b. Adult females
i. < 65 y/o = 50%
> 65 y/o = 45%
1. 1/3 TWB Extracellular fluid volume
2. Controlled by Na
retention and excretion
3. Water passively follows
sodium
4. Body ignores ECF as a
whole

Volume
i. Volume in the arteries
ii. ~ 700ml

changes in the EABV
-Decreased EABV- increase
release of catecholamines
and increases CO and SVR,
activates RAAS, increased
antidiuretic hormone
secretion
-Increase EABV-
suppresses RAAS, increase
release of atrial natriuretic
peptide

refill

(SBP decrease > 20mmHg
with standing)

wgt.
7. Depressed mental status
of loss of consciousness
