Fluids and Electrolyes: Water
DrBruce Forciea・2 minutes read
The human body is about 60% water, distributed between intracellular and extracellular compartments, with water balance critical for overall health through regulation by mechanisms like antidiuretic hormone secretion and thirst control by the hypothalamus. Imbalances in water levels, such as dehydration or water intoxication, can have severe consequences on cell function and lead to conditions like shock or edema in vital organs.
Insights
- The human body is composed of approximately 60% water, primarily distributed between intracellular and extracellular compartments. Maintaining water balance is essential, with intake from metabolic processes and fluids needing to match losses through various bodily functions.
- Water balance is intricately regulated by mechanisms like antidiuretic hormone secretion and thirst control, ensuring proper hydration levels. Imbalances, whether from dehydration or water overload, can have serious repercussions on cellular functions, potentially causing shock or edema in critical organs like the brain and lungs.
