Application Question 1- Homeostasis osteoporosis

    Our body maintains calcium by homeostasis. When we don’t consume enough calcium through our diet, the body compensates by adjusting calcium levels.A special gland parathyroid gland is the control center that  senses changes in blood calcium levels and responds accordingly. Low calcium (stimulus) triggers the (effector) parathyroid hormone release.Parathyroid hormone stimulates bone cells  to break down bone tissue this process is called resorption. As a result, calcium is released from the bones into the bloodstream.When blood calcium returns to normal, PTH secretion stopped.This is the example of Negative Feedback Loop.The system self-regulates to prevent extreme deviations from the set point.Ultimately, this helps prevent conditions of osteoporosis.
