Study Notes
Body Fluid Homeostasis
- Body maintains homeostasis by balancing fluid characteristics: volume, concentration (osmolality), composition (electrolyte concentration), and acidity (pH).
- Healthy adults have 55% to 60% body fluid; older adults have 50% to 55%.
- Fluid movement between compartments (ICF, ECF) happens via selective membranes and methods like diffusion, active transport, filtration, and osmosis.
- Homeostasis is maintained through input and output.
- Fluid intake is affected by thirst, social factors, and habits.
- Fluid output occurs in kidneys, skin, lungs, and GI tract, with kidneys being the primary regulators.
Fluid Imbalances
- Volume imbalances arise from too little or too much isotonic fluid.
- Osmolality imbalances involve hypertonic or hypotonic body fluids.
- Hypernatremia (water deficit) and hyponatremia (water excess) are examples of osmolality imbalances.
Body Fluid Compartments
- Body fluids are divided into intracellular (ICF) and extracellular (ECF) compartments.
- ICF holds two-thirds of body water, within cells.
- ECF holds one-third of body water, outside cells.
- ECF further divides into:
- Intravascular fluid (plasma).
- Interstitial fluid (between cells and blood vessels).
- Transcellular fluids (secreted by epithelial cells: cerebrospinal, pleural, peritoneal, synovial fluids).

Description
This quiz covers the essential concepts of body fluid homeostasis, including fluid movement between compartments and the mechanisms that regulate fluid volume and composition. It also explores fluid imbalances such as hypernatremia and hyponatremia, essential for understanding human physiology and health. Test your knowledge on how the body maintains fluid balance and responds to changes.
