I-Chorion yenye yeembumba ze-placenta. Le nxalenye yesikhawulo se-placental (isiseko sayo esingaphakathi) kwaye idlala indima enkulu kwi-metabolism ye-fetus. Ngokwe-midwifery, ibinzana elithi "intetho ye-chorion" ayiyiyo yonke into enyanisweni, kuba yinto enye yeembalo eziphambili (ngokokuphakathi), ngoko ibinzana elithi "ilungiselelo le-placental" lisetyenziswa rhoqo. Indawo ekhethiweyo yeqhekeza iyinxalenye yesisu okanye inxalenye ephezulu yodonga olusemva. Kodwa ngamanye amaxesha i-chorion ifumaneka eludongeni lwangaphambili lwesisu okanye kwicandelo elingaphantsi lesisu. Kule nqaku, siza kuqwalasela iimpawu zendlela yokukhulelwa xa i-chorion ihlala kwindawo edongeni langaphambili.
Izinketho zendawo yokukhethwa
Indawo ehlala eqhelekileyo yendawo yeqhekeza yodonga oluphezulu emva kwesibindi, kunye nokutshintshela kwiindawo ezizenzekelayo, kunye neli lungiselelo, inqanaba elihle kakhulu lokukhulelwa. Indawo yangasese yodonga oluphambene naso eludongeni oluphambili lubhekwe njengento ekhoyo. Ukuba i-chorion ifumaneka phezulu eludongeni lwangaphambili, ngoko akukho nengozi kwikhosi yokukhulelwa (okungenani u-3 cm ukusuka emqaleni we-cervix).
Ikhoriyoni ibonakala kwangaphambili ekubunjweni kombungu, unembopheleleko yokutya umntwana ozayo emva kweveki ye-13 yokukhulelwa. Ukususela ngeveki ye-13, le misebenzi icingwa yi-placenta. Ekuqaleni, i-chorion inokubonakala kwemimandla encinane ejikeleze umbungu, emva koko le mihla iyanda kwaye iguquke ibe yi-chorionic villi.
Ukunikezwa kweqhosha
Ukunikezwa kwekhriri kwindonga yangasemva okanye udonga lwangaphakathi lubeka ingozi kwisifundo sokukhulelwa. Nika isingeniso esincinci (umda we-placenta uvale ngokukodwa umlomo wesibeletho somlomo wesibeleko) kunye neentetho ezipheleleyo (i-placenta igubungela ngokupheleleyo umlomo wesibeleko somlomo wesibeletho). Abafazi abathandayo bafuna ukuhlolwa okhethekileyo, kuba basengozini yokuqhwaba. Ukuba umboniso wekririon kwenzeka ngaphandle kwodonga lwangaphambili, umngcipheko wokuphuma kwamanzi uphezulu, ngenxa yokuba inxalenye engezantsi yodonga lwangaphakathi lwesibindi ilula ngakumbi kwaye ngokukhawuleza kwaye ihamba ngokukhawuleza ukukhula kweplacenta kunezizathu zokuphuma kwegazi.
Sihlolisise iimpawu zendlela yokukhulelwa xa i-chorion yindawo ejikelezileyo. Kwimeko apho i-chorion itholakala kwisithathu esiphezulu sesibeletho sokukhulelwa akukho nto isongelwayo. Ukuba i-chorion iqhotyoshelwe eludongeni lwangaphakathi lwesibindi, kwisithathu sayo esezantsi, umngcipheko wokuphazamiseka kweplantshi ngaphambi kwesikhathi.
