The answer is sympathetic; parasympathetic.

The sympathetic nervous system prepares your body for an intense activity. It accelerates the body's processes in case you need to "fight" or run away in response to a stressor. This is the fight-or-flight response that you hear about.

The parasympathetic nervous system, on the other hand, is the calming and relaxing response. It conserves your energy by slowing down the bodily processes. So when you feel no threat it relaxes your body back to normal function. 

Answer: The correct answers for the blanks are-

Sympathetic nervous system and

Parasympathetic nervous system respectively.

Explanation:

The sympathetic nervous system is also referred as '' fight or flight'' system of body as it prepares body for an intense activities during any stressful situation.

It accelerates the processes of body in a way that either body needs to "fight" or run away in response to a particular stressor.

On the other hand, the parasympathetic nervous system is the ''rest and digest'' system of the body. It brings calm and relaxes the body by conserving energy through slowing down the processes taking place. So, when the stressor is gone, the body relaxes and comes back to normal function through parasympathetic branch.
