Isakhiwo umzimba female: izici yokwakheka bokuphila

Morfoanatomicheskoe umehluko phakathi kobulili ezimbili unegama ethize. Ngo biology, lesi simanga libizwa dimorphism ngokobulili. Kanjalo yokwakheka bokuphila umehluko amadoda abesifazane ngempela ebanzi, ngenxa nesidoda okunikelwe, ikakhulukazi, ukuba ezimbili-X-chromosomes e uhlobo ngokobulili. Lesi sici ngowokuqala, isivele sobala ezingeni zygote. Eqinisweni, lokhu kusho ukuthi ezingeni yeseli elilodwa kusukela lapho umbungu okhula ngayo kamuva, kungenzeka ukuba wahlulele umehluko ngokobulili. Nokho, kubonakala sengathi kuphela ezingeni izinhlayiya eziyisisekelo zofuzo.

Isakhiwo yokwakheka umzimba female

Iqhaza begazi besifazane kwemiphakathi womuntu - okhulelwe ingane nokubeletha. Ngaphakathi accordance nga lo uhlelo kwezitho abantu besifazane Ubuningi bamahora ingashintshwa ukuze afeze le nqubo. Kufanele ukugqamisa kwezitho zobulili e isakhiwo yokwakheka. Ngenxa umehluko isakhiwo kanye physiology ukusebenza izibuya kuhluke.

Phakathi zangasese zesifazane kukhona ukwahlukana kwi yangaphandle futhi ingaphakathi. I organocomplexes yangaphakathi zihlanganisa gonads, amashubhu fallopian, kwesibeletho, esithweni sangasese somuntu wesifazane. Eyokuqala yensimbi ngohlobo okuxubile uketshezi, njengoba synthesize futhi germ cells futhi hormone ocansini ezinethonya bokuphila ku kwayo yonke indikimba yezikhonzi abesifazane. Kwesibeletho yisona sakhiwo lapho umbungu okhula ngaso sonke isikhathi. Ngemva kwesikhathi esithile kokukhulelwa ku ampoule fallopian tube oocyte uhlala ingaphakathi layo. Ukubambezeleka izakhiwo yokwakheka kuholela ukukhula komntwana ethunjini, sihlobene zazo isakhiwo yomzimba wowesifazane alinikezi. Ngakho-ke, uma yezinkinga ezifana yokukhulelwa Kunconywa noma ukunqanyulwa noma umbungu yayo ukudluliswa, nakuba lo msebenzi eziyinkimbinkimbi.

Kwesibeletho kuyinto isitho kwemisipha, ngenkuthalo elikhulu ngesikhathi sokukhulelwa. It has iqoqo umzimba nasentanyeni, obumba insikazi ipheshana zangasese. Ngokusho kwakhe amaseli ubulili besilisa bahlasele kweNdikimba engavamile tube fallopian, lapho iqanda eselivundisiwe.

isakhiwo umzimba yomuntu wesifazane kuncike obalulekile yezinto eziphilayo noma yomthetho, lapho imvelo osinikeza namathuba entuthuko umbungu, kanye kwezidingo. Main isakhiwo ezicacile zomzimba, okuyinto ngempumelelo yakha emgudwini wokuzala kuyinto sangasese. Lokhu umzimba eziyize itholakala ukhalo, nogange lwawo nokukhawulela zomphakathi the ikhanda fetus ngesikhathi sokuzalwa.

Isakhiwo umzimba female: ngemomozi

Ngu yangaphandle Izitho zangasese okubhekiselwe amabele, labia ezinkulu nezincane. Umqondo endalo, lawo kwakhiwa isakhiwo abesifazane kule nqubo ye phylogenesis, futhi itholakala kungenzeka yokondla ingane esanda kuzalwa nge high amandla umkhiqizo, okuyinto imfihlo webele - ubisi womuntu. Inqubo Ukukhetha kungashintshwa bokuphila emzimbeni kwabesifazane. Phakathi nenkathi yokukhulelwa nezindlala ukuthuthukisa, futhi kusukela iminyango secretory izinhlamvu ziqala ukwakheka Amapayipi ukuthi izingxenye endaweni ye ingono. Lokhu ilawulwa hypothalamic-pituitary uhlelo kanye prolactin hormone. Uma owesifazane ukhiqiza ingane ezweni, ugijima inqubo lactation, okusho ukwehlukana ubisi. Kuphela ngenxa ingane yakhe kungenziwa bondliwa ezinyangeni ezimbalwa, bese kudingeka uqale ukusebenzisa instantons okusanhlamvu ukudla kwakhe.

Isakhiwo umzimba female sihlanganisa umthondo asizayo ubekwe ngaphandle. Kuyinto labia. umsebenzi yabo ukuvikela egumeni kusukela Ukungena kwamagciwane. Kulokhu, izindebe labia ibaluleke exocrine nezindlala. Bona secrete imfihlo elimnandi. isidingo sakhe izimo zanamuhla zenhlalo kungukuthi kunakwe, kusukela ekuthuthukisweni lithole yesibili isignali uhlelo yomuntu. Ngaphambili, imfihlo yalezi nezindlala wakhonza ngamazwi isignali ukulungela ngesikhathi sokukhwelana. Kuyaphawuleka ukuthi isakhiwo umzimba female akuyona kuphela kwezitho zobulili ezihlukahlukene, futhi has izici zayo siqu kumthethosisekelo, zokucabanga, uhlamvu.
