Question

Quizplus · Accepted Answer

Acid-base balance is regulated by respiratory mechanisms,renal mechanisms,and buffer systems.Acid-base regulation can be monitored by examining arterial blood gases,especially blood pH.Buffer systems prevent wide swings in pH by absorbing or releasing free hydrogen ions.The lungs (respiratory mechanisms)control the carbonic acid supply via carbon dioxide.Conditions that cause retention of carbon dioxide,such as chronic obstruction pulmonary disease,lower the pH,whereas tachypneic conditions,such as hyperventilation syndrome,"blow off" carbon dioxide and increase the pH.The kidneys (renal mechanisms)regulate the concentration of plasma bicarbonate.By reabsorbing or excreting bicarbonate,the kidneys affect acid-base balance.Active transport involves the movement of fluids and electrolytes in the body.
