Systemic Acid-Base and Potassium Homeostasis

Systemic Acid-Base and Potassium Homeostasis describes the set of physiological processes and regulatory systems that maintain stable blood pH and potassium concentrations within narrow limits. This is achieved through coordinated actions of the kidneys (renal potassium excretion and acid-base regulation), gut potassium sensing, cellular transport systems (notably the sodium–potassium ATPase and potassium channels), and multiple hormonal pathways (e.g., aldosterone, insulin, catecholamines). Derangements in either acid-base balance or potassium homeostasis are common and can lead to significant morbidity, particularly due to the critical roles of potassium in cardiac and neuromuscular excitability and pH in enzyme and cellular function. While many drugs and interventions influence acid-base and potassium regulation, there_is_no_single_molecular_target_for_"Systemic Acid–Base and Potassium Homeostasis" as it is an integrated system rather than a discrete molecule, receptor, enzyme, or transporter[1][2][4][5].
