Mumavhiki mashomanana ekutanga ekudzivirira, jaya rechidiki rinowanzoti chorion, iyo inokosha pakuzadzikisa kwemuwana. Kazhinji, iyo placenta inonamatira pasi pechibereko kana mushure kumashure. Asi dzimwe nguva chorion inogadzirisa pharynx zvachose kana zvishoma, kugadzika pasi muzasi. Muchiitiko ichi, taura nezvekuratidzwa kwechirion .
Ngozi yehurukuro yehurukuro
Mharidzo ye chorion inotsanangurwa pavhiki 12 panguva yekutanga yakagadzirirwa ultrasound. Zvinokwanisika kuona hutachiona pane imwe nguva yapfuura kana ultrasound ichiitwa kwechimwe chikonzero kusvika kumavhiki gumi nemaviri. Nezvo kuongororwa, mukadzi anogoverwa kurara pamubhedha, kazhinji inoda kugara muchipatara kuti itarisire pamuviri. Mukukura kwemuviri uye chibereko, placenta inowanzokwira kumusoro, inonzi inofanirwa kukurudzirwa kwezviitiko. Izvi zvinonzi "kutama kwepa placenta". Somuenzaniso: mharidzo ye chorion pavhiki vhiki 15 inogona kupera zvachose nemavhiki 20-25. Chinhu chipi nechipi chekubatanidza chorion ndeyechimiro chechimiro, apo mwana ari pane imwe nzvimbo yemamita 3 cm pamusoro pekunze kweprynx.
Kuparadzanisa kwepakati pepakati kunowedzera dambudziko rekubuda ropa uye kupererwa kwepamusoro. Asi kunyange munyaya iyi, mushure mekubvunzisisa kwakanaka, mukadzi anocherechedzwa pasina. Kana chorion ichive yakaderera zvikuru zvokuti inodzima zvachose pharynx, ipapo pakutanga kwetatu mamiriyoni ekudzivirira, kunyange kana iwe uchinzwa zvakakwana, iwe unofanira kuenda kuchipatara. Izvi zvinobatanidza nehuwandu hwehuwandu hwekuvandudza kukanganisa kwakakonzera kupera uye kubuda ropa kwakanyanya kunopisa hupenyu hwemukadzi. Kana hutachiona hunoonekwa, kuwanda kwechirion kunotarisirwa pamasvondo gumi nemaviri uyezve, izvo mumutambo wekutanga kunofanira kuenzana (mum mm) nguva yekuita (mumavhiki). Kana mharidzo ichichengeterwa kusvikira kuberekwa, mwana anoonekwa muchiedza nechikamu chekudzivirira,
Zvinokonzera
Iyo mharidzo ye chorion pavhiki 11 inowanzowanzokonzerwa nekuputika kukuru, iyo inowanzobatanidzwa nematambudziko pashure pokubvisa pamuviri . Uterine mishonga yakakanganiswa, zvichibva pamusana pekuti egg haigoni kuzvibatanidza mune imwe nzvimbo yepanyama iyo (anterior kana kumashure masvingo emuviri). Mukuwedzera, mharidzo ye chorion yemavhiki gumi nemaviri inogona kuitika nekuda kwemajamu akawanda kana mapuropiti emuviri. Saka, pakuronga kubata pamuviri, zvinokurudzirwa kuti zvipembenene zvose zviripo zvabviswa.
