Mwedzi wechinomwe wekudzivirira uri kuuya kumagumo: kubva mavhiki makumi maviri nemaviri anotanga wechitatu - yechitatu yekupedzisira yekuzvitakura . Zvose nhengo dzomwana dzave dzatangwa, asi ramba dzichikura nekugadzirira hupenyu kunze kwemuviri wemubereki. Uropi hunoenderera mberi kukura.
Chiremera chemucheche pamasvondo makumi maviri nemaviri chinenge kikilogram: inogona kubva 900 g kusvika 1300 g (mavheji). Kukura kwema fetus pamavhiki makumi maviri nemaviri (fetometry ye fetus isvondo makumi maviri nemaviri) inogona kuchinja zvichienderana nekukura kwezvinhu zvechecheche. Pamasvondo makumi maviri nemakumi maviri ekuberekwa, fetal inoshandiswa ne ultrasound test (fetus uzi masvondo makumi maviri nemaviri) - 34-37 cm, kubva korona kusvika kumuswe 24-26 cm.
Kukura kwemasvondo emusoro wemusoro, iyo ichapa pfungwa yekuti mwana anotarisa sei, ndeyotevera:
- biparietal size (bppr 27 vhiki) i 69 (mm);
- chimiro chedehenya ndewe 215 (mm);
- nharaunda yehenya iri 3675 (mm).
Inenge kusvika kumavhiki makumi maviri nemaviri ekuberekwa, retina yakaumbwa zvakakwana, maofidi akazaruka uye eyelashes kukura. Basa raidiwa pamucheche ndevhiki makumi maviri nemakumi manomwe nemakumi maviri nemana - kuyamwa munwe, iyo inoramba ichidiwa pashure pokunge aberekwa.
Mapapu emucheche anoenderera mberi kukura. Kufema kwekufukidzira kunopiwa ne-placenta, iyo mairire embilical anoshandura gesi pakati peropa remu fetus uye ropa raamai. Kufuridzirwa kwemapfupa emucheche anobatsira mukurudzirwa kwemapfupa ekufema, kukura kwemapapu uye kupararira kweropa ye fetus, kuwedzera kubuda kweropa kumwoyo mushure mekunge kusati kwamanikidzwa mubhokisi re fetus.

Vakasvuta vanofanira kusiya kusvuta, uye vasiri vasvuta havasi munzvimbo dzinozara-futi, sezvo mwana ari kutambura nekusvuta utsi hwefodya.
Vakadzi vazhinji, zvikuru avo avo vane hanya zvikuru nehuwandu hwavo, vanovhiringidzika zvikuru nekuwedzera kwehuwandu uye kuyerwa, izvo zviri pachena mumatatu matatu. Vanaamai vakawanda vanotarisira vane dambudziko nemapfeko, havakwanisi kukwira ku jean dzavo dzinodiwa uye vanoda kutora mabheji chaiwo uye jeans kune vakadzi vane pamuviri vane bhanhire rakasununguka pachiuno kuti varege kumanikidzira mwana. Mitsipa inokura, iwe unofanirwa kupfeka shangu zvigadzikane chete, pasina chitsitsinho, dambudziko iri rinonyanya kuoma munguva yechando. Pasinei nekushanda kwakakosha, kudya hakugoni kuteverwa uye iwe unogona kuzvidzora mune zvekudya, unoda kuderedza kushandiswa kwemakhahydrates, uye kudya kunofanira kuva kwakanaka uye nguva dzose. Nekutaridzika kwechimiro chechecheche, chifuva chemazuva amangwana amai chinoshanduka, chinowedzera
Zvibereko mumavhiki makumi maviri nemaviri
Iyo fetus iri pamavhiki makumi maviri nemaviri inotaridzika sechechechecheche, muviri wake wakaenzana, chiso chave chakaumbwa uye iye, anonzwisisa apo chiedza-chinozarura meso ake uye chinotendeukira musoro wake. Mwana wacho anoramba achitendeuka, pasinei nokuwedzera kwomuviri uye urefu. Kupera kunenge kwema 140 kurova paminiti, kupumha kunenge makumi mana neminiti. Vanachiremba vanotaura kuti kana vakaberekwa pakutanga, fetus inopona mumasvondo 27-28 muna 85% ematambudziko, kazhinji kukura uye kubata mukukura nekukura-kurema kwevezera ravo.
