Document Summary

Introduction: volume of fluid and concentration of ions is closely controlled so our organ systems can function properly. Icf contains 28l, interstitial compartment contains 11l, and the plasma contains 3l. A quick looks at plasma: plasma: pale yellow fluid that consists of 92% water and 8% other (proteins, ions, nutrients, gases, and waste) It is a colloidal solution (liquid containing suspended substances that do of solution). Most suspended substances are plasma proteins, which albumins, globulins and fibrinogen: plasma volume = constant. Normally, water intake through the digestive matches water loss through the kidneys, lungs, digestive tract, and skin substances not settle out include tract closely. Chemical composition of body fluids: sodium (na+): Interstitial fluid: 150 mosm/l h2o: plasma: 148 mosm/l h2o, potassium (k+): Interstitial fluid: 5 mosm/l h2o: plasma: 4. 8 mosm/l h2o, calcium (ca+): Interstitial fluid: 2. 4 mosm/l h2o: plasma: 2. 5 mosm/l h2o, chloride (cl-): Interstitial fluid: 125 mosm/l h2o: plasma: 102 mosm/l h2o, proteins (pr):
