Term
|
Definition
proteins (- charge), such as Hgb, can bind with H+
(fast) phosphate (PO4-) can bind with H+
cellular ion exchange- can interchange H+ with K+ |

Term
| Respiratory System as Buffer |
|
Definition
| (minutes to hours) lungs regulate retention or elimination of CO2 thru changes in rate of ventilation |
|
|
Term
|
Definition
(hours to days) kidneys reabsorb more HCO3- or H+
excrete more HCO3- or H+ |
