The phosphate and bicarbonate buffer systems are the two primary buffer systems used by the body to maintain the pH equilibrium between extracellular fluid (ECF) and intracellular fluid (ICF).
Fluids are bathed inside and outside of human cells. In actuality, the water that is present inside each cell accounts for 42% of the body's weight. Intracellular fluid is the term for the fluid found inside cells (ICF). Extracellular fluid (ECF), which refers to all fluid present outside of the cell, is distinguished from intracellular fluid by the semipermeable membrane that encloses it. This membrane permits fluid to pass through and leave while blocking the entry of undesirable chemicals or components. Water, proteins, and dissolved solutes are all present in intracellular fluid.
