Ubungakanani bentsholongwane kwiiveki ezili-9 ziyaqhubeka nokwanda, malunga ne-1 mm imihla ngemihla. Ingqungquthela yomntu kwiveki ye-9 yokukhulelwa iqala ukuphakamisa intloko yayo, njengoko intamo yayo isele ikhule kancane. Izandla zakhe sele zide kuneemilenze, zikhula ngokukhawuleza. Kwaye kungekudala umntwana uza kufunda ukufakela izibonda.
I-CT ye-fetus (ubungakanani bombindi ukusuka kwi-coccyx ukuya kwithsaba) kwiiveki ezingama-9 li malunga no-2-6 cm. Ubunzima bayo buvela kwi-2 ukuya kuma-7 amagremu. Ngoku inokuthelekiswa ngobukhulu kunye ne-nuthew nut. Umbungu uqhubeka ulungelelanisa, izitho zaso zigoba kwaye zidibanise, zikhona izikhonkwane zeempiki.
Ngexesha leeveki ezili-9 zokukhulelwa, ubungakanani bomntwana obulandelayo lulandelayo:
- ububanzi bangaphakathi - 33 mm;
- indawo yomzimba ngu-972 mm;
- ivolumu - 16 380 mm cube;
- ubungakanani biparietal - 8.5 mm;
- umthamo we-yolk sac - 5 mm cube.
Ukuphuhliswa kwentlungu kwiiveki ezili-9 ubudala
Isiqhamo kwiiveki ezi-8 ukuya kweye-9 sidlula kwisigaba esilandelayo sokuphuhliswa kweenkqubo ezibalulekileyo kunye nezitho. Unesicerebellum efunekayo ukulawula ukulungelelanisa, i-pituitary gland, evelisa i-hormone yokuqala, uhla lophakathi lwama-adrenals, oluvelisa i-adrenaline, i-lymph nodes. Ukongezelela, izilonda ze-mammary zibekwe kwaye izitho zesini ziqala ukwenza.
Kwiiveki ezingama-9, i-embryo yakha ngokukhawuleza izisipha, amathambo ayo ayomeleza, intliziyo kunye nomsebenzi wesistim somsebenzi kunye nomsebenzi wabo uya kuphucululwa. Intliziyo (izinga lentliziyo) ye-fetus kwiiveki ezingama-9 ngu-170-190 ibhokhwe ngomzuzu.
Kuze kube ngoku, intloko ye-fetal yenza ininzi yobukhulu bomntwana. Nangona kunjalo, ubuso buncwitshisiwe - amehlo asondele kakhulu, avaliwe ngeenkulungwane, ezingayi kuvulwa kungekudala. Umlomo womntwana uba yinkcazo, iimbombo kunye neefolda zivela. Ingane inokugwinya kwaye igubungele. Kwiiveki ezingama-9 intamo yesisu sele ihluka.
Kwaye enye impumelelo ebalulekileyo kule minyaka ikwazi ukuhamba. Kodwa kungekhona ngohlelo lwe-urrogenital, kodwa ngekhanda lomlomo. Ngoku umthwalo kwizintso zabasetyhini ukwanda, kwaye ugijimela kwindlu yangasese kuya kuba nokunye.
Intambo yomthambo, ngendlela, iya kuba yomelele kwaye isomelele, i-placenta iqala ukusebenza, nangona ukude kakhulu imisebenzi iyenziwa ngumzimba ophuzi.
Ukubonwa komfazi kwiveki ye-9
Ukukhulelwa kweli gama kuxhomekeke kwiinguqu ezibukhali zesimo sengqondo, ukhawuleza ukhathala kwaye onke amaxesha aziva elele. I-Toxicosis ngokuguqulwa ngokugcwele-ngakumbi ngokuqinileyo ukubonakaliswa kwayo kwiiyure zasekuseni. Yonke le ngumsebenzi wamahomoni angakabuyiselanga kwisiqhelo emva kokuba utshintsho olunjengokuqala kokukhulelwa.
Ngokubhekisele kwisisu, iiveki ezili-9 zokukhulelwa ubukhulu bayo abuguqukanga nangayiphi na indlela. Isiqhamo sisekuncinci kwaye sihambelana ngokugqibeleleyo kwisisu somama. Kanti iphupha kwisisu lingadibanisa abanye, ngamanye amaxesha lukhokelela ekuvuseni.
Ubushushu ngeli xesha liba lukhuni ngakumbi kwaye lwandise ngobukhulu. Abanye abafazi babona ukubonakala kokugqithisa okungafihliyo kwiimbumba - i-colostrum. Ngoko isifuba sakho silungele ukuhlambalaza.
Kwixesha leiveki ezingama-9 ukuya ku-12, oogqirha banikela umfazi okhulelweyo isalathiso sokuhlalutya ukukhupha izifo. Ngokuqinisekileyo, kungcono ukufumana lo mzekelo kwinqanaba lokucwangcisa ukukhulelwa, kodwa ukuba awukwenzi, hamba ngoku ngoku. Usulelo olusisiseko kwixesha lokukhulelwa kwezi zifo lukhulu kakhulu
Akukho nto ngexesha lobhaliso lwabesifazane ekuboniswaneni kwabasetyhini, abuzwa malunga nokuba khona kwezilwanyana ezifuywayo. Iikati kunye neekati zithwala i- toxoplasmosis - enye yee-agent zokunyusa izifo. Kwaye ukuba unayo ikati, cela ilungu lentsapho ukuba lihlambulule indle kuye-yilapho izifo eziphilayo zilapha.
Kungakhathaliseki ukuba yintoni, zihlengahlengise ukuze ujabulele isikhundla sakho. Cinga nje ukuba ubomi obutsha bukhula kuwe. Kwaye le ncinane encinane incike kuwe kwaye kakhulu ivakalelwa.
