✔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 - correct answer
✔triggers vasopressin and allows the kidneys to absorb more water which means the urine will be more
