Ethereum implements an execution environment on the blockchain called the Ethereum Virtual Machine (EVM). Every node participating in the network runs the EVM as part of the block verification protocol. They go through the transactions listed in the block they are verifying and run the code as triggered by the transaction within the EVM.
