WebAbstract. In order for our body cells to function properly, they must be surrounded in extracellular fluid that is relatively constant with regard to osmolality. The kidneys, in … Acid–base homeostasis is the homeostatic regulation of the pH of the body's extracellular fluid (ECF). The proper balance between the acids and bases (i.e. the pH) in the ECF is crucial for the normal physiology of the body—and for cellular metabolism. The pH of the intracellular fluid and the extracellular … See more In humans and many other animals, acid–base homeostasis is maintained by multiple mechanisms involved in three lines of defense: 1. Chemical: The first lines of defense are immediate, … See more Acid–base imbalance occurs when a significant insult causes the blood pH to shift out of the normal range (7.32 to 7.42 ). An abnormally low pH in the extracellular fluid is called an acidemia and an abnormally high pH is called an alkalemia. Acidemia and … See more The pH of the extracellular fluid, including the blood plasma, is normally tightly regulated between 7.32 and 7.42 by the chemical buffers, the respiratory system, and the See more • Stewart's original text at acidbase.org • On-line text at AnaesthesiaMCQ.com • Overview at kumc.edu See more

Intracellular pH is typically lower than extracellular pH due to lower concentrations of HCO 3 −. A rise of extracellular (e.g., serum) partial pressure of carbon dioxide (pCO 2) above 45 mmHg leads to formation of carbonic acid, which causes a decrease of pHi as it dissociates: H 2 O + CO 2 ⇌ H 2 CO 3 ⇌ H + + HCO 3 –.
