1. What parts make up extra cellular fluid?: Answer Intravascular fluid (IVF) or blood, Interstitial fluid (ISF) or intercellular fluid, Cerebrospinal fluid (CSF), Transcellular fluids present in various secretions, such as those in the pericardial (heart) cavity orthe synovial cavities of the joints 2. Filtration: Answer movement of water and solutesfrom blood ( high pressure) to ISF (lowpressure) area 3. Diffusion: Answer Movement of molecules from an area of higher concentration to anarea of lower concentration. 4. Osmosis: Answer diffusion of water across a selectively permeable membrane. Lowsolute concentration (ISF) to high concentration (blood) 5. Active transport: Answer the movement of ions or molecules across a cell membraneinto a region of higher concentration, assisted by enzymes and requiring energy. 6. Hydrostatic pressure: Answer fluid moves out from (or is "pushed" out of) the capillaryinto the interstitial compartment.
