Ngethuba lokubanjwa kweeveki ezi-7 , imfuyo encinci inenkqubo yokwakha ngokukhawuleza. Umntwana usenomsila, kwaye inhloko isenkulu ngokuthelekiswa nomzimba, kodwa amehlo sele sele esondele ngakumbi kwibhulorho yepumlo kunye neentloko ziqala ukwenza, iris ikhula kwaye i-pigment ibonakala kwi-retina yamehlo.
Ukuphuhliswa kwe-fetus kwiiveki ezi-7 zokukhulelwa
I-embryo yona yaqondisa kancane - ayikho into efana ne-arc. Eminye imilenze kwaye ilawula ukwazi ukubona iminwe, kukho ukuyila kwamagxa kunye neengaphambili, isiqhamo sisazi indlela yokubopha izibambo kunye nezikhwebu. Umlomo ophezulu kunye namacwecwe omtshini nawo ayahlukana, indlebe yangaphakathi neyangaphandle iyakha.
Ukuphuhliswa kwezitho zangaphakathi kunye neenkqubo zibuyele ngokugcwele. Ngokomzekelo, intliziyo yomntwana isele i-atrium ekunene neyekhohlo kunye neveki yesixhenxe kukho ukwahlula kwentliziyo ibe yikamelo eli-4, ngoko lilungele "ukuqhuba" igazi elijikeleze ithole lonke. Ukongezelela, kukho inkqubela ebonakalayo kwinkqubo ye-vascular, kubandakanywa ukwakheka kwemithambo emikhulu yegazi. Ngokukhawuleza intliziyo iza kuba kwindawo yayo, kodwa ngelixa liphakathi kwinqanaba le-thoracic kwaye lihamba phambili.
Kwakukho ukwahlula kwengqondo kwii-hemispheres ezimbini kwaye ngoku amasebe amacandelo awo aqala ukusebenza. Inkqubo ye-nervous ibuye iphuhlise ngokukhawuleza ngokukhawuleza, sele iqulunqwe ngokupheleleyo.
Kodwa ngoku ukuphuthuma okukhawulezayo komntwana. Ukubunjwa kwenkqubo yeethambo kuqala kunye nokwakhiwa kwe-epidermis. Musa ukugubha emva nangamalungu angaphakathi: i-bronchi ikamva, imiphunga, amathumbu, izintso, iingqungquthela ze-endocrine ziyaqhubeka zikhula. Kugqityiwe ngokupheleleyo ukubunjwa kwamathumbu amakhulu, isithasiselo, iilingi zamathambo esibindi. Kwi-pancreas, uphuhliso lwe-insulin luqala.
Kule veki yokukhulelwa, ukuchongwa ngokwesini kuya kuphela ukuphela: izilwanyana zesini ziza kuphuhliswa kwii-ovari okanye kumathambo, kwaye ekugqithiseni okubangelwa yi-perineum izitho zangasese zangaphandle ziza kwenziwa. Kodwa i-ultrasound ayikwazi ukucacisa ngesondo lomntwana.
Usana selude lude, ukuba silulinganisa kunye neveki zokuqala - i-KTP yayo - ubungakanani be-coccyx-parietal malunga ne-13 mm. Kodwa kusekho isisongelo sokukhulelwa kwesisu, ngoko umama kufuneka azinyamekele.
Ukutshintshiselwa kwe-Uteroplacental
Le veki, inkqubo yokubunjwa kwetambo yekhondlo igqityiwe ngokupheleleyo kwaye utshintshiselwano lwe-intterlacental phakathi koomama nosana lulawulwa. Umntwana uxhomekeke ngokupheleleyo kuwe, ephefumula kwaye uzama ngoncedo lwezinto ezingena egazini likaMama - akudingeki ukulibala ngalo. I-placenta ekugqibeleni iba yimbi, ukuze ilungele ngokupheleleyo ngeveki ye-12 yokukhulelwa. Isithintelo esivela kwi-placenta kukukhusela umntwana, okwenene, kungekhona kuzo zonke "ukucasula". Ukongezelela, ngeveki yesixhenxe, iplagi yombumba ivela kwi-layer uterine layer, ehlanganisiweyo. Yona "isango" elivala ukufikelela kwihlabathi langaphandle kwilizwe lomntwana. Iplagi yomdaka iya kushiya ixesha elide ngaphambi kokubonakala kwayo kwaye iya kuba ngumqondiso wokuqala wokuzalwa okuzayo.
I-placenta yindlela yokulungiselela umsebenzi wokuvelisa ama-hormone, okwenziwa kuze kube yinto yomzimba ophuzi. Ukuba lwakhiwa kwaye lukhula ngaphandle kwemingcipheko kunye nokuphulwa komnye, akufuneki ukuba umntu akhathazeke, kodwa phantsi kweemeko ezithile, ezi nkqubo zinganciphisa, eziza kubandakanya ukuphulwa kwemvelaphi ye-hormone eyimfuneko ukugcina umntwana. Iqela elinobungozi obuphezulu libandakanya abasetyhini abasuleleke kwizifo ezithathelwanayo kulo xesha, sele besandula ukukhipha isisu, banokukhubazeka kwesisu kunye nalabo ababenokungaqhelekanga kwimihambo kunye nezifo zezesondo.
Ukuba awukabhaliswanga, le yithuba elifanelekileyo le. Kufuneka udlule zonke iimvavanyo iimviwo ezifunekayo, ezibandakanya uhlalutyo lwe-Rh-conflict. Qinisekisa ukuba udibene neengcali ukuba unesifo se-endocrine.
Utshintsho kumfazi kwiiveki ezisixhenxe zokukhulelwa
Ngeveki yesixhenxe yokukhulelwa, iinjoro ze-asola ziba mnyama, kwaye umgca omnyama ungabonakala kwisisu. Ibhinqa lingaqala ukuba neentlungu kwisisu esisezantsi kunye namacaleni ngenxa yokukhula kwesibeleko.
Njengoko umthamo wegazi ukhuphuka, unokunyuka emilenzeni, okubangelwa ukuvuvukala, kwaye ngamanye amaxesha kubonakala ngathi kunqongophala kwe-oksijini kunye nomfazi okhulelweyo angakwazi ukuphazamiseka.
Zonke iimpawu zokukhulelwa, ezibandakanya i-toxicosis yokuqala, zigqatswa ngokucacileyo ngakumbi. Umama ozayo unokuba nomsindo, ukulala, ukhathala-kufuneka ulale ubuncinane kwiiyure eziyi-8 ukuya kwemihla, kuba umzimba usebenza nzima kwaye ufuna ukuphumla. Musa ukulibala malunga nokusetyenziswa kwamavithamini kunye nokutya okunempilo. Kungcono ukukhetha ukutya okunempilo, kufuneka uphephe ukutya, ukucwenga, ukucoceka nokutya. Ukufumana isisindo ngokunyanisekileyo kuya kuqala, kwaye kungekudala kuya kuba ne-tummy. Kodwa akudingeki ukuba ushiye amafutha kunye ne-carbohydrate (ngokwemvelo, incedo): ngaba ngababoneleli bamandla kunye namandla kumntwana ngokukhula kwakhe nokukhula okuqhelekileyo.
Iiveki ezi-7: iingcebiso kubafazi abakhulelweyo
Kungangoko kunyanzeliswa ukuba uhambe, hambani emoyeni omtsha, wenze i-aphoyintimenti ye-gymnastics kwabasetyhini abakhulelweyo, ngokufanelekileyo, ukusuka kwimidlalo kuyimfuneko ukunqaba.
