Here's the context.
Blushing from embarrassment is governed by the same system that activates your fight-or-flight response: the sympathetic nervous system.
And I'd like to know the difference between that and as here.
- Blushing from embarrassment is governed by the same system that activates your fight-or-flight response.
The system that governs the blushing from embarrassment
The system that activates your fight or flight response
are exactly the same thing, right? but, when it comes to using 'as' like #2,
- Blushing from embarrassment is governed by the same system as activates your fight-or-flight response
The system that governs the blushing from embarrassment
The system that activates your fight or flight response
are similar.
From the context, the two system is referring to the exact same thing "the sympathetic nervous system", and that's why the author used that rather than as. Am I right to think this way?
