Umntwana uyisiqhamo sothando lomntu kunye nomfazi, kwaye kuyamangalisa ukuba iiselini ezimbini zesini zidibanisa, zanda, zitshintshe kwaye ziba ngummangaliso omkhulu kuMhlaba-kumntu. Umama ngamnye unomdla kwi-intrauterine ukuphuhliswa komntu ahamba phantsi kwentliziyo yakhe.
Ixesha lokuphuhlisa i-intrauterine
Kukho ixesha eliqela lokuphuhliswa kwe-intrauterine lomntwana. Isihlandlo sokuqala kukubunjwa kwe-zygote, xa ngexesha lesenzo sesondo sesingena kwisisini, ke kwii-tuberpian tubes, apho badibana khona neqanda kwaye i-spermatozoon enamandla kunena kuyo kwaye ukuhlanganiswa kwe-nuclei yabo kwenzeka. I-zygote esiphumela iqala ukwahlula kwaye iqhubekele phambili kwisigxina se-uterine ngenxa yokuphambana kwamathambo e-fallopian. Ngenxa yesahlulo kwiqanda lomntwana, amaqabunga ama-embrionic ama-3 akhiwa, apho izitho kunye nezicubu ziya kwakha. Ngomhla wesi-5-6, umbungu usungulwa kwisibeletho. Ixesha lesibini libizwa ngokuba yi-fetal kwaye lihlala kude kwiiveki eziyi-12. Ngeli xesha, i-embryo ihlanganiswa ne-villi, ezinye zazo zikhula zibe ngodonga lwe-uterine kwaye ziguqulwa zibe yi-placenta. Inkqubo yokufakwa kwamatyala igqitywa ngeenyanga ezine. Ukususela ngeveki ye-12 isigaba sokukhula sesisu sokuqala kokukhula, kuba ukususela ngoku kwi-embbryo kuthiwa ngumntwana. Ixesha lokumiswa kunye nokufakwa kwamatyala kuthathwa njengethuba elibalulekileyo lokuphuhliswa kwe-intrauterine, kuba ngeli xesha ama-embryo ayabakhathalela ngokukhethekileyo amanxeba
Uphuhliso lwe-intrauterine ngeveki
Ngexesha lokukhulelwa ngokupheleleyo kunye nomntwana, kukho utshintsho olubalulekileyo olukhokelela ekubunjweni kwamalungu kunye nokwahlukana kwezicubu. Izigaba ezibalulekileyo zokuphuhliswa kwe-intrauterine zilandelayo:
- kwiiveki ezi-4, i-embryo ifakwa kwisisu;
- Iiveki ezili-12 inkqubo yokubeka
- ngeveki 13 unako ukugqiba ngesondo somntwana ongakazalwa;
- ngeveki le-14 ilungu lokuphulaphulwa lenziwa kwaye umntwana usuva ilizwi likaMama, uqonda umculo;
- ngeveki-16, umntwana uqala ukuhamba;
- ngeveki 18, ii-reflexes zangaphakathi. Ingane inokugwinya i-amniotic fluid, ilise umunwe, vala amehlo akhe ekukhanyeni okukhanyayo kunye nokukhwankqisa kwe-cornea yelihlo;
- ngeveki lama-20 umntwana ufikelele kwisayizi esanele ngokwaneleyo, ukuba umama wakhe uqale ukuziva uvuselelekile;
- Ngesonto le-24 umntwana uvela ngaphandle, kodwa amalungu akhe awaye aqokelele ngokwaneleyo, kwaye kwimeko yokuzalwa, umntwana onjalo akavumelekanga;
- ngeveki 25, ilungu lombono kunye nomntwana lwakhiwa, nokuba ku-utero ukwazi ukuphendula kwisisombululo esilawulayo;
- Umntwana ozalelwe ngeveki yama-28 ekuboneleleni ngononophelo olufanelekileyo lwezonyango uyakwazi ukusinda. Ukususela kwiveki yama-28 ukukhula okunamandla komntwana kwisisu kuyaqatshelwa kwaye ukubunjwa kwamalungu angaphakathi kuza kuphele;
- kunye neiveki ezingama-37 zokukhulelwa kuthathwa njengento epheleleyo kwaye umntwana ulungele ukuzimela ngokuzimeleyo kwimeko.
Ukufundwa kwentuthuko ye-intrauterine fetal - ultrasound
I-Ultrasound yindlela echaphazelekayo evumela ukuba uqaphele ukuphuhliswa kwe-intrauterine yengane iiveki. Umbungu uqala ukuboniswa ngeveki yesi-5, xa ihambele kwisigodlo se-uterine. Kwiiveki ezi-6 ukuya ku-7 uya kubona intliziyo. Kwiimviwo ze-9-13 neye-19 ukuya kweye-22 ukuya kweye-22 ukuya kweye-22 ukuya kweye-22 ukuya kweye-22, ukulawulwa kwe-ultrasound kwenziwa, apho ukubunjwa kwezitho zangaphakathi, umsebenzi wabo kunye nemilinganiselo. Ukuba kuyimfuneko, i-ultrasound inokuphindaphinda kaninzi.
Kumele kukhunjulwe ukuba ngexesha lokukhutshwa kwezakhiwo zonke zenzeke kwaye naluphi na ukungalingani kumzimba kamama (izifo, imikhwa emibi, ukusebenza ngokomzimba) kunokuchaphazela kakubi ukubunjwa komntwana ozayo.
