Ukuze siqonde le ngxaki enzima, makhe sijonge ukuzalwa komntwana ngeentsuku.
Inkqubo yokuzalwa komntwana
I-Conception iyenzeka emva kokuqala kokuvuthwa, okuthi, njengomthetho, kwenzeka phakathi kwimijikelezo yokuya esikhathini. Iqanda elivuthiweyo lishiya i-ovary kwaye liqala ukunyakaza kwalo kwiphubhu ye-fallopian. Ukufakelwa kwemfuyo kunokwenzeka emva kweentsuku ezingama-3-7 emva kokuhamba. Ukuba ngeli xesha ixesha lesondo liza kwenzeka, i-spermatozoa emva kokunyuka kweeyure eziliqela iqala ukuhamba kunye nendlela yokulala yesini ukuya kwiqanda. Ukuze ukuchumisa kwenzeke, akafunanga nje ukufikelela kwi-ovum, kodwa kwakhona ukuba anqobe igobolondo layo.
Ukususela ekungeneni nasekuxhumeni kwe-spermatozoon kunye neqanda, usuku lokuqala lokukhulelwa luqala. Amaseli angamadoda namabhinqa aguquka, enza i-zygote yeeyure ezilishumi elinambini - i-embrylu e-unicellular, esele inezo zonke iifom yezofuzo ezimelelwe ngama-chromosomes ephindwe kabini kubazali.
Ukubeleka komntwana esibelethweni kuhambelana nokuqhubela phambili kwe-zygote kwisibeleko. Le nkqubo iphela ngomhla wesithathu ukuya kweyesithoba. Ekubeni i-tube ye-fallopian ihlanganiswe ne-cilia ekhethekileyo, oku kunceda ukuhamba kwe-zygote.
Kanye kanye nale nto, ngokukhawuleza emva kokuchumisa, i-blastogenesis iqala - i-embryo iqala ukwahlula. Ngenxa yoko, kwi-embryo ye-unicellular iba yi-multicellular (morula).
Malunga nomhla wesixhenxe, iya kuphinda ishintshe isakhiwo sayo, ngokutshintshwa ngokutshintshile ibe yi-blastocyst - imeko efanelekileyo yokungeniswa ngempumelelo kwi-endometrium yesisu.
Ukufakelwa kwi-uterine mucosa kukuqala kokuphuhliswa kokuqhubeka
Ekupheleni kweveki yesibini, ukubunjwa ngokubanzi kwamalungu angaphakathi kuqala. Kwaye ngomhla weshumi elinesibhozo uqala ixesha lesibini ekuphuhlisweni kwexesha elizayo lomntwana .
Emva kokuvavanya izigaba eziphambili zokuzalwa komntwana, unokuqiniseka ngokuqinisekileyo ukuba ukuvela kobomi obutsha ngummangaliso kangangokuba asisoze sazimela.
