Reаd the fоllоwing scenаriо аnd answer the questions listed. A woman who is lactose-intolerant avoids milk/dairy but doesn't follow her doctor's recommendation to take calcium supplements. Over time, her blood calcium levels drop. Cells of the parathyroid gland detect the decrease in blood calcium levels. The parathyroid gland secretes parathyroid hormone into the bloodstream. Parathyroid hormone causes bone cells to break down bone tissue. As this breakdown occurs, calcium which was stored in the bones is released into the bloodstream. As a result, her blood calcium levels increase. What type of feedback loop is this? What is the stimulus? What is the receptor? What is the effector and response?
