Ikukurumidza kukura kwe fetus inenge ichizadza, vhiki yechitanhatu yekudzivirira ine zviitiko zvinokosha zvikuru munharaunda iyi, zvakare iyo inobata mwoyo, neural tube nezvimwe zvirongwa uye nhengo.
Zvakakosha kutaura kuti mwoyo muduku uri kurova, nenzira, nokukurumidza-2 kaviri kukurumidza kupfuura iyo yemwana wemwana. Apo ultrasound inopfuudza kazhinji kachenesa inokwanisa kubata maitiro aya. Ichokwadi, moyo hauna kukwanisa kuzadzika uye kupatsanurana kuve inrium kuchaitika muvhiki inotevera chete. Zvakanaka, nokuti ikozvino chirongwa chekubudisa masero eropa chinoita chiropa.
Vhiki yechitanhatu yekuzvitakura: fetal development.
Icho chiri pane izvi, vhiki yechitanhatu yekubata, iyo nzira yekuvhara zvakakwana kwe-neural tube (iyo ichasimbisa mhuka). Kuti udzivise zvinetso zvinogona kuitika, zvinokosha kuti urambe uchitora folic acid - izvi zvinonyanya kukosha! Kubva kune rumwe rutivi rwe-neural tube rakasimbiswa, uropi hunotanga kuumbwa: ikozvino panguva ino kuumbwa kwe convolutions uye kuora kunotanga, uropi hunove hwakafanana nehukuru! Mukuwedzera, kuumbwa kwedhehenya kunotanga. Chinofadza ndechokuti mwoyo nemisungo yemucheche iri kutoita basa, iyo inotungamirirwa neuropi.
Pane imwe nzira yekuparadzanisa masero emasero, saka unoda kuedza zvakanyanya, kuitira kuti hapana chinogona kuchinja kuumbwa kwenheyo yenheyo.
Muswe we embryo unova wakareba uye unopinda, kune zvimwewo zvimwe zvinoshanduka. Zvinokanganisawo 3 - seyamu hutachiona inokurumidza kukura. Kubva pairi inotanga kuumbwa kwemukumbo, chirwere chekudya, kupumha, kuchengetedza. Chikamu chayo chepamusoro chichava gorosi uye pharynx, anterior ichava sophagus, chikamu chepakati chinoumba hutema uye hutumbu mutsva, uye chikamu chekupedzisira - chirongwa chekunze. Pachave nekuparadzaniswa muzvikamu zve genitourinary system uye rectum. Zvinonakidza kuti panewo kupatsanurana kwepabonde, kunyanya, kuumbwa kwenyaya inotanga.
Pane kuenderera mberi kwekuisa nekugadzirwa kwemuviri wemuviri: mudumbu, chiropa, mapapu, pancreas. Ndiro vhiki ino iyo thymus (thymus gland) inoumbwa - nhengo inonyanya kukosha yehutachiona hwevanhu. Kana iri yekufema, inotanga basa rayo neyokutanga yekudzivirira mwana, apo pakarepo mushure mokuberekwa, kuzarura kwemapapu ake kuchaitika nekuzadzikisa iwo nemhepo.
Chirwere chechigamba chinoumbwa, izvi zvicharamba zvichiitwa mumwedzi wechipiri wekudzivirira. Iko kuumbwa kwemasumbu, tete, mapfupa. Pamasvondo matanhatu, kuumbwa kwegwenzi kunotanga.
Kuchinja kunoitika mu "chiso" chemukati. Izvo zvinyorwa zvemaziso zvakasimwa zvakasimwa, zviripo kumativi ose emusoro, zvinoswedera pedyo kune mumwe nemumwe. Panguva iyo ivo vakangoita huru kune dzimwe nhengo. Mukuwedzera, mhute, mhuno, muromo, nzeve dzinowedzera kuve dzakakurumbira, rudiments yemeno emazino akaumbwa.
Pamakumbo mava kutoonekwa mabhesi ekubatisa uye tsoka dzepamakumbo, pane zvigunwe zveminwe zviri pachena. Mukuwedzera, kune nzvimbo dzemabvi uye nehokwe mapepa.
Nokukurumidza zvakanyanya, iyo placenta inokura, inosvika 800 magamu pakuguma kwekuzvimba. Mukuwedzera, kune kuwedzera kwakanyanya kwenhamba ye amniotic fluid. Chinhu chinokambaira chiri nyore nyore uye chisingabatsiri mukati mavo nekubatsirwa kwembambo yembilical ine umbilical vein (kuburikidza naro, okisijeni uye zvose zvinovaka muviri zvinobva kumamai kusvika kumucheche) uye maviri embilical arteri, iyo inotora zvinhu zvose zvezvinhu zvinokosha mumutumbi waamai. Zvinonakidza kuti fetus iri kutotama-famba, asi amai vangu vachazvinzwa gare gare - chete pamasvondo gumi nemasere kusvika makumi maviri - iyi ndiyo yekuita pamuviri.
Izvo zvinoshamisa, zvichida, ndezvokuti chibereko chacho chichiri chiduku zvikuru: chinongova 4-9 mm kureba, asi chave chagadzirwa zvakanyanya!
Amai vangu vhiki masere vane pamuviri.
Amai vangu ikozvino vari kubhadhara mutengo wekushandura uku kukuru. Pakupera kwevhiki yechitanhatu kune kuwedzera kuwedzera kwekutanga kweaxicon. Nausea inogona kuva yakanyanya kukura, uye kunzwisisika kune zvinonhuwira zvinowedzera, salivation yakawanda, kuneta uye kusagadzikana zviri kuwedzerawo, kuwedzera kune engorgement yemakumbo emamota, kunzwa kunokonzera, uye inora yemukomana inosviba kunyange yakasviba. Zvose izvi zvinokonzerwa nebasa reHommonal, kunyange kune vakadzi vanogona kudarika nepanzvimbo iyi vasina humwe hurombo hwakanyanya uye husina kunaka.
Vhiki yechitanhatu yekuzvitakura: mazano.
Iko kunofanira kuyeukwa kuti yakaoma ikozvino yakanyatsokonzerwa nezvinhu zvinobva kunze. Iwe unofanirwa kuedza kusashandisa chero mishonga uye kupa zvinhu zvakanakisisa mamiriro:
• Kurega mamiriro ezvinhu anonetsa.
• Zorora nguva yakawanda.
• Kudya zvakakwana. Zvinokurudzirwa kutora chikamu chekudya, ndiko kuti, kudya kakawanda, asi mune zviduku zvishoma.
• Usarega kutora mavhithamini panguva yaunenge usina kurwara.
Saka mwana achagamuchira zvimwe zvimwe zvinodiwa. Unofanirwa kuedza kushandisa zvimwe zvekudya zvine calcium. Uye ikozvino panguva ino zvakakosha kusiya zvose zvidye zvinodyiwa.
• Zvakakosha kuyerwa nguva dzose, kana zvichidiwa - kuyera kushungurudzwa, panguva ino inogona kuwira pasi, asi kana ikawedzerwa, zvakakosha kuti uve wakangwarira. Zvinhu zvinoshungurudza zvinogona kuchinjawo kuwedzera kwekumanikidzwa, saka unoda kudzidza kudzikama uye kudzikama.
• Uye usakanganwa kushanyira kune gynecologist. Panguva ino iwe unoda kutora miedzo yeropa neropa, pavari chiremba achakwanisa kunzwisisa mamiriro emamiriro ekudzivirira.
