Disturbances of acid–base homeostasis

Show Summary Details

Preview

Despite a daily load of protons, derived mainly from metabolism, the hydrogen ion concentration of arterial blood in health is tightly maintained within a slightly alkaline range (pH 7.36–7.42); concentrations of intracellular hydrogen ions are also controlled. Failure adequately to excrete or neutralize protons causes acidic conditions to prevail (decreased pH): undue intake of base, uncompensated loss of protons—or the substrates from which they are derived—induces an alkaline milieu (raised pH)....
