Fluid, Electrolyte, And Acid Base Balance [ COMPLETE ]

Water is the primary component of the body, accounting for roughly 60% of an adult’s weight. It is distributed between two main compartments: the intracellular fluid (inside cells) and the extracellular fluid (plasma and interstitial fluid). Fluid balance is regulated primarily by the kidneys, which adjust urine output based on hydration levels.

The human body is a masterpiece of biological engineering, maintaining a stable internal environment despite constant external changes. At the heart of this stability—known as homeostasis—is the intricate management of fluid, electrolytes, and acid-base balance. These three systems are deeply interconnected; a shift in one almost inevitably triggers a response in the others. Together, they ensure that cells are hydrated, electrical signals are transmitted, and metabolic enzymes function at their peak.

The body uses thirst mechanisms and hormones like Antidiuretic Hormone (ADH) and Aldosterone to maintain this volume. When fluid levels drop, ADH signals the kidneys to reabsorb water, while Aldosterone promotes sodium retention, which pulls water back into the bloodstream via osmosis.
