Document Summary
Draw diagram of two cells and capillary: icf compartment, ecf compartment, interstitial fluid compartment, plasma, cell membrane. Know relative size of each (% body water) [know majority of water is in the. Know the chemical composition of: icf, interstitial fluid, plasma; sodium, potassium, chloride, and proteins. What accounts for the differences in chemical composition of icf, interstitial fluids and plasma. The volume of fluid and concentration of ions must be controlled through homeostasis in order for our organ systems to function properly. 26. 4% pf tbw: plasma; water portion of blood 6. 6% of tbw. 92% water; 8% proteins, ions, nutrients, gases, waste products. Colloidal solution (suspended substances do not settle out of solution. Most suspended substances are plasma proteins (albumins, globulins, fibrinogen) Higher concentrations of na+, ca2+, and cl- ions in the ecf. Higher concentrations of k+ ions and proteins in the icf due to the selectively permeability of the plasma membrane. The cell (plasma) membrane forms selectively permeable barrier between.
