Where does a gas-fired oven get oxygen for combustion?

The following question is banned as not asking for improvement, despite the same is highly appreciated.

Where does a gas-fired oven get oxygen for combustion? [on hold]

Where does a gas oven get oxygen for combustion? It is not a question for the burners which are located at the top of the stove. Open burners simply use the oxygen from the open air. As soon as gas touches the open air, it burns. But how can that happen in the closed environment within the oven?
The oven is isolated from the air in order to keep the temperature high within it. But, this conflicts with the possibility to have the flame there -- the oxygen is quickly consumed by combustion and the flame should go extinct. How do they manage to burn it in the isolated oven?
