Iveki engama-13 ihamba ngeeveki ezili-11 zokukhulelwa. Ngeli xesha, umntwana ukhula ngokukhawuleza. Ubungakanani bomzimba wakhe, ukubala ukusuka kwithsaba ukuya ekupheleni kwe-coccyx, bukho kwi-6.6-7.9 cm, kwaye ubukhulu bayo buyi-14-20 g.
Umzimba womfazi okhulelwe ushintsha njani?
Kwiiveki ezili-13 ezithintekayo, i-uterus iyanda kakhulu ngobukhulu. Umama wesikhathi esizayo unokumfumana ngokuzimela phantsi kwesisu sakhe, 10 cm ngaphantsi kwintonga. Kule meko, isibeletho sigcwalisa ummandla we-hip kwaye uqhubeka ukhula phezulu, uhamba kwisigxina esiswini. Umfazi unomvakalelo, njengokungathi ngaphakathi ngaphakathi kukhula ibhola elithambileyo.
Njengomthetho, ekukhulelweni kweveki ezili-13 ezinqamlekileyo, umfazi ubeka ubunzima. Kodwa, ukuba owesifazane okhulelweyo uhlala ehlushwa yi- toxicosis , ebonakalisa isicaphulo kunye nokuhlanza, mhlawumbi ubunzima bakhe buncipha.
Ngenxa yokunyuka kobukhulu bomntwana, kumanqanaba okuqala amabhinqa, amanqaku atyula angabonakala emzimbeni. Iziganeko zeendawo ezivela kwindawo yendawo ziyizintlu, emacaleni, esifubeni somfazi okhulelweyo.
Umntwana ukhula njani kwaye akhule?
Kulo xesha lokunyuka kwamatye ama-13-14 kweeveki ukuba isigaba sokuphuhliswa kwamabrionic siphela kunye nexesha elide lophuhliso lomntwana luqala. Okwangoku, kukho ukukhula okukhawulezayo kweethambo, kunye namalungu omntwana, asele ayenziwe ngokupheleleyo. Ixesha lokukhula okusebenzayo lihlala kwiiveki ezingama-24. Xa kuthelekiswa neiveki ezi-7 zesisu, ubude bomzimba obushushu buphindwe kabini. Ukwanda okukhulu kunani lokukhula komntwana kubonakala kwiiveki ezi-8-10 zokukhulelwa.
Ngexesha elifanayo kwixesha leiveki ezi-13 ukuya kwe-14, le nto ichazwe: ukukhula kwezinga lentloko yehla kuyahla xa kuthelekiswa nokukhula kwetraki. Ngeli xesha, ubude bentloko buqingatha ubude be trunk (ukusuka kwithsaba ukuya emacaleni).
Ubuso bomntwana luqala ukufumana iimpawu zomntu omdala. Amehlo ngolu hlobo, olubonakala kumacala omabini entloko, ngokukhawuleza luqala ukusondelana, kunye neendlebe zihlala kwindawo yazo eqhelekileyo, ezantsi.
I-genitalia yangaphandle sele iqulunqwe ngokwaneleyo, eyenza kube lula ukunquma ngesondo somntwana ozayo.
Amathumbu, aqale aphuhliswe njengento encincileyo yentambo yomzimba, ikhona ngaphandle komzimba kwaye ngokukhawuleza ibuyele emntwaneni. Ukuba oku kungenzeki, phuhlisa i-omphalocele (i-hernia-hernia). Le ngxaki ayinqabile kwaye ivela kwixesha eli-1 kwi-10,000 ukukhulelwa. Emva kokuzalwa, umntwana usetyenziswe, emva koko uphila ngokupheleleyo.
