Amniotic fluid

Amniotic fluid yakajeka, zvishoma yero mvura inokomberedza mwana asati azvarwa (fetus) panguva yekuzvitakura. Inowanikwa mune amniotic sac.

Paanenge ari mudumbu, mwana anoyangarara muamniotic fluid. Huwandu hweamniotic fluid hwakanyanya pamasvondo makumi matatu nemana (gestation) kupinda mudumbu, kana ichiita 800 mL. Anenge mazana matanhatu emamirioni amniotic fluid akakomberedza mwana panguva yakazara (makumi mana evhiki yekubata).

Iyo amniotic fluid inogara ichifamba (kutenderera) apo mwana anomedza uye "kufema" iyo fluid, uye ozoiburitsa.

Iyo amniotic fluid inobatsira:

• Mwana ari kukura kuti afambe mudumbu, izvo zvinobvumidza kukura kwakanaka kwepfupa
• Mapapu anokura zvakanaka
• Inodzivirira kumanikidza kwembilical tambo
  
• Chengetedza tembiricha yenguva dzose kutenderedza mwana, kudzivirira kubva pakurasikirwa kwekupisa
• Dzivirira mwana kubva mukukuvara kwekunze nekusimbisa kurova kamwe kamwe kana kufamba

Yakawandisa amniotic fluid inonzi polyhydramnios. Aya mamiriro anogona kuitika nekuwanda kwepamuviri (mapatya kana matatu), congenital anomalies (matambudziko aripo kana mwana achizvarwa), kana gestational chirwere cheshuga.

Zvishoma amniotic fluid inozivikanwa se oligohydramnios. Aya mamiriro anogona kuitika nekunonoka kubata nhumbu, kuputika kweiyo membreni, kusagadzikana kwepashure, kana kusagadzikana kwe fetus.

Izvo zvisina kujairika amniotic fluid zvinogona kukonzeresa mupi wezvehutano kuti atarise nhumbu zvakanyanya. Kubvisa sampuro yemvura kuburikidza neamniocentesis kunogona kupa ruzivo nezve bonde, hutano, uye kukura kwemucheche.
