A variety of buffering systems permits blood and other bodily fluids to maintain a narrow pH range, even in the face of perturbations. A buffer is a chemical system that prevents a radical change in fluid pH by dampening the change in hydrogen ion concentrations in the case of excess acid or base.
12 Σεπ 2022 · The phosphate buffer system, while present globally, is important for the regulation of urine pH. Proteins assist with intracellular pH regulation. Red blood cells use the reaction above to help hemoglobin buffer; carbon dioxide can diffuse across red blood cells and combine with water.
Intracellular and extracellular buffers are the most immediate mechanism of defense against changes in systemic pH. Bone and proteins constitute a substantial proportion of these buffers. However, the most important buffer system is the HCO 3 − /CO 2 buffer system.
The body uses buffer systems to reduce the impact of an acute acid load. Bicarbonate is the most important buffer and functions in an open system. Fine control of acid–base status is brought about by the kidneys and liver.

Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H + ions or OH – ions, thereby maintaining an overall steady pH in the solution. pH is equal to the negative logarithm of the concentration of H + ions in solution: pH = −log [H +].
1 Σεπ 2023 · The chemical buffer system, respiratory system, and renal system are the three primary systems that manage the acid-base balance in the body. Clinical disorders impacting hydration, acid-base balance, and electrolyte status can have serious, even life-threatening repercussions; therefore, it is critical to recognise and treat them.
