(82 cards)
Fluid and electrolyte balance is a ________ process that is crucial for
dynamic, life and homeostasis.
normal pH range
7.35 to 7.45
60% of weight - typical adult consists of
fluid
fluid is made up of
water and electrolytes
Factors that influence the amount of body fluid are
age, gender, and body fat.
younger people have a higher percentage of
body fluid than older people,
men have proportionately more _____ than women
body fluid
obese have less fluid than those who are thin because
fat cells contain little water
Body fluid is located in
two fluid compartments: ICS & ECS
intracellular space (ICS)
fluid inside the cells)
extracellular space (ECS)
fluid outside the cells).
Approximately two thirds of body fluid is intracellular fluid (ICF) and is located primarily in
the skeletal muscle mass;
ECF compartment is further divided into (3)
intravascular, interstitial, transcellular fluid spaces
one third of ______ is in the extracellular fluid (ECF).
Body fluid
intravascular space (IVS)
fluid within the blood vessels
AKA PLASMA
Plasma is made up of
water, along with molecules, electrolytes, and proteins, minus blood cells and platelets.
