The Role of Calcium in the Human Body
When calcium levels in the body fall too low, the bones have to supply calcium to tissues and fluids so that normal biological functions can continue. As a result, calcium deficiency can cause the bones to weaken, raising the risk of fracture and increasing the risk of osteoporosis.
What is Calcium Carbonate? - Industrial Minerals …
The calcium carbonate water runs down and eventually reaches an air-filled cavity underground where the carbon dioxide can be released. When it is released, the calcium carbonate crystallizes again. Stalactite and stalagmite formations are created when water containing calcium carbonate drips, leaving some mineral at the source of the drip at the roof of the cave and some where it falls.
