Isisu seveki le-16 lokukhulelwa sinokunyuka kwama-10-13 cm. Ubunzima bomntwana buvela kwi-55 ukuya kwi-100 g. Ngelo xesha, lo mfazi uzuza isisindo, ukuxhaswa okuqhelekileyo kuthathwa njenge-2-2.3 kg. Ubume be-uterus buyatshintsha, buba yi-hemispherical, kwaye ubukhulu bayo iiveki ezili-16 - kunye ne-melon encinci.
Iiveki ezili-16 - umntwana
Umntwana uqhubeka ekhula ngamandla, kwi-ultrasound i-KTR yayo (ubukhulu be-coccyx-parietal) kwiiveki ezingama-16 malunga ne-41 mm. Kwiiveki ezingama-16, kwaye uzimisele ubungakanani bomntwana njengengqungquthela ye-BPR (ubungakanani biparietal), ngowama-31-37 mm. Olu bukhulu lithetha ubungakanani obujikelezayo bentloko yesana.
Ukongezelela, kwiiveki ezili-16 zokukhulelwa, ubungakanani bomntwana obuthathatyathwa bunqunywe njenge-circumference yentloko yayo, enokulinganisa i-124 mm, umgama wesisu esiswini, ubude be-20 mm, ubude be-humer 18 mm, nobude be-forearm 15 mm nobude shin - 18 mm.
Ukongeza kwimilinganiselo, i-ultrasound ihlola izinto ezifana nokulinganisa kwamalungu, ukubonakala kwamathambo amathambo, okufuneka ukuba kubekho kunye neendlela ezingaphazamiseki. Ngeli xesha, sele sele kunokwenzeka ukucacisa ngesondo somntwana ozayo - izitho zangasese zenziwa kwaye zibonakala ngokucacileyo. Kakade ke, awukwazi ukukhuphela ukungalunganga kwinkqubo yokumisela, ngoko ungalindelekanga ukuba ulindele umntwana wesini esithile, ukuze ungakhathazeki xa kwenzeka impazamo.
Umntwana ubonakala njani kwiiveki ezili-16?
Umzimba wayo usenakuxhomekeka. Kuthetha ukuba intloko ihlala inxalenye ebalulekileyo yobukhulu bembungu. Sekunjalo neenwele zokuqala, ngelixa ziphelile, kodwa ngokukhawuleza xa isikhumba siqala ukuvelisa i-pigment, baya kuguqulwa kumbala wendalo. I-Marigolds ibonakala kwiminwe, imilenze iyaqhubeka.
Izibambo zizama ukufikelela kwaye zithatha imilenze, intambo yomlomo, iwafake. Kodwa ukwesaba ukuba uya kumgungqa kwaye azithintele ukungena kwi-oksijeni kunye nezondlo akudingekile - iimvini zezilwanyana ezikhuselekileyo zikhuselekile ngegobolthi ekhethekileyo kwaye azikwazi ukucwina iintsana zabo.
I-embryo kwiiveki ezili-16 iyaqhubeka nokuphuhlisa. Qalisa umsebenzi weentso kunye nesibindi, izikhukuphuku kunye nezigulane ezizimeleyo, ulungelelaniso lwezinto ezihambayo landa.
Iiveki ezili-16 - inzwa yowesifazane
Ngexesha leeveki ezili-16 zokukhulelwa, umfazi usenokuva uhambo oluthile lomntwana. Basoloko bebuthathaka kwaye banokudideka ngamathumbu emathunjini. Kunzima kakhulu ukuqonda umfazi ozalela okokuqala. Abafazi abanamava abasebenzayo banokuqonda ukuba le ntshukumo yomntwana wabo.
Ubungakanani besisu esisecaleni le-16 lisekuncinci, ngakumbi ukuba le ntokazi inomzimba omkhulu. Kule meko, ukukhulelwa kungahlala kungabonakali. Abasetyhini abancinci banamaqabunga amancinci banokuguquka okukhulu kakhulu - i-tummy yabo iqala ukubonakala ngokukhawuleza phambili.
Ngokubhekiselele kwiimvakalelo eziqhelekileyo - i-trimester yesibili, oyifakayo kwiiveki le-13, ichongiwe ngokufanelekileyo ixesha elihle kakhulu lokukhulelwa. Zigweba ngokwakho - awuyikukhathazeka yi-toxemia kusasa, imeko imele iphuculwe, ama-hormone ayenzi kakubi kakhulu, awufuni ukukhala nokuhleka ngexesha elifanayo. Kananjalo, isisu sisesekuncinci kwaye inzuzo yesisindo ayibalulekanga - ngoko kusekho lula kwaye kuyamnandi ukuhamba. Ngeli xesha, i-edema ne-varicose ayifumanekanga.
Umntwana sele sele uva izandi ngaphandle komama, ngoko kuyakunceda ukuphulaphula umculo womculo kunye nomntwana, uthetha naye, ucule iingoma kuye. Ukuphuhliswa kwengqondo kunye nengqondo yomntwana kuqala kwisibeleko . Makhe akhulume naye - umntwana uya kusetshenziselwa ilizwi lakhe nangaphambi kokuzalwa kwakhe.
Iyaqhubeka ukukhula kungekuphela nje kwesibeleko, kodwa kunye nesifuba, sinokubonakala kumatha amanetha kunye namanqaku atyulayo. Ukuze ugweme amanqaku eselula kungekhona kuphela esifubeni, kodwa nakwisisu nangomlenze, kufuneka usebenzise iindlela ezikhethekileyo kwaye ubukele ubunzima ngaphandle kokongeza kakhulu kwaye ngokuphawulekayo.
