Sample Question
What are the body fluid compartments, their measurements, and composition?

TBW%: M:70 F:40%, ECF: 15%, ICF: 45%, Major cations: Cl-, K+, Major anions: Na+, CO2

TBW%: M:40 F:30%, ECF: 25%, ICF: 35%, Major cations: H+, Ca2+, Major anions: Mg2+, SO4

TBW%; M:60 F:50 % ECF: 20% , 14 l = interstitial fluid + plasma -Intravascular (blood plasma, lymph) - 5% -Extravascular - Interstitial - 15% (ultrafiltrate of plasma - less proteins) Major cation: Na´+ , Anions: Cl-, HCO3- F= fluid from which cells take up O2 and nutrients and discharge metabolites into ICF: 40% - 28L (2/3) Major cations: K+, Mg+ anions: Protein, organic phosphates ECF vs. ICF Na+: EC; 142 IC: 9 K+: E; 5 , I:135 Cl-: E:103, I: 9 -Seperated by membranes -Permeable to water, but not so much to solutes Na+, Cl- , conc. of these = effective osmolarity for each compartment -ECF effective osmolarity increase, cell shrink (ICF decrease) + vv. Interstital fluid vs plasma fluid -Fluid moves across capillary membranes -Freely permeable to all plasma substances except proteins = plasma protein conc. determine effective osmolarity ECV vs. ICV -ECV; Enlarge with net gain of body fluid, (decrease with net loss) -ICV: Varies with effective osmolarity of EC-compartment, (increase osmolarity -> decrease ICV) Measurements: Dilution method -Triated water: Total body water -Mannitol: ECF -Evans blue: plasma volume Conc. in plasma measured, Volume = amount of substance present/ conc. in plasma

TBW%: M:50 F:60%, ECF: 30%, ICF: 20%, Major cations: Ca2+, Mg2+, Major anions: HCO3-, PO4
