Muizvi 15th vhiki yekuzvitakura, i.e. 17 vhiki, "fetus" inosvika 16 cm, tsoka yaro 2 cm uye dehenya rayo 4 cm mudhayamita. Inorema 135 g.

The 15 vhiki fetus inofamba zvine simba. Aya mafambiro akakosha pakukura kwayo kwakakodzera: anobvumira kuti cartilage yemajoini akasiyana kupera uye kuve nechokwadi chekufamba-kwekuwedzera mafambiro ezvikamu zvakasiyana.

Manzwiro aro akasiyana anoramba achikura. Maziso anoramba akavharika asi pasi pemaziso ake pakaumbwa uye retina yake inonzwa kujeka. Parurimi rwake, tumabundu twekuravira.

À 17 mavhiki, itsvo dze "fetus" dzinoshanda uye dzinopinza weti muamniotic fluid.

Muchibereko, mwana haafeme nemapapu ake. Anodhonza oxygen yake kubva muropa raamai vake, kuburikidza ne placenta uye nerukuvhute. Mapapu ake anoramba achikura kusvika pakupera, asi atova nekunyepedzera-kufema mafambiro: chipfuva chinosimuka uye chinodonha. Panguva yekufamba uku, fetus inoshuva amniotic fluid uye inoiramba.

Iyi amniotic fluid, iyo chaiyo yemvura cocoon yemwana, inozadzisa mabasa akasiyana:

• basa remagetsi: rinotora kuvhunduka, rinodzivirira mwana kubva kune ruzha, rinoita kuti rirambe richipisa, rinodzivirira kudzvinyirira kwetambo. Inobvumirawo "fetus" kufamba zvakasununguka uye kukura bronchi yayo uye pulmonary alveoli kuburikidza nekunyepedzera-kufemerwa mafambiro;
• basa reantibacterial: sterile, iyo amniotic fluid inodzivirira fetus kubva kuhutachiona hunogona kusimuka kubva mumukadzi;
• basa rekudya kunovaka muviri: rinopa mvura nemamineral munyu kumwana ari mudumbu anoramba achitora mvura iyi kuburikidza nemuromo neganda.

Kutanga the Mwedzi wechi4 wepamuviri, iyo placenta inotora kubva ku corpus luteum uye inobudisa progesterone, hormone yekuchengetedza pamuviri, uye estrogen.

Nhumbu ine mwedzi mitatu, Mavhiki makumi matatu nepfumbamwe ane pamuviri, mwoyo negadziriro dzeropa zviri kutekeshera. Chiyero chemasero matsvuku eropa chinokwira nekukurumidza kuitira kuti aendese oxygen inodiwa kumwana. Pakupera kwemwedzi wechina wekuzvitakura, huwandu hweropa huchava 4% kupfuura kunze kwepamuviri. Kuyerera kweropa uku kunonyanya kuoneka pamwero wezvakasiyana-siyana mucous membranes. Saka, hazvishamisi kutambura kubva kakawanda nosebleeds panguva yekuzvitakura.

Pamasvondo e17 ekuzvitakura (masvondo gumi nemashanu), chifuva hachina kunyanya kunetseka asi chinoramba chichiwedzera huwandu nekuda kwekugadzirwa kwevascular network, acini (maduku maduku anobudisa mukaka) uye mukaka wemukaka. Mukati mechikamu chechipiri chetatu, mazamu anotanga kubudisa colostrum, uyu mukaka wakakora uye weyero wokutanga, wakapfuma zvikuru muzvokudya zvinovaka muviri, izvo mwana achangoberekwa anonwa pakuberekwa uye kusvikira kuyerera kwomukaka kwasvika. Pane dzimwe nguva kubuda kudiki kwecolostrum panguva yekuzvitakura.

Uku ndiko kutanga kwe 2nd kota uye amai vaneramangwana vakawanda vanogona kutanga kuona kufamba kwemwana wavo, kunyanya pakuzorora. Kana ari mwana wekutanga, kune rumwe rutivi, zvinotora imwe kana vhiki mbiri.

Pasi pesimba rekudyara kwehomoni uye shanduko yevascular, akasiyana dermatological kuratidzwa kunogona kuitika: nyowani nevi (moles) inogona kuoneka, superficial angiomas kana stellate angiomas.

Le Mwedzi wechi4 wepamuviri, amai vachazova vanofanira kuramba vachichengetedza muviri wavo kuti uwedzere mvura. Mvura inobvumira tsvina kuti icheneswe, kuburikidza neitsvo dzemukadzi ane pamuviri uye iyo ye15-vhiki ye fetus, iyo inoshanda panguva ino. Mvura inodzivirirawo kupera kwemvura uye kuneta panguva yekuzvitakura. Pakupedzisira, mvura inobatanidzwa mukutakurwa kwezvokudya mumasero emuviri. Kunwa 1,5 L yemvura zuva nezuva saka inokurudzirwa zvakasimba, kunyanya mukati memwedzi ye9 yekuzvitakura. Mukuwedzera kumvura, zvinokwanisika kunwa mishonga yemiti uye kofi, zvichida pasina caffeine. Muto wemichero kana wemuriwo uzerewo nemvura. Zviri nani kuti ivo, zviri nani, vakagadzirirwa kumba uye vasina shuga.

À 17 mavhiki e amenorrhea (15 SG), yasvika nguva yekuti amai vanenge vachizova vagadzirise madyiro avo kuti aenderane nemamiriro avo, kusvika pakusununguka. Pane zvishoma zvekudya zvekudzivisa panguva yose yekuzvitakura, zvakadai se: 

• nyama nehove mbishi, kusvuta kana marinated;

Kune rumwe rutivi, kudzivirira kukanganisa kunogona kuitika kwe fetal, kushandiswa kwezvimwe zvekudya kunofanira kuderedzwa, zvakadai se soy, sweeteners kana hove huru. 

Mamwe maitiro anogona kutorwa sekugeza maoko zvakakwana usati wabata nyama mbishi kana miriwo nemichero yakasvibiswa nevhu, kudya nyama yakabikwa zvakanaka, hove nemazai, uye pasteurized mukaka chizi.

• kukumbira kadhi renyika rekutanga kubva kuFamily Allowance Fund. Iri kadhi rinopihwa mahara pakukumbira kune CAF yedhipatimendi rayo, neemail kana kutumira. Nekuda kwezvinyorwa R215-3 kusvika kuR215-6 yeKodhi yezvekugarisana uye mhuri, inopa panguva yese yenhumbu kodzero yekukosheswa yekuwana mahofisi nemakaunda ehutungamiriri nemabasa eruzhinji uye kune zvifambiso zvevoruzhinji.
• ita nguva yekushanya kwemwedzi wechishanu, yechi5 yenguva 3 dzekumanikidzirwa kushanya kwevasati vasununguka.

Ce 2nd kota Kubata pamuviri ndiko kunowanzoita kuti amai vanozova vanenge vasina kuneta. Ngwarira, zvisinei: iwe uchiri kufanira kungwarira. Kana kuneta kana kurwadziwa kuchinzwika, kuzorora kunokosha. Kana pane nguva yaunofanira kuteerera "intuition" yako uye ugare wakatarisa kumuviri wako, imimba.

Hatisati taziva mhedzisiro yemamwe makemikoro emakemikari, uye kunyanya ayo eVOCs (volatile organic compounds) pakukura kwe "fetus". Nekuda kweiyo precautionary musimboti, saka zviri nani kudzivirira kuratidzwa kune izvi zvigadzirwa zvakanyanya sezvinobvira. Iyi mwedzi mipfumbamwe mukana wekutora mararamiro ane hutano nekusarudza chikafu chekudya (kunyanya michero nemiriwo), zvakasikwa kana organic runako zvigadzirwa. Mazhinji emhando yekuchenesa dzimba zvigadzirwa zvakare hazvikurudzirwe panguva yekuzvitakura. Vanogona kutsiviwa neavo ecological yakaenzana kana nezvigadzirwa zvechisikigo - chena vhiniga, sipo nhema, kubika soda, Marseille sipo - mumabikirwo emumba. Muchiitiko chebasa mumba, sarudza zvigadzirwa zvinoburitsa zvishoma VOCs (kirasi A +). Kunyange nechenjedzo iyi, zvisinei, amai vanozova amai havakurudzirwi kutora rutivi mubasa racho. Isu tichavawo nechokwadi chekuti imba yacho ine mhepo yakanaka.
