A principle for calculating cardiac output from oxygen uptake or carbon dioxide elimination | Ficks law of diffusion |
The law that states gas pressure is inversely proportional to gas volume at a constant temperature | Boyle's Law |
The law that states the total pressure of a mixture of gases is equal to the sum of the partial pressures | Dalton's Law |
6.02 x 10^23 is the | Avogadro's law |
According to Boyle's law, if the volume of a gas is halved, the pressure is _____. | Doubled |
Which law explains why a large volume of gas is released from a pressurized cylinder? | Ideal gas law |
This application describes what Gas law:Squeezing the Ambu bag cause an increase in pressure and decrease in the volume | Ideal gas law |
This application describes what Gas law:During inspiration when breathing spontanously,intrapulmonary pressure falls and volume increases. | Ideal gas law |
This application describes what Gas law:During normal expiration, intrapulmonary pressure and volume decreases. | Ideal gas law |
This application describes what Gas law:Measurement of functional residual capacity (FRC) by body plethysmography | Ideal gas law |
1 atm = ___ psi | 14.7 |

According to Law of LaPlace, ___ may be defined as the internal force generated by a structure. | tension |
According to the Law of LaPlace that formula for cylindrically shaped structures | T = PrT = Wall Tension P = Pressure of liquid w/in the cyclinderr = radius |
According to the Law of LaPlace, as radius expands, the tension in the wall structure will ___. | Increase |
According to the Law of LaPlace, as tension in the wall is proportional to the ___. | radius |
Which law explains: The larger the radius, the higher the wall tensions and the more likely the vessel will rupture. | Law of LaPlace |
Give 4 places where the law of LaPlace applies | a blood vessel, an aortic aneurysm, and the ability of capillary vs. vein to withstand pressure, and the left ventricle. |
Which law states that the greater the tension in the ventricular wall at end-diastole, the greater the stroke volume? | Frank-Starling law |
The law of LaPlace related to ARDS (with no normal surfactant) the smaller alveoli radii will have ______ pressure. | higher |
The law of LaPlace related to ARDS (with no normal surfactant) the smaller alveoli radii will empty into larger alveoli, causing ___. | Atelectasis |
What law explains why normal small alveoli do not empty into large alveoli. | Law of LaPlace |
