The pH (or the amount of hydrogen ions (H+) in a solution) level of the blood is important in ensuring the proper functionality of biological systems. The optimal pH level of the blood is 7.4, which is maintained by three different types of buffer systems working in the body. The addition of an acid or a base to a substance changes its pH level. A buffer is a solution (or a substance) that has the ability to maintain pH and bring it back to its optimal value.
