- What is diffusion?
Answer -random movement of particles from higher concentration to area of lower concentration
-if one side of the membrane has a higher solute concentration than the other side. The body again seeks to restore balance through redistribution of electrolytes -electrolytes will move from hypertonic to hypotonic side until isotonic relationship is established -movement direction in diffusion is opposite that in osmosis
- What is osmosis?
Answer movement of water from area of more water (fewer solutes to less water (more solutes)
- What is osmolality?
Answer osmolar concentration in 1 kg of water
- What is osmolality determined by?
Answer sodium level
- What is tonicity?
