Umzila we iqanda

Emva kokuba isidoda ifika tubes, oko ihlangana iqanda, oko utshabalalisa ingubo protein bebanjwe ngaphakathi. Ngoko kwezichumiso kuthatha indawo, leyo sisiqalo indlela yophuhliso mbungu. Emva kokuba kudityaniswa, izinto zooyise yomama kwakhiwa iqanda - usana olungekazalwa. Iqanda ipasisa kwisigaba esithile yophuhliso, luphawulwa utshintsho quantitative and qualitative. Kodwa ukuze ukuqhubela phambili uphuhliso iqanda kwaba kunokwenzeka, kufuneka i medium zizondlo, ukusuka apho phezu kweenyanga ezisithoba ezilandelayo ziya kwamkelwa izondlo. Loo medium uba esibelekweni.

Ngoko ke, lo iqanda kwi tubes esehlela ngqo wesibeleko. Oku kwenzeka ngenxa yokuba ubukho villi yokungcoliswa ngaphakathi tubes, ekhuthaza iqanda. Ukuba le tubes zizinto ezimbi (azikhuli, ukugoba), umzila we iqanda yi kakhulu inzima, kuba khalo isibeleko kuyingxaki. Kulo mzekelo, i iqanda ukuze zilibaziseke kwimibhobho Imibhobho kwaye iqhotyoshelwe apho. Le nto ibizwa ngokuba ethunjini (noTubhali) ukukhulelwa kunye ifuna ungenelelo lonyango.

Ngokuqhelekileyo, xa isakhiwo eziqhelekileyo tubes aqhamileyo iqanda kulo isibeleko iwela kwisithuba seentsuku ezine. Ngelo xesha, ukuba ukho kweli morula eqongeni, kodwa ukuba ungena isibeleko - kwi blastocyst bakala. Eli nqanaba libizwa luphawulwa into yokuba iqanda ilungele ezintsha. Blastomeres baqala ukwenza embryoblast - inxalenye yayo eya kuqhubeka ukuphuhlisa umbungu, kunye nenxalenye yesibini iiseli - le trophoblast - kubo iya kuba iphakheji ukutya amaqanda (inxalenye aveza imveliso ye trophoblast kamva abe ngumkhaya).

Kweli nqanaba umzila we iqanda sesiqalile nje. Phantsi yempembelelo utshintsho hormone kuyo Alungise wesibeleko. Emva kokuba follicle caphukisayo, lo luteum corpus ibunjiwe, ukhupha kakhulu eli dlala, kwaye ukuba encinane - estrogen. Oku kukhomba hormone isibeleko inwebu kwiinwebu imfuneko ukulungiselela ebhedini yakhe. Utshintsho yokuqala isibeleko ekumgangatho endometrial - ibizwa ngexesha lokukhulelwa decidua. Yintoni umahluko phakathi endometrium elitsha? Eyona osemqoka endometrium - ulwandiso kwi iikhompawundi yayo ziyatyeba bioactive ukuba sikhule mbungu. Le glycogen, mucopolysaccharides, lipids, iityuwa siphande elements, iienzymes, immunoglobulins - bonke bephela zibalulekileyo umzila we iqanda okuqhubekayo uphuhliso ngokupheleleyo olungekazalwa. Kwezinye iimeko, xa kukho iziphene endometrium kunye nemisebenzi yayo, lo mfazi ixesha elide awukwazi ukufumana wamitha, kwaye ngamanye amaxesha ziba engazaliyo.

Ngokwesiqhelo iqanda endometrium umzila ithatha malunga ezimbini iintsuku. Ngeli xesha, endaweni sothimbo (nidation) dilates imithambo yegazi, endometrium eqinileyo. Ezi nguqu ibonisa ukuba isibeleko ukulungele ukwamkela blastocyst. Xa kwamanzi iqanda kulo ububanzi endometrium kuba ngathi zigutyungelwe le villi esibelekweni. Ngamanye amaxesha le uncamathelo kunga ikhatshwe ukopha minor, yona ngokuphosakeleyo ekuqaleni ngenyanga emva kwexesha. Nangona kunjalo, umthamo wegazi incinane kakhulu - amathontsi ambalwa okanye litshatshazi encinane, ngoko oku "ophela" uvinjwa. Umzila we iqanda, iimpawu zazo na umfazi perceptibility, ekuphela kwendlela uzenza waziva, njengoko ntoni phakathi komjikelo, emva ovulation, kodwa kude ekuqaleni menses. Ukuba abesifazane emva kwimijikelo zabo kwaye bazi ixesha ovulation, kokukhona baya nethemba lokukhulelwa. Kuphela inani elincinane ingabasetyhini umzila we iqanda, nemvakalelo nangayiphi na indlela zivele ngexesha umzila. Ngamanye amaxesha uziva esibuhlungu, isicaphucaphu, imvakalelo ubunzima. Noko ke, azikho zibangelwa umzila ngokwawo, kunye notshintsho hormone emzimbeni.
