INTERACTION OF THE THYROID, PARATHYROID AND THE SKIN IN REGULATING BLOOD CALCIUM
Our body stores 99 % of calcium in the bones; only 1 percent circulates in the blood. Maintaining the right levels of blood calcium is essential as it keeps bones healthy and supports normal muscle and nerve functioning. To regulate the right blood calcium levels one has to consider; parathyroid hormone, calcitonin as well as vitamin D.
Basically, the processes occurring in the gut, bones, as well as kidneys influence blood calcium. Constantly bones undergo changes; cells called osteoclasts break them down to release calcium into the bloodstream. In the same way, bone cells called osteoblasts take up the blood calcium by using the minerals to produce new bones.
The parathyroid gland is in the form of four pea-sized nodes. Due to calcium in the blood, the parathyroid gland releases a hormone known as the parathyroid hormone (PHT). The parathyroid hormone will elevate the calcium intensity by quickening osteoclasts to modify the bone, in turn, releasing calcium into the bloodstream.
The PTH flags the kidney to reserve calcium by losing the excreted amount through urine. Similarly, PTH prompts kidney production of active vitamin D which speeds up the absorption of calcium from the gut. Either low or high levels of PTH lead to abnormally low and excessively high levels of calcium in the blood respectively (Feingold et al.,. 1987).
