Document Summary
Two types of fluid in the body: Intracellular fluid: inside of all cells: extracellular fluid: all of the fluid surrounding cells. Intracellular fluid (28 l, 67% of tbw) Extracellular fluid (14 l, 33% of tbw) o. Interstitial fluid (11 l, 26. 4% of tbw: plasma (3 l, 6. 6% of tbw) A colloidal solution, with solutes dissolves in it that will not settle out of the solution: 92% water o. 8% solutes: proteins (albumin, fibrinogen, globulins), ions, gases, waste products, etc. Plasma volume is maintained at a constant level: the amount of water input by the digestive system matches the output by the kidneys and excretory systems. Potassium concentration is higher inside of the cell. Sodium concentration is higher outside of the cell. Calcium concentration is higher outside of the cell. Chlorine concentration is higher outside of the cell: remember: peanut and chocolate covered banana (peanuts are salty: na+ and. Cl-, chocolate has ca2+, and bananas have k+)
