QUESTIONS WITH VERIFIED
ANSWERS.
Normal Sodium Levels - ANSWER-135 - 145 mEg/L
Function of Sodium - ANSWER-Regulate Fluid Volume
Help maintain blood volume
Interact with calcium to maintain contraction
Stimulate nerve impulses
Regulation of Sodium? - ANSWER-Moves by active transport
cell membrane
Regulated by aldosterone and ADH levels
Reabsorbed and excreted though kidneys
Low Sodium may be caused by excess water intake
Sodium falls Water!
