Ngisho nangomkhuba ongathinteki futhi kukholelwa ukuthi emasontweni amabili ukukhulelwa kungakaze kwenzeke (ukukhulelwa kwangempela akubheki njengokukhulelwa), umbungu wamaviki amabili usuqala ukuhlala impilo yawo futhi uthuthuke ngokwesikhathi saso. Emva kwakho konke, kusukela amahora okuqala okukhulelwa, iqanda le-fetal liye lathuthuka.
Masinyane emva kokukhulelwa kweqanda, okwenzeka emgodini we-fallopian, i- zygote -iqanda elikhuliswe liqala ukuhlukaniswa . Ngemva kokuhamba ngendlela ye-tube fallopian, ngosuku lwesine iqanda lesisu liphenduka i-blastocyst. Esibelethweni sesibeletho, i-blastocyst isondela endaweni yokufakelwa kweqanda - ukufakwa kweqanda esibelethweni, le nqubo ihlala cishe kwezinsuku ezimbili. I-egg ngalesi sikhathi ihlala embranini yamangcwaba esibelethweni futhi ngosizo lwe-chorionic villi iqanjwe ngokuqinile nesibindi esiswini.
Umbungu wesintu unamaviki amabili ubudala
Umbungu womuntu, oneminyaka engama-2 emasontweni, useBubble Bubble. Akazange ashintshe okuningi emva kwenqubo yokukhulelwa, usuvele esungule izitho zangasese-amnion, i-chorion, i-yolk sac, enikeza zonke izimo ezidingekayo zokuthuthukiswa okuqhubekayo. Emasontweni amabili, i-fetus yenza i-nuclei yeseli ne-cytoplasm. Ekupheleni kwamasonto amabili, i-embryo iba yiqanda elivuthiwe, eline-nucleus eyakhiwe yi-cytoplasm, igobolondo elibala elibonakalayo, futhi "lihlotshiswe" ngomqhele wamaseli e-epithelial.
Amasonto amabili ukubeletha - usayizi wesisu
Njengoba izifundo zibonisa, ubukhulu bombungu ngesonto 2 alisakwazi ukulinganisa, kanye nesisindo somntwana emavikini amabili. Ubukhulu bokuqala, okungatholakala - 0.15 mm, kubhalwe ngesonto lesithathu lokukhulelwa, nesisindo - 1 g - kuphela ngesonto 8.
Ukuthuthukiswa kwe-fetus emavikini amabili
Ukugcina ukukhulelwa, kubalulekile ukulandela umgomo wokuphuza, umbuso wokudla, njll. unikeze ingane yesikhathi esizayo nakho konke okudingekayo ekuthuthukiseni okufanele. Ngaphansi kwezimo ezingalungile zokuthuthukiswa kombungu oneminyaka engama-2 emasontweni angeke wenziwe futhi uzofika kanye nokuya esikhathini. Futhi lo wesifazane ngeke azi ukuthi ukhulelwe. Izimo ezinjalo ezingathandeki kungaba ukucindezeleka kokukhathazeka, umsebenzi womzimba, imithi.
I-fetus ibonakala kanjani njengamaviki amabili?
Ukuze uthole ukuthi, kwanele ukwenza i-ultrasound engabonisi nje ukuthi i-embryo ibukeka kanjani, kodwa futhi isho ngokunembile ubude bokukhulelwa. Naphezu kokuthi i- embryo ingakabonakali , ngesikhathi se-ultrasound kunokwenzeka ukucacisa isilinganiso senhliziyo.
I-embryo isivele isazi izinsuku ezingu-14, izitho zayo ezibalulekile zakhiwa, inhliziyo yayo ingazwakala. Lokhu akuyona nje umbungu. Lona ingane yakho yesikhathi esizayo, ozozalwa emavikini angu-38.
