Salts dissociate in aqueous solutions to release charged, inorganic atoms or molecules called ions. in biological systems, the most common of these functionally important ions are:

There are many important ions in the body, some of them are:

· Sodium ions (Na+) are the main cations found outside cells which regulate and control the level of body fluids. Too much of this ion increases water retention, leading to high blood pressure (hypertension).

· Potassium ions (K+) are the principal cations found inside the which regulate cellular functions, including nerve impulses and heartbeats, and the level of body fluids.

· Chloride ions (Cl-) are the principal anions found outside cells in the body. Like sodium and potassium ions, chloride ions are involved in maintaining acid-base and fluid balances.

· Calcium ions (Ca+) occur mainly in the skeleton and therefore it is essential for building and maintaining bones and teeth. Also, plays a crucial role in muscle contraction, and the transmission of nerve signals to cells.

The most important ions would be sodium, calcium, and potassium

Sodium and potassium are the main ions that have a big role in the action potential. Calcium also has a role in muscle contraction. If their level is altered too much, the nervous and muscle system will be greatly disrupted and the effect could be life-threatening. Phosphate and magnesium also have a role in other mechanisms but less important than those 3
