Amai vese vekuuya vanofarira kuti hupenyu hutsva hunokura sei mukati maro, uye uku kushandurwa kunotungamirira pakuumbwa kwevanhu vatsva. Kune nzira dzakawanda dzekuparadzanisa nguva yekudzivirira mune dzimwe nhanho, chimwe nechimwe chazvo mumakiriro ari kuvepo pane zvimwe zviitiko. Tichaedza kuratidza matanho ekufambisa kwe fetus panguva yekuzvitakura.
Ikutanga (kutanga) danho rekuzvitakura
Chikamu chekutanga chepamuviri chinotanga mazuva manomwe kusati kwasvika kwekuenda kumwedzi uye kunoguma mazuva manomwe pashure pokutanga kwekukurumidza. Munguva iyi, mukadzi angave akanzwa kusuruvara kwemafuro, kushungurudzika kunonzwisisika mumugwagwa, kufanana neinoitika musati wasvika kumwedzi, uye kuwedzera kwekushisa kwepasi kunopfuura 37 ° C. Vamwe vakadzi vanoona mavara mumazuva ekutanga ekufanirwa kuenda kumwedzi, iyo vakadzi tora kuenda kumwedzi kunopa ropa. Chiratidzo chinonyanya kuvimbika chekutanga chekutanga pakuberekwa ndechekuita mutsara unobata pamuviri . Asi zvakanakisisa kuitisa chirongwa chekuongorora ropa rekuraira kuti uone chorionic gonadotropin, inowedzera nokukurumidza pakuzvitakura.
Matanho ekudzivirira pamuviri nevhiki
- Purogiramu yekutanga yehutumbi, embryo masero anoparadzaniswa zvakasimba, akaiswa muuterine cavity uye chorionic villi inokura mumadziro ayo.
- Muvhiki yechipiri masero e morula anoenderera mberi kukura mumadziro emuviri, uye zvinonyanya kukosha - neural tube inotanga kuiswa.
- Muvhiki yechitatu, nhengo dzinotangira uye zvirongwa zvinotanga kuiswa: mwoyo, kupumha, kudya uye urinary.
- Vhiki yechina yakakosha nokuti embryo inotanga kuumba musana uye musimba, zvinyorwa-zvataurwa pamusoro apa zvinoramba zvichigadzirwa, uyewo mapango emaziso anoonekwa pahenya.
- Muvhiki yechishanu, mishonga yemwoyo, kudya, kudengenyeka, urinary uye kuporesa zvirongwa zvinoramba zvichikura, uye nhengo yekuona nekunzwa inotanga kuumba.
- Kubva pavhiki yechitanhatu kunotanga kuumba placenta, zvikamu zveuropi uye masimba emeso.
- Muvhiki rechinomwe-rechisere, chiso chemukati chinotarisa semunhu uye chave chiine maziso nemhino pairi, nzeve dzinoramba dzichikura.
- Phiki 9, skeleton inenge yakasikwa mumwana, uye anogona kutamisa minwe yake.
Nhanho dzekudzivirira pamuviri - kubva pamucheche kusvika kumucheche
Kutanga kubva muvhiki yechitanhatu yekutakura, embryo yakatoti yakanzi fetus, uye kubvira panguva iyo chigamba chitsva mukubudirira kwayo chinotanga - kukura nekugadzirisa unyanzvi.
Pavhiki 10 mucheche anenge atoziva zvakawanda - anowira, anopindira pahuma uye anofamba mudumbu, asi achiri muduku zvokuti amai havasi kunzwa izvi.
Mavhiki masvondo gumi nemasere ekuberekwa anokosha nokuti chibereko chinosvika kumucheto wepamusoro we pubic bone, uye mwana akatokwanisa kutarisana nechiedza uye ruzha, achiyamwisa munwe wake. Anozvibata zvikuru, asi amai vangu vachiri havanzwi.
Pamasvondo 13 kusvika ku14 zviratidzo zve toxicosis zvinopera, uye mumadzimai akawanda anotarisira mhumbu yatotanga kuonekwa. Munguva iyi, mwana anopiwa rudiments yemeno makumi maviri, nhengo dzomuviri dzinoumbwa, uye pancreas inotanga kuzadzisa basa rayo rekupedzisira (rinobudisa insulini).
15-16 mavhiki ndeye chiitiko chakakosha zvikuru, nokuti munguva iyi pasi inenge yakatangwa uye inoita basa rayo.
Pavhiki 17-20 yekutakura mukadzi anotanga kunzwa manzwiro ekutambudza mwana wake weramangwana. Munguva iyi, uropi nemanzwi zviri kukura.
Kubvira pamasvondo makumi maviri kusvika pakuzvarwa, pachavandudzwa nhengo uye zvirongwa zvinoitika, pamwe nekuwedzera kushingaira muhukuru hwe fetus.
Saka, taifunga nezvenzira yekutanga yekuzvitakura, iyo inonyanya kukosha, nokuti iri mumwedzi yekutanga iyo kuiswa nekugadzirwa kwenhengo uye zvirongwa zvinoitika. Zvakakoshawo kuti kubva muvhiki yechitanhatu yekutora musikana uyu watove watonzi fetus, uye kukura kwayo kunowedzera mukuvandudza nhengo dzatove dzakagadzirwa uye kuwedzera ukuru hwema fetus.
Vakadzi vane pamuviri vanorayirwa kuti vatore majekiti akawanda emiti. Asi zvinetso zvakadai zvinofanira kungova kuongororwa kwakagadziriswa kwepamusoro nekugadzirwa kwakanyatsorongeka, avo vanogadzirisa vari kuswedera nechisarudzo kusarudzwa kwezvinhu zvakagadziriswa, kutonga kwekugadzira uye kugadzirisa zvakasimba kunaka kwechigadzirwa. MuFinland, somuenzaniso, iyi ndiyo mavitamini ezuva ano "Minisan Multivitamin Mama", iyo zvino inowanikwa munyika yedu. Iyo mishonga inogona kutorwa sezvinenge iri kurongwa kwehupombwe, uye panguva yekuzvitakura uye lactation. Izvo zvakagadzirirwa zvakagadziridzwa zvichifunga nezvekuchinja kwemukadzikadzi panguva iyi. "Amai" vane zvinhu zvinokosha zvekuita pamuviri wakabudirira, kusanganisira folic acid, iron, iodine uye magnesium.
