What do saints do when we pray to them?

I apologize for this undoubtedly stupid question… but I am a convert so I don’t know everything. When we want to ask a Saint for help, are we asking them to DO something (such as heal someone) or just to intercede with God on behalf of someone? Thank you.

These links should help you better understand the intercession of the saints. If you have any further questions or concerns that are not answered by this, please contact Catholic Answers directly.
