The parathyroid glands control calcium regulation, which is the amount of calcium that is in the blood and within the bones. An over production of the parathyroid hormone, known as hyperparathyroidism, can weaken bones, produce kidney stones, and other ailments.
hypercalcemia
hypercalcemia
In humans, calcium carbonate is only harmful if ingested in abnormally large quantities.
hypercalciuria
There are roughly 1000 grams of calcium in the human body. 99% (990 grams) of this calcium is stored in human bone (reservoir for calcium in the body). The remaining 10 grams is circulating in the blood (about 5 grams bound to protein and 5 grams circulating freely).
This can cause kidney damage due to your body not being able to handle the high levels OF calcium
out of the cell, against the concentration gradient.The calcium pump moves calcium ions out of the cell - from the cytoplasm to the extracellular fluid. Because the calcium concentration is much higher outside the cell compared to the inside, this transport is against the calcium concentration gradient. Inside calcium concentrations often increase in response to hormones and nerve input. Calcium pumps are important in terminating these responses by returning calcium concentrations to resting levels.
Hypocalcemia is the condition resulting from abnormally low levels of calcium in the blood.
Calcium carbonate is a base and hydrochloric acid is an acid but their combined pH depends on ther initial concentrations.
The Ca2+ concentration is higher in the extracellular fluid than in the cytoplasm.
Mg2+ and Ca2+
Such water is called "Hard".
The parathyroid is responsible for calcium metabolism. Without the parathyroid, there is decreased calcium circulating in the blood, which leads muscles to be hyperexcitable, which leads to spams and tremors.
