Ukuqonda Umsebenzi Walo Kusuka ku-Arousal kuya ku-Childbrith
I-vagina yi-tube ye-muscular ehlinzeka indlela yokuphuma ngaphandle komzimba esibelethweni (isibeletho). I-vagina inekhono lokuguqula usayizi ukuze ulale ubulili futhi unikeze "umsele wokuzalwa" lapho umntwana angathunyelwa khona.
Ukwakhiwa kweVagina
Ubulili lwakhiwa izicubu, izintambo, imisipha, nezinzwa. Izicubu zomzimba zangaphandle zixhaswa ngendwangu yezicubu ezixhumene ezisebenza ndawonye ukuze zikhiqize i-mucus ye-lubrication yesisu.
Ngaphansi kwalokhu ungqimba lwe-muscle olubushelelezi, olukwazi ukuvumelanisa nokwandisa, olulandelwe olunye uhlaka lwamathambo axhumeneyo owaziwa yi-adventitia.
Ubulili bubekwe phakathi kwe-vulva (i-genitalia yangaphandle) nomlomo wesibeletho (i-intambo encane, entanyeni ehlukanisa isisu kusuka kwesibeletho).
Isakhiwo esiphezulu sesiswini sendlela elandelayo:
- Ukuvulwa kwesifazane kulele phakathi kwe-anus kanye nokuvulwa kwe-urethra (lapho umchamo uphuma khona emzimbeni). Ukuvuleka kwesisu nangesifo sokubeletha kuvikelwe yilabiya.
- Ngaphansi kwe-urethra kukhona i-introitus, ebizwa nangokuthi i-vestibule noma ukuvulwa kwesifazane.
- I-vaginal canal ihambela phezulu nangemuva, phakathi kwe-urethra ngaphambili kanye ne-rectum ngemuva.
- Njengengxenye ekude yegciwane lesiswini , i- ectocervix (ingxenye yangaphandle yomlomo wesibeletho) iqhuma ngokujulile emgodini wesisu.
Ubude besifazane buyakwazi ukuhluka phakathi kwabesifazane abaneminyaka yobudala bezingane eziphakathi kuka-2.5 intshi kuya ku-3.5 amasentimitha ngokwesilinganiso.
Ngokuphathelene nokugcoba, ukuvinjelwa kwamagciwane kungakhula ngesikhathi sokuvuthwa ngokocansi, ukukhulelwa, nezigaba ezahlukene zokuya esikhathini. Ngesikhathi sokuya esikhathini, i-membrane yamangqamuzana iyodla futhi ukwakhiwa kwe-mucus kuzoshintsha ukuze kube lula ukukhulelwa.
Ubulili nobulili
Ngesikhathi sokuvuthwa kocansi, i -membrane ye-mucosal ye-vagin izoqala ukukhiqiza ukushisa okuningi njengoba ubulili bukhula kabili ubude nobubanzi.
Lokhu kunciphisa ukungqubuzana kanye nobungozi bokulimala ngesikhathi sokungena kwesifazane.
I-vagin iyakwazi ukuqhubeka nokwandisa njengoba owesifazane evuselwa ngokugcwele njengoba umlomo wesibeletho uthatha uhlangothi oluhlukile futhi uqala ukuhoxisa. Lokhu kungabangela ukuba isibeletho sikhuphuke esikhwameni bese sakha lokho okubizwa ngokuthi "umphumela wokubala" lapho izindonga zangasese zilula khona futhi zenze isivumelwano ngokuzungeze ipenisi ukunikeza ukukhuthazwa nokukhuthaza ukujula .
I-vagina ngokwayo ayinaso iziphetho eziningi zesibindi yingakho abesifazane abaningi bengakwazi ukufeza ukukhushulwa ngokocansi kusuka ekungeneni kwesisu. Ngakolunye uhlangothi, i- clitoris inomsoco futhi ingasebenza ngendoda ukuze ifegasgasm ngesikhathi socansi.
I-Vagina ekubelethweni kokubeletha
Ngesikhathi sokubeletha, ubulili buhlinzekela indlela ingane okukhululwa ngayo. Lapho kuqala ukubeletha, owesifazane ovame ukuzwa ukukhulelwa kwamagciwane, ukuvinjelwa kwemisebenzi, ukwehlukana kwamagundane, noma ukuqubuka kwamanzi noma amashiotic kwamanzi.
Njengoba ukulethwa kusondela, umlomo wesibeletho uzoqala ukwehlisa umzimba nokunciphisa, ukuvumela ingane ukuba iwele ngaphansi kwekhanda. Ingane izoqala ukulahlekelwa ukusekelwa komlomo wesibeletho njengoba ukuqala kwezinhlangothi kuqala futhi i-os yomlomo (ukuvulwa) iqala ukuhlanza.
Lapho ukuhlunga kwesibeletho kukhulu kunamasentimitha ayishumi (10 cm), umntwana uzodlula esibelethweni angene esiswini. Isakhiwo sobulili sinjalo kangangokuthi sikwazi ukwelula izikhathi eziningi ububanzi bayo obujwayelekile ukuze kutholakale ukulethwa.
Ukulandela ukukhulelwa nokubuya kwe- flowrogen e-estrogen evamile , ubulili buzobuyela esimweni sokuqala sokukhulelwa cishe emavikini ayisithupha kuya kwangu-8.
