- extracellular fluid 1/3
- -> intravascular 1/4
- -> interstitial 3/4
what do we use to measure extracellular fluid volume?
what do we use to measure the plasma volume?
how do we calculate plasma osmolarity?
- 2[Na+] + [K+] + [urea] + [glucose]

- -> efficiency = correction/ error (must be negative number)
give FOUR examples of POSITIVE feedback system.
- blood clot formation
- preovulatory LH surge by oestrogen
