Na+

Sodium (Na+) is a positively charged ion, meaning it has lost an electron. It plays a vital role in maintaining proper fluid balance and transmitting nerve signals in your body. Sodium ions are found mostly outside our cells, helping control blood pressure and volume, and enabling muscles and nerves to function correctly. The body carefully regulates sodium levels through the kidneys, ensuring overall health and proper cellular operation. In summary, Na+ is essential for many physiological processes, helping your body communicate and stay balanced.
