I thought,among 600ml,

2/3rd =ICF and 1/3rd= ECF,so

1/3rd of 600ml = 200ml = ECF,

since 1/3rd of ECF is plasma vol,

1/3rd of 200ml= 66.66=approx 50ml is Plasma Vol..

what is the correct answer mash???

If u consider in 4parts..
ICF= 3/4 of TBW
ECF = 1/4 of TBW
ISF = 3/4TH OF ECF
VF = 1/4TH OF ECF.

If u consider in 3 parts..
ICF = 2/3 of TBW
ECF = 1/3 of TBW
ISF = 2/3rd OF ECF
VF = 1/3rd OF ECF..

Yep, but it redistributes according to osmotic gradients.
