is essential for bone health, blood clotting, and neurotransmission. Fluid, Electrolyte, and Acid Base Balance

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. resides mostly inside cells and is vital for

The body employs three lines of defense to maintain this balance: It is distributed between two main compartments: the

The balance of these ions is delicate. For instance, even a small deviation in potassium levels (hypokalemia or hyperkalemia) can lead to life-threatening cardiac arrhythmias. Acid-Base Balance: The Chemical Environment

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.
