WebThe body has three lines of defense against departures from normal plasma pH: the chemical buffers, the respiratory system, and the renal system. The chemical buffers … WebThe body's acid– base balance is tightly regulated to keep the arterial blood pH between 7.38 and 7.42. Buffer solutions keep the pH constant in a wide variety of chemical actions. A buffer solution is a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid. The bicarbonate buffering system maintains optimal pH ...

WebA decrease in pH is sensed by arterial chemoreceptors and leads to increases in tidal volume or respiratory rate; CO 2 is exhaled and blood pH increases. In contrast to chemical buffering, which is immediate, pulmonary regulation occurs over minutes to hours. It is about 50 to 75% effective and does not completely normalize pH.
