BIG QUESTINO NIGHT B4 DAT....
in the kidney do u look at the countercurrent model or the two-solute model when tehy ask question bout it
say if they ask where does Na go in and where does it go out
well in the counter current Na goes in in descending and out in ascending
but in in twosolute Na is isotonic in the descending but diffuses out in ascending so whhich would u pick
ALSO
b cells originate and mature in spleen
t cells orginate in bone marrow mature in thymus
in fetus rbc the spleen and liver makes the rbc what about wbc?
also what do the mean by permeability does that mean Na or water or w/e it is is going in AND out?
