Comment les plaies cicatrisent-elles?<\/h1>\r\n\r\n\r\n

Tu t\u2019es s\u00fbrement d\u00e9j\u00e0 bless\u00e9(e). Peut-\u00eatre en te coupant avec ton couteau suisse ou en tombant de v\u00e9lo? Tu as saign\u00e9 mais, apr\u00e8s un certain temps, il n\u2019y paraissait plus rien, pas vrai? Ton corps poss\u00e8de donc des capacit\u00e9s d\u2019autogu\u00e9rison. Tu as s\u00fbrement envie de savoir comment il s\u2019y prend pour r\u00e9parer aussi bien les plaies.<\/em><\/p>\r\n\r\n\r\n

Pourquoi les plaies saignent-elles?<\/h2>\r\n\r\n\r\n\r\n

Si tu observes ta peau, tu vois une surface souple et velout\u00e9e. Cette surface cache \u00e0 nos yeux un nombre incalculable de glandes, de vaisseaux et de nerfs. Quand la surface de la peau est l\u00e9s\u00e9e (bless\u00e9e), des vaisseaux sanguins sont souvent touch\u00e9s. Le sang qui circule dans tout notre corps sort alors de ces petits conduits et nous saignons. Si la plaie est petite et superficielle, le saignement est tr\u00e8s r\u00e9duit, mais si elle est plus \u00e9tendue et plus profonde, nous pouvons saigner beaucoup.<\/p>\r\n\r\n\r\n\r\n

SOS!<\/h2>\r\n\r\n\r\n\r\n

Comme tu peux l\u2019imaginer, ce n\u2019est pas bon pour notre corps de perdre trop de sang. C\u2019est pourquoi il active tr\u00e8s rapidement diff\u00e9rents m\u00e9canismes qui veillent \u00e0 ce que le saignement cesse le plus vite possible: dans le sang flottent des \u00abplaquettes\u00bb, qu\u2019on appelle aussi \u00abthrombocytes\u00bb. Ce sont les premi\u00e8res \u00e0 venir s\u2019agglutiner au niveau de la paroi l\u00e9s\u00e9e du vaisseau. La br\u00e8che dans le conduit est ainsi colmat\u00e9e. Un peu plus tard, des facteurs de coagulation arrivent aussi sur le site de la blessure. Ils font en sorte de refermer encore plus solidement la plaie et veillent \u00e0 ce qu\u2019aucun agent pathog\u00e8ne ne puisse p\u00e9n\u00e9trer dans le corps. Le liquide qui s\u2019\u00e9coule de la plaie aide \u00e0 \u00e9vacuer ces microorganismes nocifs. Apr\u00e8s un certain temps, une cro\u00fbte se forme.<\/p>\r\n\r\n\r\n\r\n

Et maintenant, place aux r\u00e9parations!<\/h2>\r\n\r\n\r\n\r\n

Tu ne dois absolument pas gratter cette cro\u00fbte, car elle prot\u00e8ge en surface la plaie qui se trouve dessous. Celle-ci est maintenant un \u00e9norme chantier! Imagine: les tissus sains autour de la plaie commencent de toutes parts \u00e0 former de nouvelles cellules qui viennent se d\u00e9velopper au niveau de la plaie. De fins vaisseaux se forment m\u00eame \u00e0 partir des vaisseaux non ab\u00eem\u00e9s et font en sorte de continuer \u00e0 alimenter la zone touch\u00e9e en sang. Mais le tissu cicatriciel nouvellement form\u00e9 est encore tr\u00e8s sensible et tu dois rester prudent(e) pour qu\u2019il ne se rouvre pas. La plaie se r\u00e9sorbe chaque jour d\u2019environ deux millim\u00e8tres, jusqu\u2019\u00e0 se refermer compl\u00e8tement apr\u00e8s quelques semaines. Apr\u00e8s cela, il faut encore un petit temps avant que plus aucune trace, ou presque, de ton petit accident ne reste visible. Incroyable tout ce que ton corps peut faire, tu ne trouves pas?<\/p>\r\n\r\n\r\n\r\n

\r\n
\r\n

Le savais-tu?<\/strong><\/h2>\r\n\r\n\r\n\r\n

Voici comment tu peux aider ton corps \u00e0 faire gu\u00e9rir plus vite une petite plaie:<\/p>\r\n\r\n\r\n\r\n

    \r\n
  • Avant de toucher la plaie, lave-toi les mains afin d\u2019\u00e9viter le plus possible de v\u00e9hiculer des microorganismes.<\/li>\r\n\r\n\r\n\r\n
  • Rince la plaie sous l\u2019eau courante ti\u00e8de et regarde bien s\u2019il y reste encore de la salet\u00e9 ou des corps \u00e9trangers. Si c\u2019est le cas, enl\u00e8ve-les prudemment avec une pince \u00e0 \u00e9piler!<\/li>\r\n\r\n\r\n\r\n
  • Ensuite, d\u00e9sinfecte bien la plaie avec un spray, un gel ou une pommade vuln\u00e9raire.<\/li>\r\n\r\n\r\n\r\n
  • Pour finir, prot\u00e8ge-la avec un sparadrap et v\u00e9rifie chaque jour qu\u2019elle se referme bien et ne s\u2019infecte pas.<\/li>\r\n\r\n\r\n\r\n
  • Si la plaie est plus \u00e9tendue ou profonde, tes parents t\u2019aideront. Bien s\u00fbr, tu peux aussi toujours venir dans une pharmacie pour demander de l\u2019aide.<\/li>\r\n<\/ul>\r\n<\/div>\r\n<\/div>\r\n\r\n\r\n","protected":false},"excerpt":{"rendered":"
