulus and possibly accelerates it. Negative feedback occurs when a systems output acts to reduce or dampen the processes that lead to the output of that system resulting in less output.

Low blood calcium levels initiate the production and secretion of PTH. Calcium homeostasis also called calcium metabolism is the process by which our bodies maintain calcium levels within this optimal range. Homeostasis is performed so the body can maintain its internal set point. When the amount of calcium in blood rises above the normal range parafollicular cells in the thyroid gland secrete calcitonin.
In this feedback system blood calcium level is the variable because it changes in response to the environment.
