NUR 339 Fluids
- intracellular fluid
Answer majority of the fluids in the body
- diffusion
Answer movement of particles high to low
- osmosis
Answer water high concentration to low
- passive transport
Answer does not require energy for movement to occur high to low
- active transport
Answer requires energy for movement to occur low to high
- Osmolarity
Answer number of milliosmoles of solute per 1 kg of water
- tonicity
Answer ability of solutes to cause an osmotic gradient that promotes water movement
-refers to sodium chloride concentration
-determines by how it compares to normal blood concentration three types 1 / 2
Answer isotonic, hypertonic, hypotonic
- isotonic solutions
Answer equal to blood concentration
-solute and water balanced no net movement of fluid between ECF and ICF remains balanced, no change in cells
- hypertonic solutions
Answer concentrated blood concentration
-ECF more concentrated -concentrated vascular space pulls fluid cells to blood -net movement of fluid from ICF to ECF -cell size shrinks due to fluid loss
- hypotonic solutions
Answer dilute blood concentration
-ECF less concentrated -more water than solute -pressure gradient goes from ECF to ICF -cell size increases due to fluid increase
- capillary hydrostatic pressure
Answer pressure exerted by the fluids against the blood vessel walls
-reflects BP -pressure is higher at arterial end, lower at venous
- filtration
