Extracellular calcium

Extracellular calcium refers to the calcium ions that exist outside of cells in the body. This calcium plays a crucial role in various physiological processes, including muscle contraction, blood clotting, and nerve signaling. Maintaining the right level of extracellular calcium is essential for overall health, as it helps regulate heart rhythms and is vital for bone strength. The body carefully controls calcium levels through hormones and dietary intake to ensure these processes function properly and efficiently.
