Document Summary

Introduction: the internal environment is bathed in fluids, the volume of fluid and concentration of ions is closely controlled, homeostasis: the maintenance of relatively stable conditions in our internal environment. Body fluid compartments: two major fluid compartments: Intracellular fluid compartment (icf - inside all the cells: extracellular fluid compartment (ecf - everything outside the cells, makes up the internal environment of the body. Interstitial fluid compartment (the fluid directly outside, bathing the cells: plasma (watery portion of the blood, avg. 70kg person: total body water (tbw) = 42 l. Icf = 28 l: ecf =14 l. Interstitial = 11 l: plasma = 3 l. Chemical composition of the body fluids: relative distribution of ions, sizeable difference between inside and outside, small difference between plasma and interstitial fluid. Interstitial: large: potassium ions (k+, plasma: small. Interstitial: small: calcium ions (ca++, plasma: small. Interstitial: small: chloride ions (cl-, plasma: large. Interstitial: large: protein ions (pr, plasma: smaller.
