Kubeleka - monga kugwira ntchito mwakhama, ayenera kudutsa nthawi, kuti pambuyo pake thupi la mkazi libwerenso kwabwino. Zitenga miyezi yambiri kubwezeretsa kuyendetsa kwa ziwalo zonse ndi machitidwe. Nthawi yochuluka yochira ndi chiberekero, pamene iye avulala koposa zonse, kuphatikizapo, kuyang'anitsitsa nthawi zonse kwa mayi wodwala matenda opatsirana pogonana ndi kusamalira bwino n'kofunikira.
Chiberekero chimatha msanga pambuyo pobereka
Chiberekero mwamsanga mutangotha ntchito sichikhoza kuchepetsedwa bwino, komaliza kumapeto kwa nthawi yopuma. Mwamsanga mutangotsala pang'ono kubereka, kutalika kwa khomo la khosi (uterine mkati) kumakhala pafupi 11-12 masentimita, kotero kuti ngati kuli kotheka, mutha kuchotsa zotsala za chilonda pachiberekero mwa kuika dzanja pamenepo. Kumayambiriro kwa tsiku lachiwiri, uterine mkati kumachepetsedwa (zongowonjezereka ziwiri zokha), ndipo patapita masiku atatu uterine pharynx imatha kukhala ndi chala chimodzi chokha. Koma kunja kwa uterine kummero, imatseka sabata ndi theka pambuyo pomaliza ntchito.
Kubwezeretsa chiberekero pambuyo pobereka kubwera mwamsanga. Pambuyo pa kubereka, kutalika kwa chiberekero cha uterine chimakhala cha masentimita 15 mpaka 20, kulemera kwake - pafupifupi kilogalamu, ndi kutalika kwake - 12-13 masentimita. Pambuyo maola pafupifupi 24, msinkhu wa chiberekero pansi umachepa, pa tsiku lachisanu ndi chimodzi umatha pafupifupi theka la mtunda kuchokera ku pubis kupita ku nthiti . Pansi pamunsi wa pubic, pansi pa chiberekero umapita kwinakwake pa tsiku la 10. Pakatha sabata itatha ntchito, chiberekero chafupika kufika 500 g, patatha masabata awiri - 300 g, ndipo pamapeto pa nthawi yobereka, chiberekero chiyenera kulemera pafupifupi 55-60 g.
Malinga ndi mmene mimba imachitira ndi kubala, chiŵerengero cha chiberekero chikhoza kukhala chosiyana.
Chimachitika ndi chiberekero pa nthawi yochira
Pamene mitsempha ya chiberekero imakhala, ndiye kuti mitsempha ndi mitsempha yamagazi zimapangidwira, motero, zina zimauma. Maselo omwe amapangidwanso panthawi ya mimba amasungunuka ndi kufa, ndipo maselo otsalira amakhala ochepa.
Pakati pa kubadwa kwachilendo ndizowonda kwambiri, ndi kusintha kwakukulu komwe kumaonekera pamene placenta yathandizidwa ndipo tsopano pali zida zambiri zowonongeka. Mkatikati pakatha kubereka kumakhala pafupi kwambiri ndi magazi ndi zikopa za fetal fetal.
Ngati nthawi yobereka mwanayo ndi yachibadwa, mimba ya uterine ikhoza kukhala yopanda kanthu kwa masiku 4-5. Panthawi imeneyi, phagocytosis, komanso extracellular proteolysis, ndi ofunika kwambiri poyeretsa chiberekero cha uterine.
Zachibindi zoberekera ndi zobisika ndipo zimatchedwa "fuckers". M'masiku oyambirira pambuyo pa kutha kwa ntchito, chiberekero cha uterine chimakhala chamagazi, chifukwa cha kusakaniza kwakukulu kwa magazi, kuyambira masiku 4 mpaka 5 khalidwe lawo limasintha ku serous-yopatulika ndipo mwa iwo amatha kuchuluka kwa leukocyte, ndipo pambuyo pa sabata lachiwiri ndi lachitatu amakhala owala ndi madzi. Pambuyo pa sabata lachisanu, kugawa kwaima.
Chiwalo chamkati (epithelium) cha chiberekero chimabwezeretsedwa pambuyo pa zitsalira za fetalito za fetus, zomwe zikhoza kukhalabe pambuyo pa kubereka. Nthaŵi zambiri, izi zimachitika kumapeto kwa sabata lachitatu, ndipo pamalo pomwe placenta yathandizidwa - mpaka kumapeto kwa nthawi yoberekera.
Mmene mungachepetsere kuchepa kwa chiberekero
Mphuno ya chiberekero imayamba mwamsanga pambuyo pa kubadwa. Panthawi imeneyi, nkofunika kuti pansi pake ndi wandiweyani, ngati palibe, ndiye kuti pangakhale kuchepa kwa mgwirizano wa chiberekero. Pachifukwa ichi, minofu ya chiberekero, yomwe imatuluka kunja kwa khomo lakumaso, ikhoza kuthandizira.
Kuchepetsa chiberekero kumaphatikizidwa ndi zowawa, zomwe zingayambe panthawi yopuma. Kuti apititse patsogolo patsiku loyamba m'mimba, amayi amaika botolo la madzi ozizira ndipo amapereka mankhwala omwe amachititsa kuti munthu asamangidwe. Ngati ululu uli wolimba, ndiloledwa kugwiritsira ntchito mankhwala osokoneza bongo ndi amatsenga, koma nthawi zambiri izi siziri zofunikira. Pofuna kuthetsa mavuto omwe angakhalepo pambuyo pa kuvomereza, malamulo onse oyenera a ukhondo ayenera kuwonedwa.
Pambuyo pa tsiku lachitatu, mzimayiyo amayamba kusuntha pang'ono, zomwe zimathandizira kuthamanga kwa chiberekero.
