Bicarbonate buffering system — The Bicarbonate buffering system is the most important buffer solution for maintaining a relatively constant pH in the plasma.It functions via blood buffering with bicarbonate. The enzyme carbonic anhydrase maintains the equilibrium between… … Wikipedia
buffer — 1. A mixture of an acid and its conjugate base (salt), such as H2CO3/HCO3−; H2PO4−/HPO42−, that, when present in a solution, reduces any changes in pH that would otherwise occur in the solution when acid or alkali is added to it; … Medical dictionary
buffer base — the sum of all the buffer anions in the blood (bicarbonate, hemoglobin, proteins, and phosphate), determined by titrating the blood with a strong acid; it is used as an index of the degree of metabolic disturbance in the acid base balance … Medical dictionary
buffer salt — a salt, such as sodium bicarbonate or sodium phosphate, the anion of which functions as a conjugate base in a buffer system … Medical dictionary
buffer therapy — intravenous injection of buffer substances, such as sodium bicarbonate, with the object of lowering the hydrogen ion concentration … Medical dictionary
buffer — n. a solution whose hydrogen ion concentration (pH) remains virtually unchanged by dilution or by the addition of acid or alkali. The chief buffer of the blood and extracellular body fluids is the bicarbonate (H2CO3/HCO3 ) system. See also: acid… … The new mediacal dictionary
