ABG: what determines metabolic status vs what determines respiratory status ✅HCO3
determines metabolic status and CO2 determines respiratory status
2/3 of the body's fluid resides in _____ while 1/3 of body's fluid resides in _____ ✅2/3:
intra-cellular compartment
1/3: extra-cellular compartment either interstitial or intravascular
when blood tonicity rises it triggers ____ which allows the ____ to absorb more water
✅triggers vasopressin and allows the kidneys to absorb more water which means the

this tonicity means more particles than fluid ✅hypertonic
this tonicity means more fluid than particles ✅hypotonic
