Isilonda sesisu

Njengoba kuyaziwa, phakathi nokuthuthukiswa kwe-intrauterine yengane ezayo ehambisana nezinambuzane zesisu. Lezi zihlanganisa amnion, i-chorion ephathekayo kanye nengxenye ye-decidua (i-endometrium, eqhubeka nezinguquko ngesikhathi sokukhulelwa). Zonke lezi amagobolondo, kanye ne-placenta zakha isambatho sesisu.

Amamama amaningi esikhathini esizayo bacabanga ukuthi i-placenta nesinye isinye futhi sinye. Eqinisweni, lokhu akunjalo. I-placenta iyilungiselelo elizimele elihlinzeka izakhi nomoya emoyeni. Kungenxa yakhe ukuthi umntwana uhlotshaniswa nomzimba womama.

Iyini isambiso sesisu?

Ukuthuthukiswa kwalezi zinambuzane ze-fetal kuqala ngokushesha emva kwenqubo yokufakelwa. Ngakho-ke, i-amnion iyisimbatho esincane semitransparent, esakhiwa ngokuyinhloko ngezicubu ezixhumene nesibindi.

I-chorion ebushelelezi itholakala ngqo phakathi kwe-amnion ne-decidua. Iqukethe inani elikhulu lemithambo yegazi.

I-membrane yesimiso ikhona phakathi kweqanda lesisu kanye ne-myometrium.

Imingcele esemqoka yesibindi sesisu isisindo sayo kanye nosayizi, okuhluka ngamaviki okukhulelwa. Ngakho-ke, ngosuku lwama-30, ububanzi besikhumba sesisu buyi-1 mm bese bukhuphuka ngo-1 mm ngosuku.

Yimiphi imisebenzi yesikhumba sesisu?

Njengoba usho ukuthi yini isambatho sesisu esibukeka ngayo, sizoqonda ukuthi yimiphi imisebenzi yaso esemqoka. Okuyinhloko kubo:

• ukuhlanganisa izinto ezihlukahlukene ezihlinzeka ngezimpendulo zamasosha omzimba;
• ukushintshaniswa kwegesi okuphambene nendawo (ukugcinwa kwe-amniotic fluid composition);
• ukufihla nokuhlanzwa kwe-amniotic fluid;
• umkhiqizo wemikhiqizo yemethamo;
• ukukhululwa kwezidakamizwa ezithintekayo ekunakekeleni ukukhulelwa;
• umsebenzi wokuzivikela (uqaphele umntfwana ekuthelelekeni nokulimala).
