We model the human pulmonary system as a pair of lungs, represented by ellipsoids, connected through bronchi to the trachea, into which inhaled gases can flow. The color, varying from light blue to red, tracks the temperature changes of the inhalant gas from its initial value until it reaches a final equilibrium temperature.


You can select the body temperature (average normal is 98.6 °F) and the temperature of the inhalant (for example, nitrous oxide). Moving the "time" slider gives an approximate picture of the variation of the inhalant temperature. (For simplicity, we neglect the gradient in temperature as the breath moves from the nose or mouth into the lungs.)
