This might help you visualize things.

You have a data path through the ALU (and later the CPU) that is sixteen bits wide. That data path is like a set of water pipe that flow through a bunch of valves. Those valves, based on the control signals, pick which pipes are allowed to send their data to the next part of the machine.
