Document Summary

Module 2- body fluids: thanks to homeostasis, the volume of fluids and concentration of ions is closely controlled so that our organ systems can function properly. Body fluid compartments: the body is divided into two major fluid compartments: Intracellular fluid- the fluid inside all the cells. a: extracellular fluid- the fluid outside cells. Keep in mind that the extracellular fluid makes up the makes up the internal environment of the body. Tbw: the plasma contains 3l (0. 8 gallons) or 6. 6% tbw. A closer look at plasma: plasma is a pale yellow fluid consisting of about 92% water and. *** note there is a big difference between ion concentrations inside and outside the cell. However, there is a small difference between the plasma and interstitial fluids. It"s because of the cell membrane, which forms a physical barrier between the intracellular and extracellular fluid. It can do this because it is selectively permeable. A summary of the relative distributions of ions.
