Iyo embryo (kana embryo) inhengo inosimudzira mukati meamai. Mamiriro ehutumbi hwemunhu anowedzera kusvika kumavhiki masere ekuzvitakura. Munguva ino, dhe rinogadzirwa rinopfuurira nzira yekusimudzira kune muviri une zvese zvinokosha zvemuitiro wemunhu. Uye mushure mevhiki masere, embryo inonzi "fetus".
Kubudirira kwemuviri wevanhu
Muchigadziriro chekusimudza, hutumbi hwevanhu hunopfuura nepakati pezvikamu zvakasiyana-siyana (nguva): nguva ye zygote, nguva yekuparadzaniswa kwe zygote , kugadzirisa, nguva yekuzviparadzanisa nekuvandudzwa kwenhengo nemaviri.
Nguva ye zygote (unicellular embryo) inofanirwa kurarama kwenguva pfupi. Kamwe mushure mokunge kwasvika danho rekupwanya mazai - kureva, kuwedzera kwemasero anonzi blastomeres. Zygote yakatove yakakamurwa munzira kubva kuUterine tube kusvika muchibereko. Panzvimbo yegastrulation, embryo ine bhakisikiti yemamiriro emagetsi, musculature, axial skeleton.
Uye zvino kukura kwezvinhu zvose zvidzidzo uye nhengo dzevanhu remangwana. Kubva kuEctoderm, ganda, pfungwa uye chirwere chetsitsi zvinoumbwa. Epithelium yemvura inogona kubuda kubva kumagumo, musimba, epithelium ye serous membrane uye genitourinary system kubva kuma mesermerm, uye martilage, anogamuchirwa uye mapfupa, mapfupa uye chirwere chemasema kubva mu mesenchyme.
Heart of the embryo
Pavhiki yechina yekubata, kutanga kwemoyo kunotanga. Kubva ikozvino, rinoratidzika sehombodo yakadzika. Kutanga kwekutanga kuputika, kukanganisa kwemoyo kwekutanga kwemuviri kunowanikwa pavhiki yechishanu yekuzvitakura.
Mwoyo unoramba uchikura, uye pasina nguva unenge wakava nemakamuri mana-ane maatria maviri uye zvinyorwa. Izvi zvinoitika pavhiki 8-9. Chimiro chemwoyo chakasiyana zvakasiyana nemwoyo wemurume akazvarwa akaberekerwa. Iine hwindo revharivha pakati pekupedzisira nechepamusoro paatrium uye mutambo webhodenene pakati peaorta uye mishonga yemapirmoni. Izvi zvinodikanwa kupa muviri wose uine oksijeni musipo kwekuzvimirira
Yakaderera kuberekwa kwemukomana
Izvo zvinoitika kuti embryo iri shure kumashure kwayo. Izvo zvakagadzirwa mumubhedha zvinenge zvichiitika zvinogona kukonzera kubvisa pamuviri. Zvinhu zvakadai zvinowanzoitika kana mazai asingasviki padanho rekukura kwe fetal, uye chikonzero chinowanzokonzera kupererwa kwepabonde ndiko kusakanganiswa kwechirwere.
Izvo zvipingamupinyi zvikonzero ndezvezera raamai uye kusaputsika uye kubvisa pamuviri mune zvakaitika mumukadzi. Hazvibviri kutaurira kukanganisa doro uye zvinodhaka pamusana wekuvandudzwa kwemukati - izvi zvinogona kukonzera kucherechedza kwekuvandudzwa kwemukati uye kufa kwayo.
