8 Emasontweni onke okukhulelwa. wokukhula kwengane esiswini

Fetus uma sebehlanganisa amasonto angu-8 sokukhulelwa ifinyelela 14-20 mm ubukhulu. Ingane isivele ine zonke izinhlelo kanye nezinhlaka, baye cishe kuphelile ukwakhiwa yabo yokugcina. Izinyanga ezisele ngaphambi kokuzalwa umphakeli kuphela izakhi ne-oxygen ukuze umzanyana, kule nkathi uyaqhubeka ngcono yayo.

Nakuba isikhumba sengane cishe esobala manje namanje, izintende abonakala kakade umjuluko nezindlala, iziphi namanje kodwa angasebenzi. Kumaviki awu 8 yokukhulelwa ubuso imvuthu ke cishe kwakhiwa. Amehlo kabanzi sigudluke, kodwa athuthukile nezinzwa optic, i-retina kwakhiwa, crystalline lens futhi cornea. Iphela lapho kumiswa Isivalo, emhlathini kanye nengane attain ifomu evamile. Emlonyeni, kukhona ulimi esiye evuthiwe ukunambitheka efihlekile. Ajwayelekile kithi uhlobo uthola ekhaleni e ingaphakathi salo msebenzi onzima imfundo ama nezinzwa olfactory. Kodwa nakhu okuhlangenwe nakho iphunga ingane can okwamanje, ngoba amavesi acinene embozwe ngokuphelele Imigudu lwamafinyila. Futhi, kwakheka indlebe obungaphandle kule eside.

Found ithambo ezandleni nasezinyaweni, iza esiteji nokuvuthwa we uqwanga, ezoqhubeka emva kokuzalwa. Iqala kumiswa emalungeni. Kumaviki awu 8 yokukhulelwa ultrasound kuyabonakala ukunyakaza kwengane, futhi lokhu akumangalisi, ngoba ngaleso sikhathi imisipha kakade athuthukiswe kahle. Shaped ukuhlafuna imisipha. I izibambo insaliwe emalungeni ingane, futhi ezandleni kakade athuthukile iminwe. Ukuze kwesibeletho kuthatha isikhala okuncane, izinyane kuthatha okubizwa ngokuthi isikhundla fetus, okuyinto walondoloza phakathi nokukhulelwa. Ingane ngazo isibambo esifubeni, imilenze ibheke at inyonga nedolo amalunga omzimba. Uma elingenhla emikhawulweni iminwe phakathi ukwahlukanisa yacekeleka phansi ngokuphelele, ezansi, baba namanje ukugcina. , Kwamiswa Lokhu kungenxa yokuthi imilenze kuthiwa emuva ezandleni khona namanje, amalunga izinyawo, ngakho iminwe tho.

Eemvekeni ezi-8 ekhulelwe, umntwana inhliziyo 4-chamber, fetus ukugeleza kwegazi endleleni futhi imbobo phakathi Atria iqhubeka. It kuyodingeka izinyane inqobo nje ngeke bakwazi ukwenza umoya ezimele wokuqala, lokhu kungenxa yokuthi naphakathi-lesizalo kwegazi fetus kwenzeka hhayi njengendlela kuzalwa, umzimba omkhulu placenta kunokuba emaphashini.
Amathumbu yinde, ukwakha sebuningini izihibe nokwenza esiswini azungeza axis awo, le nqubo kuba isikhala kancane, futhi kancane wadalula e umzanyana (hernia embryonal). Ngenxa inqubo izitho zomzimba futhi kuyinto evamile, ukuze mayelana 11 Emasontweni onke okukhulelwa, amathumbu ubuyele ngaphakathi komgodi ongaphakathi kwamathumbu.

Eemvekeni ezi-8 ekhulelwe, ukwakheka kwe-fetus phansi. Ngo amantombazane, ezikhiqiza amaqanda kwenzeka ithebhu, abafana amasende. Esikhathini ingane owesifazane kule nkathi kuholela esizukulwaneni amaqanda, okuthi uma esikhathini esizayo uzobe esichithwa semfundo eqhubekayo. Ngamanye amazwi - amasonto 8 yokukhulelwa wabeka abazukulu impilo.

tubercle zangasese, liyala kokubili abafana namantombazane ngokufanayo, ibukeka nse, ukuze ukuhlonza wobulili wengane akunakwenzeka okwamanje.

Kwabesifazane abakhulelwe emavikini 8 kukhona ingozi kwesisu, ngokuvamile isisu nokuguqulwa kwenzeka ngokunembile ngalesikhathi. Brown noma ukubeka amabala, futhi ubuhlungu emizweni ukuthi ukudansela isiginci sakhe esiswini ephansi emuva, kuqubuka kungenzeka enkingeni. Ngakho-ke, lapho izimpawu ezifanayo zidinga esibhedlela ngokushesha. Kufanele kube isaziso ushintsho olunjalo emzimbeni futhi kudingeka ngokushesha uxhumane udokotela.
