Abstract
The dynamics and thermodynamics of gas flow in human respiratory system is discussed. Approximating the time dependence change of intrapulmonal pressure in a harmonic law the characteristic timescales for breathing process, as well as the work and the heat loss rate by respiratory system are estimated. The role of surfactants in breathing of warm-blooded and cold-blooded animals is dis­cussed.
