Document Summary
Homeostasis controls the volume of fluid and the ion concentration so organs function properly. Homeostasis: maintenance of relatively stable conditions in our internal environment. Body is divided into 2 major fluid compartments: intracellular fluid (inside cells, extracellular fluid (everything outside cells) Extracellular fluid makes up the internal environment of our body: divided into: Total body water (42l): intracellular fluid: 67, interstitial compartment (extracellular): 26. 4, plasma (extracellular): 6. 6% Pale yellow fluid consisting of 92% water, 8% other substances (proteins, ions, nutrents, gases, waste) Collodial solution liquid containing suspended substances that do not settle out of solution: suspended substances are plasma proteins albumins, globulins, fibrinogen. Water intake through the digestive tract closely matches water loss through the kidneys, lungs, digestive tract. 2. 5 chemical composition of the body fluids. There are different ions in our body and they all have different concentrations and their relative distribution is different.
