Ca2+

Calcium ions (Ca²⁺) are charged particles essential for many biological processes. They play a key role in muscle contraction, helping muscles tighten and relax. Calcium also aids in transmitting signals between nerve cells, influencing how we perceive stimuli and control movements. Additionally, Ca²⁺ is vital for building strong bones and teeth, and it helps regulate blood flow and blood pressure. The body maintains balanced calcium levels in the blood through bones, kidneys, and intestines. Proper calcium function is crucial for overall health, and disruptions can lead to health issues like weak bones or nerve problems.
