PAT 201 Fluids Exam Questions With Correct
Answers
Intracellular - CORRECT ANSWER✔✔-ICF; 2/3 of total body fluid inside of cells
| | | | | | | | | | |
Extracellular - CORRECT ANSWER✔✔-ECF; 1/3 of total body fluid outside of cells
| | | | | | | | | | |
What is ECF composed of? - CORRECT ANSWER✔✔-plasma and interstitial fluid
| | | | | | | | | | |
(fluid between cells)
| |
What are examples of ECF? - CORRECT ANSWER✔✔-- Intravascular fluid (inside
| | | | | | | | | | |
vessels)
- cerebrospinal fluid
| | |
- sweat
|
- urine
|
Where does fluid move? - CORRECT ANSWER✔✔-Fluid moves between ICF and
| | | | | | | | | | |
ECF compartments through semi permeable membranes
| | | | |
Diffusion - CORRECT ANSWER✔✔-movement of water
| | | | |
Difference between simple and facilitated diffusion - CORRECT ANSWER✔✔-
| | | | | | | |
simple: Low to high solute [c] (gravity)
| | | | | |
, facilitated: molecules help more particles (no ATP)
| | | | | |
active transport - CORRECT ANSWER✔✔-against the concentration gradient. Low
| | | | | | | | |
to high. YES ATP
| | |
- movement is going against the gradient
| | | | | |
- E.X sodium potassium ATPase pump
| | | | |
*Osmosis* |
and why water moves between ICF and ECF - CORRECT ANSWER✔✔-water from
| | | | | | | | | | | |
low to high solute [C]
| | | |
- water crosses the cell membrane freely so the osmolality of TBW (total body
| | | | | | | | | | | | | |
water) is normally at equilibrium
| | | | |
WATER WANTS TO BE EQUAL ON EITHER SIDE OF THE SEMI-PERMEABLE
| | | | | | | | | | |
MEMBRANE
- when ECF osmolality changes, water moves from one compartment to another
| | | | | | | | | | | |
until osmotic equilibrium is established.
| | | |
Filtration - CORRECT ANSWER✔✔-A process that separates materials based on
| | | | | | | | | |
the size of their particles.
| | | |
True or False: simple and facilitated diffusion are both passive - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-TRUE- they do not require ATP (O2 and CO2) | | | | | | | |
Forces Favouring Filtration - CORRECT ANSWER✔✔-- Capillary hydrostatic
| | | | | | | |
pressure (blood pressure) | | |
- Interstitial oncotic pressure (water-pulling)
| | | |
