Resumen:

In this chapter, systemic acid-base physiological mechanisms are discussed. Understanding of these mechanisms is necessary to comprehend basic systemic hydrogen and bicarbonate ions transportation through the body fluids, as well as the lungs and kidneys. These organs comprised the pulmonary and metabolic components of acid-base physiology. Carbon dioxide (CO2), produced by the body cells, is transported and expelled into the lungs, in exchange by O2. CO2 is dissolved in water, where it binds to a hydrogen ion (H+) molecule to form carbon dioxide (H2CO3), and then bicarbonate (H2CO3-). Serum bicarbonate is the most important buffer of the extracellular fluid (ECF). Hydrogen ions are excreted by the kidneys. Acid-base defense mechanisms, namely metabolic acidosis and alkalosis and, respiratory acidosis and alkalosis are reviewed. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
