What is osmolarity?
number of solute particles (osmoles) per litre
What are the effects of a hypotonic, hypertonic and isotonic solution on a cell volume?
hypotonic: bursts
hypertonic: shrinks
isotonic: neutral
Why is a urea solution hypertonic and sucrose solution isotonic?
urea can cross cell membrane
sucrose is too large to cross membrane

intracellular volume (66%) and extracellular volume (33%)
How is an isotonic saline (0.9% NaCl) distributed?
majorly in the extracellular fluid compartment
How is a glucose 5% solution distributed?
glucose is metabolised and fluid distributed throughout both compartments
How are balanced crystalloid solutions distributed?
majorly throughout the extracellular fluid
