Pamasvondo gumi nemana, nguva yekubryonic yekukura kwema intrauterine inoguma uye nguva yekutora inotanga, apo mwana wako atova kunzi fetus. Kubvira panguva ino fetus inotanga kukura nekushingaira, uye pamwe nayo iyo mimba yaamai inokura zvakare.
Uye kunyange mumasvondo gumi nemana ekuberekwa ukuru hwemuviri wemukadzi ichiri chiduku zvikuru, uye dzimwe nguva ichiripo, kuwedzera kwacho kunotanga. Pakati pese, kukura kwemuviri wepamuviri panguva yekuzvitakura kune pfungwa yakasiyana. Zvakawanda zvinoenderana nemufananidzo wemudzimai, pane zvaanotomical. Vakadzi vadzimai vane mapapiro maduku vasati vaona kuonekwa kwemuviri uye zvakasiyana.
Mukuwedzera, dumbu rinokura pamwe chete nehuwandu hwekuwedzera, saka paunenge uine pamuviri, unofanira kutarisa uremu hwako uye urege kuwana zvakanyanya. Chikonzero chikuru icho chiremba anofungidzira kufambiswa kwemwana ndiko kukwirira kwechibereko panguva yekuzvitakura . Ichi chiratidzo chinofananidza nguva yekudzivirira.
Nei dumbu richikura?
Zvingaita sokuti mhinduro yacho iri pachena - mwana anokura mairi. Asi chaizvoizvo, zvinhu zvose zvakaoma zvikuru. Mimba panguva yekuzvitakura inowedzera nekuda kwekukura kwechechi kwete chete, asiwo chibereko, uyewo kuwedzera kwehuwandu hweamniotic fluid.
Urefu hwe fetus hunotsanangurwa ne ultrasound. Pamasvondo gumi nemasere ekuberekwa, mwana (fetus) ane uwandu hunenge 6-7 cm, uye uremu hwahwo hunenge 20-25 g. Panguva imwechete, ultrasound inoratidza kuti fetus inenge inenge yakabata zvachose uterine cavity.
Pachiedza chekusimba, iwe unogona kuona kuti chibereko chinotarisa sei mumavhiki gumi nemana. Zvinonzwisisika kuti musoro wake hauna kunyanya kukoshesa pakuenzanisa nedu uye unotora hafu yakanaka yehuwandu hwema fetus. Munguva iyi, uropi hwake hunotanga kushingaira.

Inowedzera panguva yekuzvitakura uye chibereko. Kana usati wava nepamuviri inorema inenge 50 g, zvino pakuguma kwekuita pamuviri, kuyerwa kwayo kunokwira kusvika ku 1000 g, uye chikwata chacho chichawedzera 500 kana kupfuura.
Kukura kwechibereko mumavhiki gumi nemaviri kunopfuura katatu kupfuura usati wava nepamuviri, uye ikozvino kune chimiro chakakomberedza. Ichi chimiro chichachengetedza kusvika kusvika chetatu chetatu, uye ichava ovoid.
