Il existe deux cavit\u00e9s de chaque c\u00f4t\u00e9 du c\u0153ur, d&rsquo;une oreillette au-dessus et d&rsquo;un ventricule au-dessous. Le c\u00f4t\u00e9 droit du c\u0153ur re\u00e7oit du sang pauvre en oxyg\u00e8ne transport\u00e9 par les vaisseaux appel\u00e9s veines. Il pompe ce sang vers les poumons, o\u00f9 il est enrichi en oxyg\u00e8ne. La partie gauche du c\u0153ur re\u00e7oit ce sang des poumons et le pompe vers tous les organes du corps par le biais des vaisseaux appel\u00e9s art\u00e8res, ramifications de la plus grande art\u00e8re qui part du ventricule aguche, l&rsquo;aorte. Les valves entre les oreillettes et les ventricules sont appel\u00e9es valvules auriculo-ventriculaires (valve mitrale \u00e0 gauche, valve tricuspide \u00e0 droite). Elles emp\u00eachent le sang de refluer dans le mauvais sens. La valve pulmonaire et la valve aortique contr\u00f4lent la sortie du sang des ventricules droit et gauche, respectivement. Les valves s&rsquo;ouvrent lorsqu&rsquo;une certaine pression est atteinte \u00e0 l&rsquo;int\u00e9rieur du ventricule, permettant ainsi au sang de s&rsquo;\u00e9couler dans le poumon (\u00e0 partir du ventricule droit) ou dans le corps et ses organes (\u00e0 partir du ventricule gauche).<\/p>\n<p>Le c\u0153ur est un muscle qui pompe 60 \u00e0 80 fois par minute, toute votre vie. Il a donc besoin de grandes quantit\u00e9s d&rsquo;oxyg\u00e8ne et de nutriments pour fonctionner correctement. Les art\u00e8res coronaires fournissent au c\u0153ur le sang dont il a besoin.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Le c\u0153ur est divis\u00e9 en deux c\u00f4t\u00e9s s\u00e9par\u00e9s par une paroi musculaire (le septum).
