    En este artículo simulamos la dinámica del transporte de CO2 en los sacos alveolares pulmonares. Usando el método Euleriano-Lagrangiano arbitrario, se pudo controlar el movimiento del dominio para una respiración normal y forzada. El fluido de gas de ambiente inhalado y las concentraciones de CO2 fueron aproximadas por las ecuaciones de Navier-stokes y la ecuación de convección difusión, el stress paras diferentes maniobras fueron calculadas en tiempos iguales. La expansión para la maniobra normal y forzadas fueron representadas como el 9y 90% de la geometría inicial. Las diferencias de la cantidad de CO2 fue 73x10

    We simulated the dynamics of CO2 transport in the alveolar sacs of the human lung. Using Arbitrary Lagrangian Eulerian (ALE) framework, we control the movement domain for a normal and fast maneuver. The fluid of room air inspired and CO2 concentrations were approximated by Navier-Stokes and convection diffusion equations; the stress-stretch in the wall for different volumes were quantified in equal time of respiration. The expansion for a normal and forced maneuver were represented as 9 and 90% to the initial geometry. The difference of the CO2 was 73x10
