Isakhiwo sesigxina somntu. Iimpawu zeAnatomical

Isakhiwo sesigxina somntu sihluke ngokuthe ngqo kwindlela yokwakhiwa kwezakhiwo ezifanayo ezifana nezinye iintlobo zezilwanyana zamammalia. Isisu esiswini (isicathulo se-abdominis) okanye isisu esiswini sithathwa ngokuba yi-spacious fascia, eboshwe ngasentla ngefayile yefayili, ukusuka kumacala omabini kunye nakusaphambili yimisipha ebanzi (i-musculi obliqui et transversus abdominis) yesisu, nangemva- . Ngaphantsi kwayo, oko kukuthi, isigxoba esiswini okanye esiswini, siyadlulela ngokukhawuleza kwisincinci esincinci. Esikhundleni sesithuba esiswini sinezixhobo ezahlukahlukeneyo zangaphakathi kunye ne-peritoneum ebenxibayo, kunye neentonga ezinkulu zeethambo kunye neentsholongwane.

Isakhiwo sesigxina somzimba somntu sifundwe ngokubanzi kwiziko lezonyango eziphezulu, ekubeni izifo zezitho ezikuyo ziimeko eziqhelekileyo zentsholongwane kwizonyango. Kuvela kolwazi olunzulu lugqirha lolo hlobo lomzimba womzimba njengoko isakhiwo sesisu esiswini esithile ukuba ngamanye amaxesha ubomi babantu abangabanye abantu abaswele uncedo lwakhe buxhomekeke.

Isakhiwo sezitho zesisu esiswini sisichazwe kukuba ininzi yazo ihlanganiswe ngomlenze omncinci we-serous obizwa ngokuba yi-peritoneum. I-peritoneum isakhiwo esicacileyo nesincinci esicacileyo sesisombululo esinomlinganiselo omkhulu weempawu eziqhekekileyo kwaye zihlanganiswe ngaphakathi nge-single-layered flat epithelium, oko kukuthi, i-mesothelium. Le membrane elincinci ye-serous inomthamo omkhulu kwaye unqabileyo wokuxhatshazwa. I-Serous fluid, evelisa ngokwaneleyo i-peritoneal mesothelium, igubungele ubuso bazo zonke izitho zangaphakathi, iququzelele ukuxabana phakathi kwabo. Ndiyabulela kule propati eyingqayizivele ye-peritoneum, umntu onempilo akanakuva ulungelelaniso kunye naluphi na utshintsho kwisigxina sakhe esiswini. Nangona kunjalo, ngeziganeko ezivuthayo, xa i-outusion yangaphandle iwela kumaphepha e-peritoneal, ivakalelwa intlungu ephilileyo kwaye ingapheliyo. Kwiinkqubo ezivuthayo, i-peritoneum inokudala iipiksi ukukhawulela ukusasazeka kwintsholongwane kwisigxina esiswini.

Isakhiwo sesigxina somzimba sabantu sinye kummeli ngamnye weHomo sapiens. Kuphela kunokungafani ngexesha elide lobomi bakhe. Ubuntwaneni kukho impawu ezizodwa, kubantu abadala - zabo. Kwakhona kukho ukungafani phakathi kwesigxina samadoda nesisu esiswini. Kwimimandla yesiqingatha esomeleleyo, esi sithuba sivaliweyo, kwaye inxalenye yesetyhini yabemi ayinjalo, kuba ngeengcambu ze- fallopian zixubusha kunye nesigxina se-uterine, kunye ne-vagina kunye nommandla wangaphandle.

Amalungu kwisisu esiswini okanye esiswini angabholwa nge-serous membrane evela kumacala onke okanye ngokukodwa. Ezinye zazo azifihliwe yi-peritoneum nonke. I-peritoneum, edibanisa iindonga zesisu, ibizwa ngokuba yi-parietal peritoneum, oko kukuthi, i-parietal, kunye neminye imigca yezona zitho zangaphakathi zibizwa ngokuba yi-visceral okanye yangaphakathi ye-peritoneum. Ngoko ke, xa sithetha ngokubanzi, sinokuthi isakhiwo somzimba wesisu asisona nje isithuba esinjengomlenze phakathi kweparietal (parietal) kunye ne-visceral (intestinal) amaqabunga, ezele i-aseptic serous fluid.

Kwi-peritoneum, ezi ndawo zilandelayo zikwahluke, ezibizwa ngokuba yi-millery. I-Mesentery, okanye iphindaphindiwe, iifetrical peritoneal sheets, apho intlungu encinci ngaphandle kwe-duodenum, inkqubo yoluhlu, i-transverse kunye ne-sigmoid i-colon ye-intestine enkulu inqunyanyisiwe ukusuka eludongeni lomva lwesisu esiswini.
