- Isotonic solution
- -Same concentration as intracellular fluid -Moves fluid in/out of cell at same rate -Normal saline .9% and Dextrose 5% are ex: manufactured Isotonic Solutions
- Fluid Balance
- Regulation of amt & composition of body's fluids -2 divisions of body fluid 1. Extracellular 2. Intracellular -Concentration of fluids affects fluid movement and balance
- Homeostasis
- Body's ability to regulate and maintain inner balance to sustain life - Measured by BP, HR, Resp. Rate, temp and other indicators.
- Extracellular
- Fluid outside the cell
- Intracellular
- Fluid Inside the cell
- Hypertonic solution
- More concentrated than intracellular fluid Draws fluid away from the cell and causes the cell to shrink
- Hypotonic Solution
- Less concentrated then intracellular fluid Results in excess fluid entering the cell, and may cause it to rupture
