Detailed explanation-1: -pH is maintained in the body using primarily three mechanisms: buffer systems, respiratory control, and renal control.
Detailed explanation-2: -Blood pH is regulated by multiple homeostatic mechanisms, including chemical buffers, respiration, and the kidneys. The bicarbonate buffer system can act within seconds to minutes to counteract changes in pH, while the lungs take minutes, and the kidneys take hours to days.
Detailed explanation-3: -Increases in blood pH indicate alkalemia. Increases can be a result of a respiratory (or metabolic) disturbance. Respiratory alkalosis is the result of alveolar hyperventilation. Hyperventilation (ie, decreased Pco2) causes removal of CO2 and subsequent H+ faster than H+ is being produced.
