Indawo yowesifazane

Kwabesifazane, ubulili yingxenye yesistimu yokuzala, okwenza imisebenzi eminingana ebalulekile:

1. Ukubamba iqhaza ohlelweni lokukhulelwa. Ukudlula emgodini wesisu, i-spermatozoa ingene emhubheni yesisu nesigqila .
2. Umsebenzi we-Barrier. I-vagin ivikela izicubu ezithinta izifo ezincane ze-pathogenic.
3. Ukubamba iqhaza ekubelethweni. Iyingxenye yomsele wokuzalwa.
4. Ukufundisa. I-vagina ibonisa ukukhishwa kwesisu nesisu.
5. Ucansi - ukuthola ukwaneliswa ngokocansi.

Isakhiwo esibonakalayo se-vagin

Ngesikhathi eside, lesi sitho sinesilinganiso esingu-7-12 cm. Uma lona wesifazane esesimweni esiqondile, ubukazi bugoqa phezulu.

Ubukhulu bezindonga zangasese ngu-3-4 mm. Zinezigaba eziningana:

• zangaphandle (ezenzakalelayo), ezimelelwe izicubu ezixhumene nazo ngezintambo ezinwebekayo nezisisindo;
• maphakathi (imisipha ebushelelezi);
• ngaphakathi (ulwelwesi lomshukela), oluhlanganisa i-planar epithelium ehlukahlukene, eyenza amafolda aguquguqukayo, okuyinto, uma kunesidingo, avumela lesi sigaba ukuba sisule.

Izindonga zelungu libomvu elibomvu esimweni esivamile, ngesikhathi sokukhulelwa kuthola umthunzi obala. Besebenzela izinhlayiya ezifihlekile.

I-vagin ikhona kanjani nokuthi ikhona kuphi?

I-vagin iphakathi kwesigqila kanye ne-urethra ngaphambili, ngemuva kwayo yi-rectum. I-vagin ihlanganisa umlomo wesibeletho, osemngceleni wayo ophezulu nje ezingeni lomlomo wesibeletho. Engxenyeni engezansi ye-vagin iphela ngokuvula kwesisu, evuleka endaweni ebizwa nge-vestibule, engengxenye ye-vulva (izitho zangasese zobulili zangaphandle).

Uma sicabangela ukuthi ubulili bubukeka bunjani emzimbeni wesibindi, khona-ke kudala i-angle evulekile ngaphambili. Ukuxhumana kwe-vagina kanye nesisu kuholela, ukuthi phakathi kwezindonga zelinja isakhiwo esinjengesigwegwe senziwa.

Isisu sithuthuka kanjani?

Kakade ngenyanga yesihlanu yokuthuthukiswa kwe- intrauterine i- vagin isakhiwe ngokugcwele. Ezinganeni, lesi sitho sinama-3 cm ubude. Futhi isikhundla saso sishintsha ngokukhula kwengane. Lokhu kungenxa yenqubo yokunciphisa isisu nesiswini ngokwaso.

Ngenxa yalokho, ubudlelwane babo be-topographic-anatomical buyashintsha. Isibeletho kanye nesiswini ebusheni bomunye nomunye sakha i-obtuse angle.

Kusukela eminyakeni engama-5 ubudala, ubulili buhlala endaweni lapho kuyoba khona kuyo yonke impilo.
