How is the vagina adapted to its sexual function?

My teacher gave us an essay title to do and it says 'How is the vagina adapted to its sexual function?'. I am struggling to think of things, it has anti-bacterial properties and is slightly acidic to stop infection etc and the multiple layers of inner epithelial tissue is 'mechanically' strong to withstand damage from the penis. But I can't really think of anything else, this is really annoying me now. I think I have mental block, has anyone done this essay before and can help? Thanks.

From other peoples descriptions, this teatcher sound quite similar to a certain Norwegian teatcher at our school...

it secretes fluid to lubricate (ewwww) during sex, also protects from infection. Strong muscles to withstand sex and childbirth. It also contracts at the point of climax to aid the sperm getting to the egg.

Thats about all i can think of

Hahaha 'withstand sex'. Besides, I know few girls who haven't got much muscles left there...
Anywho, heres the best breakdown I think you'll get...
"How is the vagina adapted to its function"
1) Nervous reflexes to stimulation in the perineal region, and in particular on the cit cause fluid secretions from the glands of bartholin and more importantly the vaginal wall. Basically during sex the blood flow increases in the sexual organs, and this causes transudation of lfuid across the vaginal wall (fluid is squeezed out by the pressure in the capillaries).
2) Only 30-50 percent of women achieve orgasm from coitus (most orgasm during foreplay rather than sex). Therefore, the argument of mulletprincess isn't that important.
3) When the guy ejaculates, the semen is 'sprayed' (lovely thought) onto the posterior of the vagina, and onto the cervical os (opening) youll recall that the vagina goes up and back like this / and cervix goes up and forwardsy like this \.
4) The semen comes out (pun) globby. The acid of the vagina and also i think some enzymes increase the breakdown of this structure. This causes the semen to become alot more fluid. The sperm can then attempt to swim into the cervix. Once there they go into the crypts and are released slowly over a period of days. Some semen of course will run out of the vagina (hence the bed time wet patch) infact 99% of sperm are lost this way.

Cant think of anymore at the mo...far as i remeber the cervix and uterus are where everything interesting happens!

not really relevant but quite interesting.

Bit more relevant - Vasocongestion is what causes the vagina to lubricate itself, and vasocongestion is caused from an engorgement of the blood vessels in the semi-porous vaginal walls. The stuff vasocongestion creates is lubricant.

None of those links actually mention sex in detail they are about the science of the vagina and womans sexual organs which is a subject that i think is interesting and relates directly to the question which started the thread. We hear enough about what men like and how mens sexual organs function and that is never seen as inappropriate so I really dont see why this should be taboo, but mods feel free to delete them if you think they are inappropriate.

I think that knowing about the science of the vagina would probably lead to far better sex anyway. Most men dont seem to have a clue about what turns a woman on.
