Uninzi lwabasetyhini ngenyanga yokuqala yokukhulelwa awaziyo malunga neemeko zabo ezinomdla. Ubume kunye nobungakanani besisu esisitshintshiyo asitshintshi. Nangona kunjalo, zonke i-metamorphoses ngeli gama zingaphakathi, kwaye zingekho zangaphandle. Ukuphuhliswa kwembungu kuhamba ngezigaba eziliqela. I-embryo ihamba kancane kancane, iguqula nganye iveki. Akunakwenzeka ukuyilandelela ngokuzimela, kodwa kulula ukucinga kwimifanekiso indlela ubomi obutsha buzalwa ngayo.
Imbungu, i-embryo, okanye i-fetus: iyenza njani
Ixesha lokuthoba libalwa ukusuka kwimizuzu yokugqibela yokuya esikhathini. Kule meko, ukukhulelwa kunye nokuvuthwa kwangaphambili kwenzeka malunga neentsuku eziyi-14 kamva. Iveki yokuqala ibhalwa ukuhamba kwelanga. Kule meko, umzimba womfazi uhlengahlengiswa kwindawo yayo entsha. Kwamaqanda amaninzi, kuphela 1 kuqala ukuvuthwa. Ubungakanani bomhlaba obunamaqanda obumbilini buphela ngokukhawuleza. Iifom ezitsha zoluhlu kwiziko lezicubu ezinqatshelwe. Ngaloo ndlela, akukho mbilini. Ngaphandle kwindlela ye-ultrasound akusoloko kunokwenzeka ukulandelelanisa olu tshintsho.Ukuphuhliswa komntwana: imifanekiso yeentsuku zakhe zokuqala
Ukufikelela kwiinyanga ezi-2, ukukhulelwa kuthiwa yi-embryonic, ngenxa yokuba umntwana uhlala embindi. Ukuphuhliswa kombungu, onokulandelwa ngemifanekiso ethengisiweyo kunye neefoto, kuchaza intlanganiso ye-ovum kunye nesidoda. Isiphumo soxhumano lwabo yindawo ephuzi, ebaluleke kakhulu ngenyanga yokuqala.Kwinqaku! Kwindawo ephuzi ukuba i-estrogen kunye neprogesterone ikhutshwe, enoxanduva lokugcina umntwana.Ukusebenza kwalo mzimba kudibene ne-toxicosis. Ngokuqhelekileyo, emva kokuba yonke imbopheleleko yokugcina umntwana ozayo uyadlula kwi-placenta, zonke iimpawu ezingonakalisayo zeenyanga zokuqala zenkalo echaphazelekayo idlula. Le nkqubo inxulumene neveki ezi-14 ukuya ku-16.
Iimfroshi zezithombe ngeveki: iiveki ezi-1 neye-2
Yonke imihla yexesha elibambileyo linomdla. Emva kwakho konke, imbungu ifumana iimpawu ezikhethekileyo kumntwana wangempela, nangona isisu, njengomthetho, sibukeka kwangaphambili kwaye singaniki ubomi obutsha obuvela kuyo. Iveki yokuqala inxulumene nenkqubo yokuchumisa. Kukho ukudibanisa kweseli yesetyhini kunye nesidoda. Njengomthetho, yonke into ihamba kwi-tube fallopian, kwisebe layo le-ampullar. Kwividiyo engezantsi unokulandela iziganeko ezivela kwimvelaphi yembungu.Thabatha ingqalelo! Iiyure ezimbalwa kuphela kwiintsuku eziyi-1-7 zanele kwiseli yesetyhini ehlanjululwayo ukuba ihlule kwijubane eliphezulu kwi-geometric progression, emva koko ingena kwisibeletho nge-tube fallopian.Emva kokuhlukana, umzimba okhethekileyo wenziwa. Ngaphandle, kubonakala into efana ne-blackberry, njengoko ubona kwelinye lezithombe. Kule nqanaba, imbungu ye-gynecology ibizwa ngokuba yi-morula. Ngomhla wesi-7, ngokuqhelekileyo kufakwa kwi-uterus. Ezinye iiseli zenza i membrane kunye nentambo. Kwezinye iiseli, izitho zangaphakathi kunye nezicubu zomntwana ziza kuphuhlisa. Iveki yesibini yenyanga yokuqala yokukhulelwa iboniswa ukufakwa komninzi kwe-morula kwi-mucous surface of uterus. Umntwana ukhula kwiintsuku 8-14:
- placenta;
- intambo;
- i-neural tube.
Ifoto yabantwana kwisisu ngeentsuku: iiveki ezi-3 nee-4
Nangona ukuba isisu kwisonto lesithathu lokukhulelwa lijonge, iintsuku ezingama-15-21 ekuphuhliseni zibaluleke kakhulu. Eli nqanaba lidibaniswa nokubunjwa kwamatye e-nervous, circulatory, respiratory, excretory, digestive systems. Kulo mfa nekiso unokubona oko kubonakala ngathi umntwana ozayo. Iifom zeethala ezibanzi. Kule ndawo apho umntwana uza kuba nekhanda kamva. Usuku 21 luqala ukuphuhliswa kwengqondo kuphela.Kwinqaku! Kulo nqanaba lwenyanga yokuqala yokukhulelwa, intliziyo iqala ukubetha.
4 ngeveki kunye nesithombe kunye nencazelo
Kwiintsuku ezingama-22-28, njengoko kunokugwetywa kwi-photo kunye nevidyo, umntwana ubonakala ngokucacileyo kwi-ultrasound. Ixesha lidibene nokuqhubeka kwebhukimakhi kunye nophuhliso lwezitho. Kukho izikhokelo:- kukhanya;
- isibindi;
- izintso;
- umlenze.
