PHYS 1 body fluid compartments Flashcards
what 3 main locations does water occupy in the human body?
what amount of volume makes up each compartment?
ECF can be broken down further to what?
what is the rule of thumb?
what fluid is acted on directly to control volume and composition?
this can regulate what?
extracellular fluid is intermediary between what?
fluids intake vs output
Third spacing
what is it?
often results from?
fluid compartments are separated by what?
this allows what type of movement
Composition of body fluids
ECF vs ICF
3 things that differ
what is the primary cation and anion in ECF vs ICF
electrolytes vs nonelectrolytes?
electrolytes have higher osmotic power why?
osmolality vs osmolarity
what is the approximate osmolality of all fluid compartments?
Na, Cl, Creatinine, BUN, Albumin, Osmo normal ranges real quick
ECF is in what?
ICF is in what?
ECF volume loss result in what?
ECF volume gain result in?
hematocrit is what?
normal?
ECF volume loss results in?
ECF volume gain results in?
ICF volume loss results in?
ICF volume gain results in?
How to measure volume comparing two solutions?
for ECF and ICF what do you use?
Gibbs-Donnan effect
what is it?
counteracting the gibbs-donnan effect
what force mainly causes water movement between ICF and ECF?
what is responsible for ECF and ICF movement?
what factors make free movement of fluid possible?
what would cause filtration?
absorption?
what is plasma colloid osmotic pressure?
Edema
2 things that can cause this?
4 forces that determine if fluid moves out or in?
formula?
Tonicity is what?
3 types of solutions as pertained to tonicity
what is NaCl concentration equal to in each?
what will happen to net movement in each?
Replacement therapy fluids
2 different types?
measuring plasma (serum) osmolarity
formula?
easy one?
easy one- plasma osmolarity = 2(plasma [Na])
ECF
changes in Na balance lead to?
changes in H20 balance leads to?
dehydration
occurs due to?
common reasons?
split into two types?
Hyponatremic Dehydration
sodium?
water will move where?
Na and serum osmolarity down or up?
Hypernatremic dehydration
Na?
ECF vs ICF?
what happens to serum osmolarity and Na?
Hyponatremia vs hypernatremia symptoms
fluid shift characteristics
volume contraction vs expansion
also body fluid osmolarity (whether they cause)
Darrow-yannet diagrams
X-axis?
y-axis?
solid line tells what?
dotted line tells what?
Darrow-Yannet Diagram
Iso-osmotic volume contraction
what conditions?
what will change?
Darrow-Yannet Diagram
Hyper-osmotic volume contraction
what type of fluid loss or gain?
what will change?
Darrow-Yannet Diagram
Isoosmotic volume expansion
what conditions?
what changes?
Hypo-osmotic volume expansion
what condition?
what will change?
Volume and concentration
in the calculation we added 2L of 3% NaCl
what would our Darrel-Yannet diagram do?
