Abaningi besifazane ngaphambi kokukhulelwa futhi bengayazi ngokuba khona kwe-chorion, incazelo yalo nokunye okuncane mayelana nesethulo se-chorion. Ngakho-ke, okokuqala, ake sithole ukuthi yini i-chorion. I-chorion yi-membrane yangaphandle ye-embryonic, eyathi ngemva kokudlula isigaba sokuqala se-intuthuko ngayinye ye-fetus, iphenduka i-placenta, eqondiswe "indebe enkulu yokuncelisa" ngosizo lwama-villi amaningi engxenyeni yangaphakathi yesibeletho.
Qaphela ukuthi ijazi elihlambalazayo - i-chorion - yenza ezinyathelweni zakuqala zokukhulelwa imisebenzi eminingana ebalulekile ye-fetus:
- ukuphefumula - kunikeza ukususwa kwe-carbon dioxide, nokugeleza komoya okomama kuya emntwaneni;
- i-trophic - iqinisekisa ukulethwa kwezakhi ezivela kumama;
- i-excretory - ngosizo lwe-chorion itholakala ngemikhiqizo ye-metabolism; Ukuzivikela - ivikela ingane yakho emathonyeni angaphandle.
Isho ukuthini isethulo se-chorion?
Ukuze uqonde ukuthi kuyingozi kangakanani indawo ephansi ye-chorion, sizonquma ukuthi le nkulumo iyini. Ngakho-ke, ukunikezwa kwe-chorion yi-pathology of pregnancy, lapho itholakala engxenyeni engezansi yesibeletho. Ngokwengxenye noma ngokugcwele, i-chorion igwedla i-pharynx yangaphakathi.
Isethulo se-chorion yimbangela
Izizathu zokwethulwa kwe-chorion azicaciswanga, kodwa ezinye izici ezithinta isethulo se-pileous chorion ziyaziwa: i-myoma ye-uterine, izimo eziphuthumayo zesibindi, izibazi ezilandelwayo ngemuva kwesibeletho, ukuvuvukala okungapheli kwesibeletho, isethulo se-chorionic ekukhulelwe kwangaphambili, ukukhipha isisu njalo. Isethulo se-chorion eceleni kwodonga olungaphambili noma ukunikezwa kwe- chorion eduze nodonga olungemva komzimba kungase kuphakame ngenxa yezintambo noma ama-myomas amaningi. Ngakho-ke, ukuvakashelwa kowesifazane wezinkinga zokuzivikela kanye nokuphila okunempilo kuzokusiza ukugwema izinkinga ezihambisana nentshumayelo kanye nemiphumela yayo ngesikhathi sokukhulelwa.
Yeka ukuthi kuyingozi kangakanani isethulo se-chorion?
Lesi sigaba sesethulo se-chorion samukelwa. Isethulo esiphelele se-chorion siyingozi ngokuvala ngokuphelele umphimbo wangaphakathi wesibeletho. Kubizwa nangokuthi isethulo esivelele se-chorion. Ilungiselelo elinjalo liphuma ngokweqile ngenxa yendiza ye-placenta, kanti ingane ngalesi sikhathi iyingozi ye-hypoxia, ngenxa yokuthi ingafa ngendaba emaminithi.
Isethulo esiyingxenye ye-chorion kusho ukuthi kuphela ingxenye ye-pharynx yangaphakathi ivinjelwe. Isethulo esincane se-chorion sisho ukuthi i-chorion ayifuni i-pharynx yangaphakathi, kodwa itholakala ngaphansi kuka-3 cm kuyo.
Ngesikhathi sokukhulelwa, i-placenta ihamba njalo, ngakho-ke ngisho ne-placenta previa yokubeletha ingaba yinto evamile. Ukunikezwa kwe-chorion kuyisibonakaliso esigabeni sokudla, ukubeletha kwemvelo kuleli cala akufakiwe.
Isethulo se-chorion - ukwelashwa
Ukwelashwa kwesethulo akunjalo, into esemqoka ukuhambisana nezinyathelo zokuvimbela. Isivikelo esihle kunazo zonke indlela yokuphila enempilo nokuvakashelwa njalo kudokotela, ukutholakala nokulawula ukubukeka kwama-myomas nama-polyps ngaphambili
I-ultrasound evamile ingasiza ukuqapha isimo ngendlela efanele, futhi i-placenta ingahamba ngokuphepha futhi ivikeleke endaweni ephephile ku-trimester yesithathu, okuzoholela ekubelethweni kwemvelo.
