| Frage | Antworten |
| What is the difference between osmolarity and osmolality | Osmolarity: miliosmoles/L Osmolality: miliosmoles/kg |
| What does osmolarity control in the 1. Plasma 2. Intracellular fluid | The volume of the plasma and cell |
| What is the relationship between osmolarity and Avogadro's number? | 1 osm=Avogadro's number |
| What is the main ion in plasma? It has more.... and contains ... .... and ... as negative charges | Na+ Ca2+ Cl-, HCO3-, proteins |
| What is the main intracellular ion? It has ... ... and ... as negative charges | K+ Cl-, amino acids, proteins |
| Water makes up ...% of total body composition Of that, ...% is intracellular and ...% is extracellular | 1. 60% 2. 40% intracellular 3. 20% extracelluar - 15% interstitial between cells - 5% in plasma |
| What are some minor fluid compartments? | 1. Cerebral spinal fluid 2. Synovial fluid 3. Lymph |
| Body fluids are made up of? | 1. Ions (eg. Na+, Cl-, K+) 2. Proteins 3. Dissolved gases/nutrients/metabolites 4. Cells in blood |
| What is the dilution method and how does it determine volume? | Concentration=substance/volume So Volume=substance/concentration You can add known substance to unknown volume, measure concentration |
| For the dilution method, the substance used must be... | 1. Non toxic 2. Slowly metabolised 3. Can't cross capillary in plasma 4. Can't enter cells 5. Distribute to all H20 |
| Hypotonic is when the cell has ... ions and leads to ..... Hypertonic is when the cell has ...ions and leads to .... Isotonic= | 1. MORE, swelling 2. LESS, shrinking 3. Equal amount of ions |
| Crystalloid pressure is due to ... and must be .... between intra/extracellular | ions equal |
| Oncotic pressure is due to... It plays a role in fluid transport because | 1. Proteins 2. Hydrostatic pressure initially draws fluid OUT of capillary. Oncotic pressure in venous end draws fluid back in |
| What are the three plasma proteins? | 1. Albumin-transport 2. Globulins-transport+immunity 3. Fibrinogen-blood clotting |
| What are normal RBC/WBC counts? | RBC: 4.2-6.1 million/microliter WBC: 4500-11,000/microliter |
| What is the normal range of plasma osmolarity? | 275-300 milliosmoles (mOsm)/L |
