A
pHCO2O2HCO3-
4
Q
acidosis
A
too much H+ (acid)ORnot enough OH- (base)
5
Q
alkalosis
A
too much OH- (base)ORnot enough H+ (acid)
6
Q
renal buffer
A
reabsorption & excretion of acids & bases
7
Q
respiratory buffer
A
hyperventilation (exhale additional CO2)hypoventilation (retain additional CO2; needs more acid)
8
Q
compensation
A
use of buffers to correct an abnormal pHrespiratory and renal compensation = when one system kicks in to balance out the other system which has become abnormal
9
