MSH: The balance between acids and bases in the BODY FLUIDS. The pH (HYDROGEN-ION CONCENTRATION) of the arterial BLOOD provides an index for the total body acid-base balance.,CSP: balance between acids and bases in body fluids; balance is achieved by the offset of the ingestion and production of acidic and basic material and by the amount of acidic and basic material metabolized and excreted by the body.,NCI: In medicine, the state of having the right amount of acid and base in the blood and other body fluids. Keeping a normal acid-base equilibrium is important for the body to work the way it should.,NCI: pH homeostasis is one of numerous control systems that are involved in keeping the body's internal milieu consistent within a narrow range of variation and are important to the continuation of life. Important homeostatic mechanisms in the maintenance of blood pH include the buffering action of bicarbonate, and the actions of the renal-respiratory system. (from NCI)
