Body fluid Flashcards
How much of your total body weight is water
60%
where is water distributed in the body
66% intracellular, 33% extracellular
how much of the extracellular fluid is in plasma
20% of the ECF
how does infused (deuterated) water distribute in the body
the same as normal body water (2/3 intracellular, 1/3 extracellular)
how does infused isotonic salt water distribute
remains in the ECF (interstitial fluid, plasma)
How does an infusion of whole blood or plasma distribute in the body
in the vascular space
What’s the difference between cortical and juxtomedullar nephrons
The cortical nephrons are short with especially short thin ascending limbs- most are cortical, fewer are juxtomedullary (long loops of Henle)
Is urine concentration usually equal to less or greater than plasma
Greater- Only when a serious water load has been taken on is it anything other than greater
