You put the pill between your knees and hold it there whenever you are with a guy who you really really really like. Works every time and is 100% effective!

They mess up the homone cycle of the body so that the uterus, instead of getting ready to receive an egg, thinks it already has one and won't accept another. The long term pills keep it in this condition for longer than 21 days. The demonstration of this is the period that occurs at the end of the active pills. The period (menses) is the shedding of the inner lining of the uterus (womb) that was ready for an egg.
Other methods of birth control irritate the uterus (IUD) or physically block the sperm from getting to the egg (diaphragm or condom) or try to avoid the time when the woman is fertile (rhythm method)

I think Alpla has the best answer. While some birth control pills affect ovulation, others make the uterine lining less receptive to sperm. In order for conception to take place, the sperm must fertilize the egg which then attaches to the uterine wall where it develops into the embryo. Some birth control pills inhibit this process.

Birth control pills send out hormones that mimic pregnancy. These "hormonal messengers" then shut down the ovulation cycle. If no eggs get released, no pregnancy can occur

Most birth control pills are estrogen-based and fool the body into thinking it's pregnant already. By doing so your body will not produce ovaries during your regular 28-day cycle. You will only take the pills for 28 days, and then you will abstain from them for 4 days or until menstruation ceases for that cycle.

The common theory is that they interrupt the play between pitutary gland and ovaries that trigger ovulation. Plus they modify the mucus of the cervix of uterus so it's less friendly to sperm.
Now the real truth is nobody knows for sure how and why they work.

They make you body produce too many (or too little) hormones to get pregnant. Some times your body will not release eggs until hormone levels are sufficient. (Thus some people have twins or triplets when they stop taking birth control)

By supplying the body with certain hormones which are normally created in pregancy. The female body conserves its eggs, and does not produce or release them if a pregnancy is in progress.

the hormones in birth control pills sort of "trick" your body into thinking it is already pregnant, so your ovaries do not release eggs.

she asked how do they work not what do they do...... what is best is that you talk to and OG-GYN and have them best explain it and best choose the right one for you! womens bodies are created different so what may work for your friend may not work for you! Personally i have tried Yasmin and they work fine and i didnt see any changes in my body, except for the fact that i never got pregnant, and i dont want to sound like one of those commmercials but it doesnt protect you from STD/AIDS or anything else so please be carefull
