Yingakho bonke oomama bexesha elizayo balinde umzuzu xa unako ukuva intliziyo yomntwana wakho ngoncedo lwezixhobo zamanqanaba ezinje. Ukususela ngeli thuba ubomi obutsha kwisisu sowesifazane buqala ukuhlakulela, kwaye kwiinyanga ezimbalwa kuMhlaba kuya kuba nomnye umntu omnye eMhlabeni.
Kule nqaku, siza kukuxelela indlela intliziyo ikhula ngayo embryo emva kokuqumba, kwaye xa iqala ukubetha ngexesha lokuqheleka lokukhulelwa.
Ukukhula kwe-intrauterine yentliziyo yengane
Umbungu ovela emzimbeni womama, okokuqala, uyaphila, ngoko kufuneka i-oksijini enyanzelekileyo ukunikezela ukugcina umsebenzi obalulekileyo kunye nophuhliso olusebenzayo. Yingakho ukubunjwa kwenkqubo yokujikeleza kwimiba ephambili kwimbutho encinane.
Sekuqaleni kweveki yesibili emva kokuchumisa, xa ubukhulu bombungu obunjwe buphantsi kwe-1 mm, iiseli zayo ziyaqala ukwahlula zibe "zi-embryonic" ezi-3. Ngamnye wabo uya kuthi anikwe imisebenzi ethile kwaye, ngokukodwa, umyinge uya kuthatha inxaxheba ekwakheni inkqubo yokujikeleza, imisipha, izintso, amathambo kunye ne-cartilage.
Ekubeni ngeveki yesithathu emva kokufumba kwe-sperm kunye neqanda, ityhubhu ye-vascular hollow yenziwe, ephikelela ngokupheleleyo umzimba omncinci womntwana. Eli nqanaba libaluleke kakhulu ekuphuhliseni umntwana ozayo, kuba emva kwesikhashana le tube iya kuba yintliziyo yakhe.
Ulwaphulo lokuqala lwequmrhu eliphambili elizayo lwenzeka ngomhla we-22 emva kokuba umbungu usungulwe, nangona kunjalo, ngeli xesha lokukhulelwa alikalawulwa yinkqubo yenzwa. Kulo xesha kwiyeza elithathwa njengesiqalo kwithuba apho intliziyo ibetha kwi-embryo. Emva koko, imihla ngemihla intliziyo encinci iya kugxininisa ngokuphindaphindiweyo, kwaye ngomhla wama-26 emva kokuba umbungu usungulwe, iya kuqala ukupompa igazi ngokwayo kwaye yenze ngesigqi esithile.
Ngeli thuba lokuphuhliswa, intliziyo yengane ezayo idibene kunye kwaye ifana nje nequmrhu elikhulu lomntu omdala. Kule ntsuku e-7 yenkqantosi yokulindela umntwana, i-septum yenziwa kuyo, kwaye isakhiwo esiqhelekileyo siya kufumana emva kweeyure eziyi-10-11. Ngaphezu koko, kulo lonke ukhulelwe, intliziyo yesisu iya kuhlala iguquka kakhulu, iphuhlise kunye namanye amalungu kunye nokubonelela nge-oxygen nezinye izondlo eziyimfuneko.
Zingaphi iiveki intliziyo iqala ukubetha nomntwana?
Njengoko kuphawuliwe kwangaphambili, intliziyo yesisu iqala ukubetha xa kuqhutyelwa i-pulsation yokuqala yokuzibandakanya, oko kukuthi, malunga nomhla wama-22 emva kokuqumba. Ngelo xesha, le nciphiso ibuthathaka kakhulu, kwaye akunakwenzeka ukuyibamba nangona uncedo lwezixhobo zanamhlanje. Ukongezelela, ngeli xesha lophuhliso lombindi, akanalo isantya sentliziyo.
Oomama abanomdla banomdla wokuba i-embbryo sele ibetha njani intliziyo, kwaye le nkqubo ingagqitywa. Kwiimeko ezininzi, oku kwenzeka kwiveki yesine yokuphuhliswa kwengane kwisibeleko sikamama, oko kukuthi, malunga neveki yesithandathu yokukhulelwa. Kulo thuba oogqirha bancomela ukuxilongwa kwe-ultrasound ukuqinisekiswa ukuba umntwana usaphila kwaye ukhula ngokuqhelekileyo.
Ukongezelela, kwezinye iimeko, abafazi banomdla kwiyiphi iveki onokuva ukuba imbungu iyabetha intliziyo, ngaphandle kokusetyenziswa kwezixhobo ezizodwa. Ngokuqhelekileyo, emva kweeveki ezingama-18 ukuya ku-20, uogqirha uyakwazi ukuqonda ngokulula intliziyo encinciweyo kunye ne- stethoscope okanye umtshini weDoppler. Ukwenza oku, ngokusemgangathweni, unako kunye nomfazi ngokwawo, kodwa ngenxa yobukho beengxolo ezidityanisiweyo ukuqhuba ukuxilongwa ngokuchanekileyo kakhulu akukho konke.
