I-fetus iyakhelwe ngokupheleleyo kwiveki yama-30 yokukhulelwa, iistim ze-cardiovascular and urinary systems sele zisebenza. Iimpawu kunye neengalo kunye nemilenze kubonisa indlela eqhutywe ngayo i-musculoskelet system, kwaye iimpendulo zeemoto ekuphenduleni kwisicatshulwa esicacileyo kunye nesibonakaliso sibonisa ukuphuculwa kwezitho zengqondo. Kwinqaku lethu, siya kuqwalasela iimpawu zokuphuhliswa komntwana kwisonto lama-30 lokukhulelwa kunye nobukhulu bayo.
Ubungakanani be-Fetal kwiiveki ezingama-30 zesisu
I-Fetometry ye-fetus yeeveki ezingama-30 zokukhulelwa iyenzeka ngexesha le-ultrasound. I-ultrasound ye-fetus yenziwa kwiiveki ezingama-30 ukuba kukho izibonakaliso (ukuhlola i-ultrasound kuqhutywa kwiiveki ezingama-32-34). Kwiiveki ezingama-30 zesisu, ubukhulu be-fetal buyi-38 cm. Ubunzima bomntwana obusweni kwiiveki ezingama-30 bu malunga nama-1400 amagremu. UKokchikotemennoy ubukhulu bomntwana kwiiveki ezingama-30 zesigxina se-27 cm.
Yintoni i-fetus kwiiveki ezingama-30 zokukhulelwa?
Kwiiveki ezingama-30 zokukhulelwa umntwana sele sele efana nomntu omncinci, unesilinganiselo esifanayo nomntwana osanda kuzalwa. Kule gama yokunyanyiswa komntwana umntwana ukhula kwaye uzuza. Ngalesi siko umntwana usoloko uyazi kakhulu. Ngokomzekelo, umntwana angakwazi ukukhanyisa ekukhanyeni okukhulu, usebenza ngakumbi kwi-stimuli ephilileyo. Ukungena kwe-amniotic fluid kungaphatshwa yintambo, leyo intokazi evakalelwa ngayo njengesigqi, kungekhona ukutshitshiswa okukhulu. Iintsana kule minyaka yenza ukunyakaza okuphefumulayo ukuya kwi-40 ngomzuzu, obangela ukuba kuphuhliswe imisipha ye-intercostal kunye nokuvuthwa kweethambo zamaphaphu. Kule minyaka, umntwana usenesikhumba esinyanisiweyo, eneenwele entloko kunye neenonkhoni zomzimba emzimbeni (iwegogo), ngokunyusa ukwanda kwamanqatha angaphantsi.
Imiva yowesifazane kwiiveki ezingama-30
Iiveki ezingama-30 zokukhulelwa lixesha lokuhamba kukaMama kwikhefu lokubeletha. Ubungakanani besisu ngesonto lama-30 lokukhulelwa landa kakhulu, i-center of gravity iya phambili kwaye ibhinqa kufuneka ilandele i-posture. Ibhinqa livakalelwa ukuba i-fetus ivuselela, itoni ye-uterine inokunyuka ngenxa yokwelula ngokukhawuleza kweendonga zayo. Ngelo xesha, ibhinqa linokuxhalaba ngokucoca rhoqo (i-uterus eyandisiweyo ixininisa i-vestile), ukukhupha okugqithisileyo (ukunyuka kwezinga lokunciphisa umzimba).
Ngaloo ndlela, sibona ukuba i-parameters ye-fetus kwiveki yama-30 yokukhulelwa ingaqwalaselwa yi-ultrasound. Umntwana omncinci kwiveki yama-30 ubonisa ukulibaziseka ekuphuculweni kwe-intrauterine, kwaye unokuthi ufumane ukungafezeki komntwana ( fetal hypoxia ) okanye ukusuleleka kwe-intrauterine.
