Moderkagen er et midlertidigt organ, som giver n\u00e6ring til dit foster under graviditeten. Udviklingen af dette organ starter f\u00e5 dage efter befrugtningen.<\/strong><\/p>\n

Moderkagen er p\u00e5 l\u00e6gesprog kendt som moderkagen<\/em>. Det er et unikt organ, fordi det indeholder genetisk materiale fra to individer - fosteret og den gravide kvinde. Moderkagens overordnede opgave er at *udveksle kredsl\u00f8b mellem fosteret og den gravide kvinde. Det betyder, at moderkagen s\u00f8rger for, at fosteret kan udveksle ilt og kuldioxid (som vi tr\u00e6kker vejret gennem vores lunger), men ogs\u00e5 n\u00e6ringsstoffer, hormoner og elektrolytter samt fjerne affaldsstoffer. Moderkagen er ogs\u00e5 kendt som livets tr\u00e6 og best\u00e5r af en tr\u00e6lignende struktur.<\/p>\n

Hvordan dannes moderkagen?<\/h2>\n

Tidligt i graviditeten s\u00e6tter embryoet sig fast i livmoderv\u00e6ggen og deler sig. Den ene del vil danne fosteret, mens den anden del begynder at danne moderkagen. Moderkagen kommer til at sidde der, hvor embryoet v\u00e6lger at s\u00e6tte sig fast. Det kan v\u00e6re h\u00f8jt oppe i livmoderen (fundus), i den forreste eller bageste v\u00e6g eller i den nederste del af livmoderen. Efterh\u00e5nden som graviditeten skrider frem, og livmoderen vokser, har moderkagen en tendens til at bev\u00e6ge sig opad. Hvis du har en moderkage, der ligger lavt ved din rutineultralyd (omkring 5%), betyder det derfor ikke, at den vil ligge i samme position t\u00e6ttere p\u00e5 f\u00f8dslen (omkring 0,5%).<\/p>\n

Moderkagen indeholder sm\u00e5 puljer af den gravide kvindes blod, som skyller ind over de blodkar, der f\u00f8rer til fosteret. Imellem dem er der filtre, som sikrer, at fosteret og den gravide kvindes blod aldrig blandes. Det beskytter fosteret mod mange bakterier, men ogs\u00e5 mod nogle vira. I slutningen af graviditeten lader dette filter st\u00f8rre molekyler som f.eks. antistoffer passere for at hj\u00e6lpe med at opbygge fosterets immunsystem. Blodet kan dog blandes i tilf\u00e6lde af traumer, fosterinversion og invasiv fosterdiagnostik, og det kan v\u00e6re vigtigt, hvis den gravide kvinde har en negativ blodtype, og fosteret har en positiv blodtype.
