Accommodating and Changeable:
The vagina is a very “elastic” organ, says Christine O’Connor, MD, director of adolescent gynecology and well women care at Mercy Medical Center in Baltimore. It is small enough to hold a tampon in place but can expand enough to pass a child through. This is because the walls of the vagina are similar to those of the stomach, they have rugae, meaning they fold together to collapse when unused, then expand when necessary.
