body fluid compartments Flashcards
define osmolarity
number of active particles in 1L of solution
what is the unit of measurement of osmolarity
mosmol/L
what is tonicity
the capability of solution to modify concentration of particles by altering water concentration
what does it mean if 2 solutions are isotonic
have equal osmotic pressure
what does it mean if a solution is hypotonic
has a lower solute concentration
what does it mean if a solution is hypertonic
has a higher solute concentration
what compartments can water be found
all compartments
what compartments can glucose be found
all
how does water move between compartments
through phospholipid bilayer, enhanced by aquaporins
how does glucose move between compartments
through membrane protein channels
what compartments are proteins found
plasma only
what are the processes in which protein leaves the plasma (2)
pinocytosis -transfer from mother to embryo
inflammation- cell membrane is damaged to allow proteins out
what compartments are electrolytes found in
intracellular fluid and interstitial fluid
how do electrolytes move through compartments
ion channels
what happens if you infuse water into a patient
freely moves into RBC causing haemolysis
