It is your fight of flight response, your body jumps to make ready and your brain tunnels on the threat. it is a byproduct of the evolution of our species.
When we startle we come to attention, assess the treat and either fight or run.

Its a reflex. Same reason why your foot is supposed to kick or lift up when the doctor hits you in a certain spot in the knee

Any of the above are good answers but maybe thinking about something else so we would be caught off guard. I wonder if it can be relayed to anxiety.

It's part of the "fight or flight" response our nervous system responds to from the sudden surge of adrenalin.
