Uhlelo lokuzala lwesifazane lunomshini onzima kakhulu. Ngakho-ke, esimweni sesimiso sokuzala, izinhlaka zangaphandle nezangaphakathi zihlukaniswa. Okokuqala kungabandakanya ama-labi amancane nezinkulu, i-pubis ne-clitoris.
Izitho zangasese ezingaphandle
Lebibi ziyizibili zombili zesikhumba esikhombisa ukuvulwa kwesisu bese wenza umsebenzi wokuzivikela. Ngenhla, esikhundleni sokuxhumeka kwabo, kukhona i-clitoris, esakhiweni sayo esilingana ngokuphelele nelungu lesilisa. Uyakwandisa usayizi ngesikhathi sokulala ngokobulili futhi kuyindawo engavamile yowesifazane. Ukuphelele kwezitho ezibalwe ngenhla nokubizwa kuthiwa i-vulva.
Izitho zangasese zangaphakathi
Izitho zangaphakathi ezakha uhlelo lokuzala lomfazi zizungezwe ngokuphelele nxazonke ngamathambo e-pelvic. Lokhu kufaka:
- 2 ama-ovari;
- Isibeletho esinamashubhu;
- umlomo wesibeletho wesibeletho ;
- ubulili.
Isibeletho sitholakala ngqo phakathi kwesikhumba, ngemuva kwesikhumba nangaphambi kwe-rectum. Ixhaswe ngemigudu emibili yokuqina, ewugcina unomphela endaweni eyodwa. Liyilungu elingenalutho elinesimo esenziwe nge-pear. Izindonga zalo ekubunjweni kwayo ziqukethe isendlalelo semisipha, esinezinkontileka ezinkulu kanye nokunciphisa. Yingakho isibeletho sanda kakhulu usayizi ngesikhathi sokukhulelwa, njengoba ingane ikhula. Ukubuyiselwa kwakhe emva kokubeletha kwesayizi sangempela kwenzeka emavikini angu-6.
Umlomo wesibeletho ukuqhubeka komzimba wakhe. I-tube encane enezindonga ezinamandla futhi iholela engxenyeni engenhla yelungu. Ngosizo entanyeni, kukhona umlayezo wesigcawu se-uterine nesiswini.
I-vagin isakhiwo sayo sifana nethubhu, ubude bayo buyi-8 cm ubude. Kungenxa yalesisiteshi ukuthi i-spermatozoa ingena esibelethweni. I-vagina ine-elasticity enkulu, evumela ukuthi yande ngesikhathi senqubo yokulethwa. Ngenxa yenethiwekhi ethuthukile yemithambo yegazi, ngesikhathi sokulala ngokobulili i-vagina ivuvuka kancane.
Amapayipi yindawo lapho i-sperm ihlangana neqanda emva kokuvuthwa. Ubude be-tubspian tubes buba ngu-10 cm. Baqeda ukwandiswa kwemifula. Izindonga zabo zangaphakathi zimbozwe ngokuphelele ngamaseli we-epithelium enamafutha. Kungenxa ngosizo lwabo ukuthi iqanda elivuthiwe lihambela egumbini lesisu.
Ama-ovariya ayingxenye yesimiso se-endocrine yowesifazane futhi yizigulane zokufihla okuxutshwe. Zivame ukutholakala ngezansi kwenkaba emgodini wesisu. Kulapha ukuthi ukukhiqizwa kweqanda nokuvuthwa kwenzeka. Ngaphezu kwalokho, zenza ama-hormone amabili anomthelela omkhulu emzimbeni - i-progesterone ne-estrogen. Ngisho nasekuzalweni kwentombazane emaqanda ama-ovari kunamaqanda angaba ngu-400 000. Njalo ngenyanga, phakathi nonyaka wonke wokubeletha wesifazane, iqanda elilodwa likhula, elishiya isisu esiswini. Le nqubo ibizwa ngokuthi i-ovulation. Uma iqanda lingeniswa, ukukhulelwa kuyangena.
Izifo ezenzekayo zesistimu yokuzala
Ukuze ugweme ukuthuthukiswa kwezifo, wonke owesifazane kufanele azi ukuthi indlela yakhe yokuzala ihlelwe kanjani. Izifo zesimiso sokuzala zowesifazane zihluke kakhulu futhi ezimweni eziningi ziyimbangela yokungasebenzi.
Ngokuvamile, ukuthuthukiswa kokungajwayelekile esimisweni sokuzala kowesifazane kungabonwa. Njengomthetho, lokhu kwenzeka ngesikhathi se-embryogenesis. Izibonelo zezinkinga ezinjalo zingafaka i-agenesis yesisu, i-agenesis yomlomo wesibeletho, i-uterine agenesis, i-tubal agenesis, nezinye iziphambeko.
