The vagina is often confused with the vulva (which is the anatomical structure I’ll be covering next). The vagina is also referred to as the vaginal canal or vaginal tract. It is a muscular tube that runs from the cervix to the external genitalia.

Some of its functions include:

• providing an exit route for menstrual blood and tissue.
• role in sexual arousal and pleasure. 
• providing a passage for sperm to enter and a baby to exit.
• offering immune defense.

It has an acidic pH of 3.8-4.5 and lots of local flora and bacteria similar to how our gut has a microbiome. This acidic pH and microbiome are important for vaginal health. This is why the use of soaps internally is not recommended. Good old water is what works best.
