I-vagina (isisu), isibeletho, amashubhu wezintambo nama-ovari yizitho zangaphakathi zobulili zowesifazane. Njengomkhuba wokubonisa, abesifazane abaningi abazi ulwazi oluqondile mayelana nesakhiwo sohlelo lwabo lwezocansi njengalokhu, noma ukuthi i-vagin ihlelwe kanjani ikakhulukazi.
Ubunjani?
Ngakho-ke, yikuphi ukubekwa kanye nesakhiwo sobulili besifazane. I-vagina iyisitho esincane se-pelvic, phambi kwayo sitholakala i-urethra nesinye, ngemuva - i-rectum. Ingxenyeni engezansi yelungu lilinganiselwe ngendlini yesifazane (i-labia encane, i-clitoris ne-hymen (kusuka ezintombi) noma izinsalela zayo (kwabesifazane abaphila ngokocansi)), ingxenye engaphezulu ngokusebenzisa umlomo wesibeletho ixhunywe esibelethweni ngokwazo.
Isakhiwo sobulili besifazane silula. Eqinisweni, ubukazi bungumngcingo omncane we-muscular, ngaphakathi lapho kunenqwaba yamapulangwe, elula echaza ukuqina kwawo okuphakeme. Ingxenyeni engenhla ye-vagin ivinjiwe kancane, i-elastically more than the lower.
Idivaysi yesisindo ifana nabo bonke abesifazane, okwamanje njengoba ubukhulu bayo bodwa ngokuqondile. Ubude obujwayelekile besifazane buyi-8 cm, kodwa ngenxa yezici eziphathelene nesakhiwo sesimiso sokuzala sowesifazane ngamunye, lesi sibonakaliso singaba ngaphansi kuka-6-12 cm. Ubukhulu bezindonga zangasese, njengokubusa, akudluli 4 mm.
Ukwakhiwa kwesifazane
Ukwakhiwa kwezindonga zangasese nezangemva kwebesifazane kulandela lokhu:
- ungqimba lwangaphakathi (ulwelwesi lwamangqamuzana);
- isendlalelo esiphakathi (isethi semisipha encane);
- ungqimba wangaphandle (izicubu ezixhunyiwe).
Ingqimba yangaphakathi yelungu lihlanganiswe ne-epithelium ehlungwe, ngenxa yokuthi ukuqina kwayo okuphezulu kuqinisekisiwe. Isakhiwo esinjalo esibanzi sivumela ubulili ukuba bubhekane nobukhulu obukhulu ngesikhathi sokubeletha . Ngaphezu kwalokho, "ukukhwabanisa" kwesisindo kuphakamisa lonke uhla lwezinzwa phakathi kocansi. Kumele kuqashelwe ukuthi ukufakwa okunjalo kubonakala kuphela kwabesifazane abaneminyaka yobudala.
Idivaysi yesigcawu esingaphakathi kwesisindo sichazwa yizicucu ezibushelelezi eziqondiswa isikhathi eside, ezingxenyeni ezingenhla zangasese zihamba kahle zibe izihlungwini zesisu, futhi engxenyeni engezansi - zinamandla amakhulu futhi ziyafakwa emisipha ye-perineum.
Isakhiwo sezingxenyeni zangaphandle zesisindo yisisindo esixhumeneyo, lapho i-vagina ihlukanisa khona ezingxenyeni ezingahlotshaniswa nesistimu yokuzala yesifazane: phambi - kusukela engxenyeni engezansi yesigqila, kusukela ngemuva - ukusuka emgqeni.
Umsebenzi wama-vaginal kanye nokukhishwa kwesisu
Zonke izici zesakhiwo sobulili besifazane zithatha ukubaluleka kokusebenza kwazo:
- i-vagina ihileleke ngqo ekuziphatheni ngokobulili, ikhuthaza ukuhamba kwesidoda emgodini wesibeletho somlomo wesibeletho ;
- Ukukhipha igazi kukhishwa ngesisu;
- yiyona kuphela isiteshi sokuhamba kwemfihlo yemvelo ezivela ezingxenyeni zangaphakathi zobulili zangaphakathi;
- i-vagina iqhaza ngokuqondile enkambeni yobudala, kuyo, njengalokhu ngokusebenzisa umsele wokuzala, nokuthuthukiswa kwengane;
- yenza umsebenzi othize wokuzivikela, ngenxa yedivayisi ekhethekile yesisindo, ingozi yokulimala nokutheleleka kohlobo lokubeletha kunciphisa;
- ukutholakala kwesifo sezinzwa emgodini kumenza abe yindawo ehlukumezayo yowesifazane, futhi, ngokusho kocwaningo olwenziwe, lusephambili
Udonga lwesiswini yilona iphuzu elidumile G.
Ukwakhiwa kwezindonga zesifazane wesifazane kubandakanya izigulane ezithile, umsebenzi ozokwenza ukuthungatha umcibisholo wokucwilisa nokuhlanza ubulili. Ngaphandle kwe-mucus ekhishwa yi-vagin enempilo (okungukuthi, ubulili, hhayi isisu noma umgudu womlomo wesibeletho sayo), ludutshulwa ngokweqile noma lingakhulumi ngaso sonke isikhathi (kufakwe endaweni yangakini). I-membrane ye-mucous ye-vagina ihlushwa izinguquko ezingadingekile ohlelweni lokuya esikhathini, kuye ngokuthi isigaba somjikelezo, ukwenqaba ezinye zezingxenye zayo ze-epithelial kwenzeka.
