Importance of physiological buffers
WitrynaA buffer in the physiological sense usually refers to the ways the body manages to keep the pH of the blood in narrow tolerance limits. To buffer something means to lessen the impact of an injury/insult/stress to the system. “Soften the blow,” so to speak. 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.
