Document Summary

Side note: extracellular fluid (ecf) or extracellular fluid volume (ecfv) usually denotes all body fluid outside of cells. In some animals, including mammals, the extracellular fluid can be divided into two major subcompartments, interstitial fluid and blood plasma. The extracellular fluid also includes the transcellular fluid; making up only about 2. 5 percent of the. In humans, the normal glucose concentration of extracellular fluid that is regulated by homeostasis is approximately. The ph of extracellular fluid is tightly regulated by buffers around 7. 4. The volume of ecf is typically 15l (of which 12l is interstitial fluid and 3l is plasma) Sodium (na+ = 136-145 meq/l) potassium (k+ = 3. 5-5. 5 meq/l) calcium (ca2+ = 8. 4-10. 5 meq/l) Chloride (cl- = 99-109 meq/l) hydrogen carbonate (hco3. It is poorer in proteins, as compared to intracellular fluid: plasma is extracellular matrix, water=92, proteins= 7, dissolved organic molecules, ions, trace elements and vitamins and dissolved gases=1% Na+, k+, cl-, h+, ca2+, hco3 2-
