The basic design of a gas water heater uses an insulated storage tank. Inside the tank is a steel coil with one or more burners below it.

When you turn on a hot water faucet, hot water is pushed out of the storage tank, which forces cold to the bottom of the tank, where it can be heated at a temperature. The water tank on the top then flows through the coils, where it is heated by natural gas burners inside. The pressure relief valve allows excess pressure to escape inside the tank if necessary.

A drain valve and spigot are also attached to the bottom of the storage tank. So you can drain it and clean any sediment accumulated over time.
