Ubulili besifazane, esakhiweni salo, luyi-tube ethintekayo elinezicubu ezinamahlombe. Ubulili buqala kusukela engxenyeni yomlomo wesibeletho futhi buphela nge-genitalia yangaphandle (vulva).
Ubukhulu besisindo buba ngu-7 - 12 cm ubude futhi ububanzi buka-2-3 cm. Ubuningi bezindonga zelungu liwu-3 - 4 mm.
Isakhiwo sezindonga zesifazane
I-anatomy yesakhiwo sezindonga zelungu limelelwa ngamatshe amathathu:
- Isendlalelo sama-mucous - igobolondo eliphindiweyo eliphethwe, elikwazi ukwelula nokwenza isivumelwano. Lesi sakhiwo sivumela abesifazane ukuba babe nobulili futhi kubalulekile ekubelethweni kokuhamba kwengane ngokusebenzisa i-canal yokuzalwa.
- Ingqimba engaphakathi yodonga lwangasese yisisipha, esakhiwe yizinwele ezibomvu ze-longitudinal muscle. Ingqimba yesibili yesitho sangasese ifakwe esibelethweni kanye nezicubu ze-vulva.
- Ingqimba yangaphandle yezicubu ezixhumeneyo zivikela ubulili ngokuxhumana nomathumbu nesisu.
I-vagina inemibala ebomvu ebomvu, izindonga zayo zilula futhi zifudumala.
I-microflora yesifazane
I-mucosa yama-vaginal igcwele microflora, ikakhulukazi bifidobacteria ne-lactobacilli , peptostreptococci (ngaphansi kuka-5%).
Isimiso yisimo semvelo esiyinkimbinkimbi ye-vagin: nayo umsebenzi obalulekile we-microflora enempilo igcinwa, futhi amabhaktheriya e-pathogenic abhujiswa. Imvelo yemvelo, ngokuphambene nalokho, ibangela ukwephulwa ebhaleni likalenta. Lokhu kuholela ekutheni i- bacteriosis ye-vaginal , kanye nokuthuthukiswa kwefloral fungal edala i-candidiasis.
Olunye umsebenzi wendawo yemvelo ye-vagin ukukhethwa kwemvelo kwe-spermatozoa. Amandla angcolile, amancane amancane wesilisa angaphansi kwamandla e-lactic acid ahlongakala futhi angenalo ithuba lokutshala iqanda ngamagciwane angasebenzi kahle.
Ukugcina ukwakheka kwebhaktheriya evamile kwesiswini kanye nezinga le-asidi kuyisihluthulelo sempilo yamalungu esitho zangasese. Endabeni yezifo ezivuthayo kanye nesidingo sokwelashwa kwama-antibiotic, kubalulekile ukuthatha amalungiselelo okugciwane ukuze ubuyisele i-biocenosis evamile yesisu.
