Buffering systems

Buffering systems of the human body are essential for maintaining homeostasis. Maintaining a constant pH of extracellular and intracellular fluids is also an essential part of homeostasis. The pH of extracellular fluids is physiologically in the range of 7.4 ± 0.04.

Types of buffer systems

 * 1) Bicarbonate system.
 * 2) Phosphate system.
 * 3) Hemoglobin system.
 * 4) Protein system.
