Normal Physiology
- upkeep of homeostasis
- conposition of fluids and electrolyte are saved within slim limits
- water content material varies with age, gender, and fat content material
Fluid Compartments in the frame
•Intracellular fluid (ICF)
•Extracellular fluid (ECF)
•Interstitial
•Intravascular (plasma)
•Transcellular
Calculation of fluid gain or loss
One liter of water weighs 2.2 lb (1 kg)
Cations
Positively charged ion
Anions
Negatively charged ions
ICF - electrolyte composition
Prevalent cation: K+
Prevalent anion: PO43-
ECF - electrolyte composition
