balance is what type
of process?
What is homeostasis? constant internal equilibrium
Is a patient in acute No! They wouldn't need t be in the hospital if
care in homeostasis? they were.
How can you by performing an assessment
determine if a person
is in homeostasis?

is ICF? ECF? ECF: 1/3rd
active chemicals that carry positive (cations)
What are electrolytes?
and negative (anions) electrical charges
,What are the major sodium, potassium, calcium, magnesium
cations?
What are the major chloride, bicarbonate, phosphate, sulfate
anions?
Movement of fluid -hydrostatic pressure and osmotic pressure
through capillary walls
depends on...
What is hydrostatic pressure exerted on the walls of the blood
pressure? vessels
What is osmotic pressure exerted by protein in plasma
pressure?
The direction of fluid differences in hydrostatic and osmotic
movement depends pressure
on what?
regulation of fluid from area
of low solute concentration
What is osmosis?
to area of high solute
concentration
solutes move from area of
higher concentration to one
What is diffusion?
of lower concentration
The movement of water and solutes across the
What is filtration? cell membrane due to hydrostatic pressure
from the cardiovascular system.
physiologic pump that moves fluid from areas
What is active
of lower concentration of one of higher
transport?
concentration
,The body maintains a the sodium-potassium pump
higher concentration

sodium and
intracellular potassium
due to what?
What does active ATP energy
transport require?
the concentration of fluid that affects the
What is osmolality? movement of water between fluid
compartments by osmosis
