Not sure if this is a rhetorical question, as it asks for 'two' functions, but: Contractions open the cervix, and also help to move the baby down the birth canal.
Barrier islands serve as natural protection against storm surges and coastal erosion by absorbing the energy of waves and hurricanes. They also provide important habitats for wildlife and serve as nesting grounds for shorebirds and sea turtles.
If your contractions are three min. apart then you probably already are in labor especially if you are already dilated and 80% effaced. If the contractions aren't regular then you aren't in labor but if it turns out that your not then you will most likely be going into labor really soon.
Contractions can start two weeks before the due date to two weeks after.

Contractions can lead to labor so you shouldn't take them in a non serious manner.

I had the same thing happen and when I went to the dr. she told me that I was in "early labor". She also informed me that early labor can last hours, days, or even a week or two. Rest assured active labor isn't too far off. Your contractions were that bad and you didn't go to the hospital? You should at least call your doctor. It is unlikely that if you were in true active labor that your contractions would stop with a change in position or moving around. If they stop or get easier to bear when you move around, they are probably Braxton Hicks. I would call the doctor anyway just to be sure.
