| Question | Answer |
|---|---|
| Hooke's Law | An elastic body will stretch equally for every force applied, but beyond the elastic limit there will be permanent distortion |
| Apply Hooke's Law to a spring-weight system | shows how a spring will hold its elasticity when weight is applied to the bottom and if too much weight is applied the recoil of the spring will be lost |
| Define Lung Compliance | The ease at which the lungs distend |
| Calculate Lung Compliance | change in volume/change in pressure 800mL/20cmH2O 40cmH2O/mL |
| Define Surface Tension | The tension found at the surface of a liquid created by the cohesive forces inside the liquid |
| The 4 Pressures | Capillary osmotic pressure Capillary hydrostatic pressure Interstitial osmotic pressure Interstitial hydrostatic pressure |
| Explain the role of the lymph system as it pertains to fluid exchange at the capillary level | The lymphatic system drains fluid and prevents fluid accumulation in the pulmonary interstitial |
| Define Osmosis | The movement of a solvent through a semi permeable membrane from a solution of lower concentration to a higher concentration |
| Define Diffusion | The passive movement of molecules from an area of higher concentration to lower concentration |
| Define Hydrostatic Pressure | The pressure created within a column of liquid and is dependent on the height and density of the liquid |
| Describe LaPlace's Law | The pressure is inversely related to the radius and directly related to the surface tension at the air liquid interface |
