Homeostasis process by which organisms maintain a relatively stable
internal environment
Intracellular Fluid fluid inside of the cell, 2/3 of body weight
- mainly in muscle cells
fluid outside of the cell, 1/3 of bodily fluids
- blood vessels
Extracellular Fluid - skin tissues
- spinal cord
Diffusion Movement of molecules from an area of higher
concentration to an area of lower
concentration.
Osmosis movement of fluid from an area of lower solute
concentration to a higher concentration
Filtration water and solute movement occurs from an area
of high hydrostatic pressure to an area of low
hydrostatic pressure
Osmolality the number of osmotically active particles per kg of
water
Hypertonic osmolality greater than 300.

osmolality less than 300.
Hypotonic - osmotic pressure is more significant in the body
- fluids pulled from body into cell
An isotonic solution 0.09% normal saline
type of cytokine that signals cells to increase anti-viral
defenses.
Interferons (IFNs) - are released by cells that are infected with a
virus, causing other cells to become resistant
to the virus
- play a role in tumor suppression
Hypervolemia fluid volume overload
swelling of soft tissues because
of excess fluid accumulation
Edema
-Increased hydrostatic (water) pressure
- Manifestation: High BP and pitting edema
- Renal Failure, Heart Failure
- Decreased colloid osmotic pressure
Causes of edema include: - low albumin
- cirrhosis, starvation
- bacteria infections/burns
- obstruction of lymphatic system (cancer or infection)
