The tendency of an organism/a cell to regulate its
internal conditions, usually by a system of feedback
controls, so as to stabilize health and functioning,
regardless of the outside changing conditions
Homeostasis
The ability of the body or a cell to seek and maintain a
condition of equilibrium or stability within its internal
environment when dealing with external change
*Anticipate
The Nurse Must *Recognize
*Intervene
the potential for alterations in fluid and electrolyte
The Nurse Must: Anticipate balance associated with certain disorders and medical
treatments
The Nurse Must: the signs and symptoms of imbalance
Recognize
The Nurse Must: with appropriate action
Intervene
, Primary component of the body
Approximately 60% of the body weight of an adult
*Men 55-65%
*Women 45-55%
Varies with gender, body mass and age
*Infants 70-80%
*Older adult 45-55%
Water Content
*Infants and older adults are at greater risk of fluid
imbalances.
**Fat cells hold little water so men have more water
content and obese patients have less water content
Men have more lean muscle mass than women and
women have more fat cells and less water.
The older adult loses muscle mass decreasing body
fluid.
Body Compartments: Two 1. Intracellular
major compartments 2. Extracellular
Intracellular Fluid within the cells
Fluid outside the cells
1. Interstitial
Extracellular
2. Intravascular
3. Transcellular
Interstitial: surrounding the cells
Intravascular: within the blood vessels
very small amount of fluid found in specialized cavities
Transcellular:
(cerebrospinal fluid, synovial fluid, GI tract, etc.)

We really need it in the plasma or intravascular space!
within the cells
Intracellular Fluid (ICF):
About 28 liters
, outside the cells
Intravascular (plasma - the liquid part of blood)
About 3 liters
Extracellular Fluid (ECF):
Interstitial (around individual cells)
About 10 liters
Transcellular (very small amount)
includes cerebrospinal fluid, GI tract, pleural, etc.
Provides lubrication of musculoskeletal joints
- acts as a cushion or shock absorber
Transport mechanism throughout the body
- for nutrients, hormones, proteins
What Does the Water in Medium for cellular metabolism
Our Bodies Do? - aids in the breakdown of food
Regulation of body temperature
- HOW? - perspiration → evaporation
Acts as a component in all body cavities
- pericardial, pleural, spinal, peritoneal

Sodium - Potassium Pump: extracellular sodium and potassium levels. These levels
are essential in the action potential of cells.
* Sodium-Potassium Pump
Action potential is responsible for
The Action Potential
*Cardiac muscle contraction
*Skeletal muscle contraction
*Nerve impulse transmission
Movement occurs to adjust concentrations of solutes
and maintain homeostasis and health
This can be done by moving the solutes
Fluid and Electrolyte *Diffusion
Movement *Facilitated diffusion
*Active transport
Or by moving the water
*Osmosis
This is the movement of solutes
*Molecules move from high concentration to low
Diffusion *Passive (requires no energy)
*Occurs in liquids, solids, and gases
*The membrane separating the two areas must be
permeable to the molecules that are moving
Diffusion: Molecules move high concentration to low
