En la clase de biología realizamos el aparato de Funke utilizando una botella cortada a la mitad, un globo, cinta,guantes de latex y pajitas o cañito de plástico. Este dispositivo representa el sistema respiratorio; el guante se coloca en la parte de abajo de la botella de plástico cortada a la mitad y representa el diafragma, cuando el diafragma sube y las costillas vuelven a su lugar, el torax se achica y empuja a los pulmones que expulsan el aire por las vias respiratorias hacia afuera. El aire ingresa por las vías respiratorias (fosas nasales,faringe,laringe,traquea) (cañito de plástico) y llega a los pulmones (globo) que se infla.
