The respiratory system exchanges oxygen and CO2 by inhaling and exhaling air.
The respiratory system is part of the vital function of nutrition because we need oxygen to use the energy.
Your respiratory system
Para el proyecto de fin de unidad. Siguiendo los pasos de este vídeo se puede construir un modelo de caja torácica con pulmones. El globo de abajo hace las veces de diafragma haciendo vacío para que los pulmones se hinchen. Al soltar el Globo/diafragma, la presión se recupera y los pulmones se vacían.
The purpose of this blog is to host a compilation of different texts and activities which can be used for an EFL class, as well as general resources. During the following weeks I'll post regularly different resources learnt at uni as well as other things I’ve seen as a student or within less formal environments, and hopefully I’ll do it both in Spanish and in English. In addition there will be useful links to other blogs and compilations.
