What does the diaphragm do?

If you mean the body organ, the diaphragm will help you to breath out and in.

If you mean the type of birth control, it blocks the cervix so the sperm won't get in and cause pregnancy.

If you mean a diaphragm in a machine, it is often a membrane, often rubber, that moves back and forth, often for the purpose of pumping things.
