Vanachiremba havatauri maonero anowanzogamuchirwa kuti michero yakawanda mwana ane utano uye akasimba. Chokutanga pane zvose, izvi ndizvo zvinokonzera kushungurudzwa nekuda kwezvinetso zvinogona kuitika kumamai nemwana zvinogona kuitika panguva yekuberekwa. Mwana kubva pamakirogiramu mana kusvika kuashanu anotorwa sewakawanda. Vacheche vanorema makirogiramu anopfuura mashanu vanoonekwa segigantic.
Kukura uye kukura kwema fetus kunobva pane hutano hwemamai anouya uye mamiriro ezvinhu eparcenta, anotsigira ukama hwekuberekwa uye kubereka. Kana kusina kuipa mukati nokunze kwezvinhu, ipapo fetus inokura maererano nezvimwe zvinowanzoitika. Nhasi kune chimiro chekuwedzera kwehuwandu hwematambudziko nekuberekwa kwema fetus makuru. Nhamba yezviitiko zvakadaro ndeyekusiyana kwemashoko kubva pa8 kusvika kune gumi nemasere.
Zvinokonzera mukomana mukuru pakuberekwa
Zvimwe zvikonzero nei mukadzi ane pamuviri angave netsika yemukomana mukuru anogona kunge akasiyana, asi zvakanyanya kuwedzera mukudya kwevakadzi vane pamuviri uye hutano. Paunenge uine pamuviri, unofanirwa kuenzanisa kudya kwaunoita kuitira kuti ugone kusangana nesimba raamai nemwana. Panguva imwecheteyo, zvakakosha kufunga kuti mukadzi wacho haatotungamiri mararamiro anoshingaira sepakutanga, uye simba rake rinoderera.
Zvisina kunaka, kukosha kwomukadzi kunoshushwa nekushandiswa kwezvinonhuwira-zvinonhuwira zvinhu, zvinowedzera chido, kushandiswa kwezvokudya zvakagadzirwa nema carbohydrate zvakanyanyisa, kudya kwekurumidza kudya, apo makorikoni asina nguva yekunyatsogadzirisa. Zvose izvi zvinogonawo kutungamirira kukurudzirwa kwechirwere cheshuga , ichocho ndicho chikonzero chekugadzirwa kwema fetus makuru.
Urefu hwe fetus hunovhiringidzika nemafungiro e morphological ye placenta. Pakati pavo pane kutarisana zvakananga. Kana kuwanda kwepentecenta kunodarika masendimita mashanu, iyo yakawanda uye nzvimbo yacho yakawedzerwa, izvi zvinokonzera kukura kwekukura kwema fetal, sezvo zvirongwa zvemagetsi pakati pekuberekwa uye maamai zvipenyu zvinowedzera. Kunewo hutariro pane nzvimbo ye placenta muchibereko. Zvibereko zvakakura zvinowanzoonekwa kana placenta iripo mushure mechibereko .
Kusadzora kushandiswa kwezvinodhaka izvo zvinovandudza utero-kuputika kweropa kushandiswa, kunowedzera kukudziridza fetus yakakura. Kusvibiswa kwegadziriro ye endocrine yemuviri wemukadzi kunogonawo kuva tsanangudzo yekuti nei ane fetus yakakura. Kukundikana kwomuviri kunokonzera zvirwere zvakadai seshuga uye kuneta. Chibereko chinokura zvisina kufanana, uye kunonoka pasi, nekukurumidza kuwedzera.
Chimwe chikonzero nei fetus inogona kuva yakakura perenashivanie. Iyo inogona kunge yakakura yepanyama kana yehupenyu yekuzvitakura.
Zvibereko zvakakura zvinowanzowanikwa pakati pevana-malschikov. Uyewo, vana vakuru vanowanzoberekerwa vanaamai vaduku vasati vava nemakore makumi maviri uye vakadzi vakuru kudarika makumi matatu nevana.
Kudzivirirwa kwemakumbo makuru
Kudzivirirwa kwekusimudzirwa kwema fetus makuru kunonyanya kukosha kuvakadzi vane zvirwere zvemashuga, chirwere cheshuga chinokanganisa kana kuneta. Muhutano hwose, vanaamai vanotevera vanofanira kuenzanisa kudya kwavo kuitira kuti ienzane nehutano hwekuita. Zvinotarisirwa kuongorora huwandu hweglucose muropa. Vakadzi vane chokwadi chekuberekwa kwakakura vanokurudzirwa kuti vasunungurwe kuti vasarudze kufungidzira uye vasarudze nzira yakakodzera yekuendesa.
