Obesity is a term that means you weigh at least 20% more than what is considered a normal weight for your height. It makes you more likely to have conditions including: Heart disease and stroke.
An Isotonic Solution creates a mild, less concentrated salt solution of 9mg of Sodium Chloride per mL of water, which has a similar salt concentration as your body and may be more comfortable to use for some people initially compated to the more concentrated Hypertonic solution.
isotonic: same osmolarity as the cells (270 - 300 mmol/l). equal solute and water--exact same number of particles in both solutions--no net movement of water. does not change cell volume. higher solute concentration surrounding cells pulls water out of the cells. hypertonic: higher osmolarity than cells (> 300 mmol/l). greater solute, less water--water moves out of cells. the cell will shrink. lower solute concentration surrounding cells causes water to move into the cells. hypotonic: lower osmolarity than cells (< 270 mmol/l). less solute, more water--water moves into cells. the cell will swell.
