Does BSC support BNB?

Excuse me, I'm a bit confused about the relationship between BSC and BNB. Can you clarify for me if BSC, or Binance Smart Chain, actually supports BNB, the Binance Coin? I understand BSC is a blockchain network built by Binance, but does it specifically facilitate transactions and smart contract execution using BNB as its native token? I'd appreciate any clarification you can provide on this matter.
