Question | Answer |
---|---|
State of equilibrium or balance | homeostasis |
primary body fluid, most important nutrient in the body. | water |
Fluid found within the boundaries of cell membranes.Considered 1st space. 40% of body weight. | intracellular |
All of the fluid not contained within a cell. | extracellular |
Space inbetween cells | interstitial |
the loosening of chemical bonds causing the elements tot ake on an electrical charge | ionization |
positive ions | cation |
negative ions | anion |
movement of water through a semi-permeable membrane of an area of lower concentration of particles to an area of higher concentration of particles | osmosis |
what is the normal amt of blood plasma | 275-295 |
Fluids that have an osmolarity that is equal to blood are | isotonic |
Fluids that have an osmolarity that is significantly less that blood are | hypotonic |
fluids that have an osmolarity that is significantly higher than blood are | hypertonic |
Random movement of particles from an area of highter concentration of particles to an area of lower concentration of particles | diffusion |
Primary E-lyte in extracellular fluid. Controls body fluid distribution and assists with nerve impulse transmission. | Sodium |
Normal sodium level | 135-145 |
Primary cation in intracellular fluid. Vital roll in transmission of electrical impulses (think heart). No method exists to "conserve". | potassium |
Normal potassium level. | 3.5-5 |
