Harry is driving on the interstate highway for the first time since he obtained his license. he is nervous and wants to get off the interstate but cannot do so; his heart and pulse are racing. in this scenario, harry’s physiological responses can be best attributed to his nervous system.

The correct answer will be- sympathetic nervous system

Explanation:

The sympathetic nervous system is a part of the autonomic nervous system which is involved in controlling the autonomous functions of the body. The sympathetic nervous system controls the fight or flight response of the organism as it gets activated during these conditions.

The neurons produce a nor-adrenaline hormone which elicits the production of adrenaline from the adrenal medulla and causes the body to a response like a pupil dilates, the blood pressure increases, the heartbeat increases and sweating.

Since in the given conditions, Harry's heartbeat and pulse rate get increased due to activation of his sympathetic nervous system caused by first time experience of driving.

Thus, sympathetic nervous system is the correct answer.
