Jesus said, “If those who lead you say to you, ‘See, the kingdom is in the sky,’ then the birds of the sky will precede you. If they say to you, ‘It is in the sea,’then the fish will precede you. Rather, the kingdom is inside of you, and it is outside of you. When you come to know yourselves, then you will become known, and you will realize that it is you who are the sons of the living father. But if you will not know yourselves, you dwell in poverty and it is you who are that poverty .These words are taken from the Gospel of

Blood calcium must be tightly regulated to prevent health problems. In the case of low blood calcium, chemoreceptive cells within the parathyroid glands detect the drop in Ca2+. This signals the synthesis of the hormone parathyroid hormone (PTH). PTH enters the blood, inhibits the loss of calcium in the urine, and encourages osteoclasts and osteocytes to resorb bone and release calcium into the blood, leading to a return to homeostasis. Is this an example of negative or positive feedback? In this example, what structure is the receptor? What structure is the integrating (control) center? What structure(s) serve as effectors? List at least one example.
