Respiración

La respiración comprende de dos fases. La primera es la fase de inspiración. La inspiración permite que el aire fluya hacia los pulmones. La segunda fase es la de expiración. Ésta consiste en la expulsión de gases de los pulmones. Durante la inspiración, los músculos intercostales y el diafragma se contraen, permitiendo que el aire penetre en los pulmones. Durante la expiración, los músculos utilizados para la inspiración se relajan haciendo que los gases sean expulsados de los pulmones.
