38 vhiki yekutakura amai nemwana

Panguva iyi, chibereko chacho chinowanzosvika 2800 - 3200 gm uye kuwedzera kwe 48-52 cm.Zvose nhengo dzaro uye zvirongwa zvatove zvagadzirirwa hupenyu kunze kwemuviri wemamai. Hapana majeko ekufambisa, mabasa ese anoshanda zvakanaka uye zvishoma nezvishoma anovandudzwa.

Vhiki yepfumbamwe yehutatu ndeye nguva yekupedzisira yekuumbwa kwemapuraneti. Chigadziko chealveoli chinopedzwa nekukapfekedza nechinhu chakakosha - unofambisa mafuta, izvo zvinodzivirira kuti alveoli igare pamwe chete. Nzvimbo inokosha inoumbwa muuropi, inotarisirwa kufema. Zvose izvi zvichazopa mwana mukana wekutanga kufema.

Chiropa uye pancreas zvinoramba zvichikudziridza, yevhiki 38 yekutakura haisi yekupedzisira, nokuti inoshanda zvakakwana zvizere mushure mokunge mwana aberekwa.

Itsvo uye uropi zvishoma nezvishoma zvinoramba zvichikura. Iye zvino mwana wacho anonyanya kunetseka nemanzwiro amai vacho.

Inotanga kusundira uye kuchinja zvishoma. Nzvimbo yacho haina kukwana kwaari iye zvino, musoro wakakoromoka, asi kushamwaridzana kwake kwakanyanya kumeso amai havasi kungonzwa chete, asi vanocherechedza nenzira yekutama tubercles padumbu: bhokwe rinodzima kunze, asi chitsitsinho chinofamba.

Uyezve, kutanga pavhiki 28, meconium inounganidza mumuviri wemwana - iyo inosanganiswa yemafuta akafa akafa, ayo akazodzika pamwe neamniotic fluid. Kazhinji meconium inotanga kubva mumatumbo mumaawa ekutanga mushure mokuberekwa.

Kwaamai

Apo paine masvondo makumi matatu nemasere ekuberekwa, zvino muzamu huve hukuru kwazvo, kubva mukaka hunoita dzimwe nguva huchidonha. Yenguva yekutanga kusunga bhandi rakasimba rakaitwa neshinda yepanyama nemapadhesi anokwanisa kubviswa, izvo zvichabatsira zvakawanda pashure pokunge aberekwa, munguva yose yekuyamwisa.

Kuremera kwaamai kunorega kukura, uye kunotanga kuderera. Mumavhiki mashomanana ekupedzisira ekudzivirira, kikigiramu inowanzosara - imwe nehafu.
Vazhinji vanaamai vaduku vanotya kusaona panguva iyo kuberekwa kwakatanga, saka vachadzidza zvakanyanyisa pamusoro pezvipi zviratidzo uye zviratidzo zvekutanga zvekuti kuberekwa kwave kuswedera pedyo.

Nenzira yakawanda, chimiro chemagetsi ekutanga kwebasa rekushanda kwebasa rakapa zvakakwana: kubva masvondo makumi matatu iyo placenta inotanga kufamba "shoma" zvishoma nezvishoma, inoderedza simba rayo rehomoni. Somugumisiro, mwana wacho anonzwa kuperevedza kwezvikamu zvakakwana zvekufema kwakakwana uye kudya kunovaka muviri, kunosimbiswa nekuda kweizvi. Muropa raamai, "hormone inomanikidzika" yemwana-cortisol, iyo inopa muviri kuti unzwisise kuti inguva yekutanga kubereka. Uterus, mushure mekugamuchira chiratidzo kubva muuropi, inotanga kuderedza zvakasimba - kurwa kunotanga.

Kuberekwa kwekutanga kunonyanya kushanya, nekupedzisira, sekutonga, maawa 12-18. Nokudaro, iwe uchava nenguva yekuenda kuchipatara nenguva, usamhanyira ipapo nechitarisiko chekurwa kwekutanga, kana pasina chimwe chinokutambudza, hapasisina kubuda ropa, uye kushambadzira kwe fetal hakusi kuderedza.

Kuuya nokukurumidza

Vhiki yepfumbamwe yehutatu inowanzoperekedzwa nezviratidzo zvekuti kuberekwa kwaswedera.
Chimwe chezviratidzo izvi zvinoshamisa uye zvinokurudzira izvo Amai vanonzwa zuva rimwe kana maviri asati aberekwa. Kuneta kunotsiviwa nekushingaira uye chido chekuita zvinhu zvose panguva imwechete, kuronga kushandiswa kwekugarisa, kurongedzazve - chero "revolution" mumba.

Kana mavhiki makumi matatu nemasere ekuberekwa asvika, inodhonza dumbu uye nzvimbo ye sacrum, inopindira mumapapiro uye rectum, ipapo musoro wemwana wakatowedzera mberi kusvikira kumuromo wechivi, mapfupa emapilvic anotanga kuparadzaniswa, mvura inoberekwa inogadzirira mwana.

Kusununguka kubva mumudzimai kunogona kuwedzera, mucous stopper ichabva kana amniotic fluid ichadonha, zvose zviratidzo zvekutanga kwebasa. Uye kana pane zviyero zvemuvara wepiniki , ipapo kuberekwa kunogona kutanga chaiyo mumaawa makumi mana anotevera. Uyu ruvara rwekuyerera anoratidza kuti pane kuvhura zvishoma nezvishoma kwechirwere, iyo inoperekedzwa nekupararira kwemidziyo midzi yeropa.

Kunyangwe usati waberekwa, muviri unoedza kucheneswa mumarudzi ose, saka kushushikana pamushure wekupedzisira kwemavhiki makumi matatu nemasere ekuberekwa, kurutsira, chirwere chepachiviri, kushungurudzika mudumbu, fivha (pamwe chete kuti iwe haungagoni kuisa chepfu chero chinhu) zvinoreva kuti iwe uchaona mwana achangobva kusvika.
