1. Sodium The most abundant electrolyte in the body and primary electrolyte in extra-
cellular fluid
2. Potassium Found in intracellular fluid, major intracellular cation. Plays important role
in maintaing fluid osmo and volume within the cell. Essential for normal
membrane excitability & nerve impulses. Needed for protein synthesis &
break down of glycogen & maintain plasma acid balance.
3. Calcium Ca+ / phos to form the mineral salts of bones and teeth. 99% concentrated
in bones and teeth. Ca+ promotes normal transmission of nerve impulses &
helps regulate norms, muscle contraction & relaxation.
4. Magnesium (Mg+) Second most abundant cation in the intracellular fluid; involved in the me-
tabolism of carbs & proteins, also important in functioning of heart, nerves &
muscles.
5. Osmolality Concentration of a solution determined by the number of dissolved particles
per kilogram of wTer; controls
6. Which hormones Renin & ADH
have a major effect
on fluid volume &
balance?
7. Increased plasma The sensation of thirst.
Osmo stimulates the
osmoreceptors in
the hypothalamus to
trigger this regulato-
ry ,echanism
8. A good indicator of Body weight.
