WitrynaIn cellular physiology, buffers are an important way for the cell to maintain constant or smoothly changing conditions. Since cellular metabolism is constantly producing and … WitrynaThe weakness of buffers is they only resist changes, they do not prevent changes. Therefore, in a buffered system if you add an acid or a base you will see a small change in pH, but not nearly as large a change as would be observed in the absence of a buffer. The most important buffer in the blood is the bicarbonate buffer system, see below.

Witrynabuffer system outlined above. The importance of this buffer pair relates to certain key properties: bicarbon-ate is present in a relatively high concentration in the ECF (24mmol/L) and the components of the buffer system are effectively under physiological control: the CO 2 by the lungs, and the bicarbonate by the kidneys.

WitrynaThe function of a buffer is to keep the pH of a solution within a narrow range.
