Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
RespiratoryOrgans of the respiratory system: nose, pharynx, larynx, trachea, bronchi, alveoli
Parathyroid glands
Parathyroid hormone (PTH) and calcitonin regulate blood calcium levels. PTH increases the calcium concentration in the blood, and calcitonin decreases it.
Calcitonin
parathyroid hormone/calcitonin
thyroid gland

Calcitonin and PTH
The parathyroid glands produce and secrete parathyroid hormone which regulates calcium levels in the blood. Since it increases blood calcium levels, it promotes the function of osteoclasts, which reduce the calcium in bones and promote its increase in the blood stream.
The exchange that takes place between organs and blood are **** and ********
Parathyroid glands secrete PTH (parathyroid hormone) to regulate blood calcium levels.
Capillaries make possible the exchange of molecules between blood and interstitial fluid. Sphincters open and close to regulate the flow of blood through capillary beds.
