La cage thoracique, compos\u00e9e des c\u00f4tes et du sternum, agit comme une structure protectrice pour les poumons et le c\u0153ur. Elle se dilate et se contracte \u00e0 chaque inspiration et expiration.<\/p>\n<ul>\n<li><strong>Inspiration :<\/strong> Les muscles intercostaux et le diaphragme se contractent, soulevant la cage thoracique et augmentant son volume. Cela permet \u00e0 l&rsquo;air d&rsquo;entrer dans les poumons.<\/li>\n<li><strong>Expiration :<\/strong> Les muscles se rel\u00e2chent, diminuant le volume de la cage thoracique et expulsant l&rsquo;air des poumons.<\/li>\n<\/ul>\n<h2>Importance des Mouvements de la Cage Thoracique<\/h2>\n<p>Une bonne compr\u00e9hension des <strong>mouvements de la cage thoracique<\/strong> permet aux \u00e9l\u00e8ves de mieux appr\u00e9hender les sciences d&rsquo;\u00e9veil.
