Mumazuva ekuita kwemavhiki manomwe , chimiro chiduku chine hurongwa hwekuvaka zvikuru. Iyo fetus inenge ichiine muswe, uye musoro uchiri mukuru kana uchienzaniswa nemuviri, asi maziso atova pedyo nebhiriji remhino uye maziso anotanga kuumba, iris inokura uye iyo pigment inowanikwa muziso retina.
Kuvandudza fetus mumavhiki manomwe ekuzvitakura
Iko embryo pachake yakanamiswa zvishoma - haisati yakangofanana neArc. Pamakumbo uye unobata iwe unogona kuona minwe, kune chigadziro chemapfudzi nemapuranga, chibereko chinoziva kukotamisa zvigadziri pamakumbo nemakumbo. Muromo wepamusoro uye mhino dzomutsipa zvinopesanidza zvakare, mukati nekunze nzeve dziri kuumba.
Kuvandudzwa kwenhengo dzomukati uye zvirongwa zvekare zviriwo zvakakwana. Semuenzaniso, mwoyo wemwana unotova nekodzero uye yakasara atrium uye muvhiki yechinomwe kune kugovana kwemoyo mumakamuri mana, saka inogadzirira "kutenderera" ropa riri kumativi ose emhuru. Mukuwedzera, kune hunobudirira hunobudirira mumutambo wevascular, kusanganisira kuumbwa kwemidziyo yakawanda yeropa. Nokukurumidza mwoyo uchange uine nzvimbo yawo, asi apo uri mukati memutsipa wechuru uye unofamba zvishoma mberi.
Pakave nekuparadzaniswa kweuropi mukati maviri hemispheres uye iye zvino madhipatimendi ayo mashanu anotanga kuumba. Nenzira yeutsi iri kuwedzera zvakare nekukurumidza zvakakwana, pane yose yakatove yakagadzirwa.
Asi ikozvino kukurumidza kukura kwe fetus. Kuumbwa kwefupa rinotanga uye kuumbwa kwepidermis. Usarega shure uye nhengo dzomukati: ramangwana bronchi rakaiswa, mapapu, utumbo, itsvo, mafungidziro endocrine anoenderera mberi kukura. Yakapedzisa kugadzirwa kwemukumbo mukuru, appendix, bile ducts muropa. Mune pancreas, kukura kwe insulin kunotanga.
Muvhiki ino yekubata, kuratidzwa kwepabonde kuchaguma kusvikira pakuguma: maitiro epabonde achagadzirwa mukati ma mavha mavari kana kuti mumatete, uye kubva pakuguma kwakagadziriswa muine perineum zvakare kunze kwenhengo dzebereki dzichaumbwa. Asi ultrasound haigoni kutsanangurira zvepabonde yemwana.
Mwana wacho atove akareba kwenguva refu, kana tichienzanisa nemavhiki ekutanga - KTP yake - huwandu hwekodhi-parietal inenge 13 mm. Asi kune hutano hwekuparara, naizvozvo amai vanofanira kuzvitarisira.
Uteroplacental exchange
Muvhiki ino, umbilical cord yekugadzira yakagadzirirwa zvachose uye shanduko yeterterclacental pakati peamai nemwana inotongwa. Mwana wacho anonyanya kuvimba newe, kufema nekuedza nemubatsiro wezvinhu zvinopinda muropa raamai - haufaniri kukanganwa nezvazvo. Iyo placenta inowedzera inopisa, kuitira kuti igare yakagadzirirwa nevhiki yegumi nembiri yekuzvitakura. Chibvumirano kubva pamaketeni ndiko kuchengetedzwa kwechecheche, hongu, kwete kubva "zvose zvinogumbura". Mukuwedzera, muvhiki yechinomwe, chironga chinoputika chinoumbwa kubva mucous uterine, iyo yakaumbwa. Ndiyo "gedhi" rinovhara kuwanikwa kubva munyika yekunze kunyika yenyika. Iyo ipulagi inenge ichingobuda kwenguva yakati isati yaboneka uye ichava chiratidzo chokutanga chekuzvarwa kunouya.
I-placenta iri mukugadzirirwa kwebasa rekubudisa mahomoni, ayo anoitwa kusvikira mucheche muviri. Kana ikaumbwa uye ichikura pasina zvipingamupinyi nekuputsa, zvino mumwe haafaniri kunetseka, asi pane imwe mamiriro ezvinhu, izvi zvinogona kuderedzwa, izvo zvinosanganisira kukanganisa hutoni hunokosha hunodiwa kuchengetedza mwana. Iboka rakanyanya kukanganisa rinosanganisira vakadzi vane chirwere chepachirwere munguva ino, vachangobva kubvisa pamuviri, vane hutachiona hwechibereko pamwe nevaya vakave vasina kukodzera kumwedzi uye zvirwere zvepabonde.
Kana iwe usati wakanyoresa, ino ndiyo nguva yakakodzera yeiyi. Iwe unofanirwa kupedza maedzo ose ekuongororwa kunodiwa, izvo zvinosanganisira kuongorora Rh-conflict. Iva nechokwadi chekuona chiremba kana iwe uine zvirwere zve endocrine.
Kuchinja mumukadzi mumavhiki manomwe ekuzvitakura
Muvhiki rechinomwe rokutakura, mazora ariola anotosviba, uye mutsara wemisi unogona kuonekwa pamimba. Mukadzi anogona kutanga kutambura mumucheche pasi uye kumativi pamusana pekukura kwechibereko.
Sezvo ruzivo rweropa ruchiwedzera, runogona kupera mumakumbo, zvichiguma nekudzimba, uye dzimwe nguva rinoratidzika kuti kune kushayikwa kwe okisijeni uye mukadzi ane pamuviri angakanganwa.
Zvose zviratidzo zvekuzvitakura, izvo zvinosanganisira kutanga toxicosis, zvinoratidzwa zvakajeka. Amai vemazuva ano vanogona kuwedzere kutsamwa, kurara, kuneta - vanoda kurara maawa 8-9 pazuva, nokuti muviri uri kushanda nesimba uye unoda kuzorora zvakanyanya. Usakanganwa nezvekushandiswa kwevhithamini uye kudya kunovaka muviri. Zviri nani kuti upe zvokudya zvakanaka, unofanirwa kudzivisa kusvuta, zvakabikwa, zvinonhuwira, zvokudya zvine salty. Zvishoma nezvishoma uremu hunotanga huchatanga, uye munguva pfupi pachava nemumbu. Asi haufaniri kurega mafuta nemakhahydrates (zvakasikwa, anobatsira): ivo vanopa simba uye simba kumwana nekuda kwekuvandudza kwake nekukura.
Mhedziso 7 vhiki: mazano kune vakadzi vane pamuviri
Sezvo zvichibvira zvinokurudzirwa kuti uende, famba mumhepo itsva, ita nguva yekuita gymnastics kuvakadzi vane pamuviri, zvakanaka, kubva pamitambo zvinodiwa kuramba.
