Verified step by step guidance

Understand the autonomic nervous system (ANS): The ANS is a part of the peripheral nervous system that controls involuntary physiological functions such as heart rate, digestion, and respiratory rate. It is divided into the sympathetic, parasympathetic, and enteric divisions.

Define the 'fight or flight' response: This is a physiological reaction to a perceived threat, preparing the body to either confront or escape the danger. It involves increased heart rate, dilation of airways, release of adrenaline, and other changes to enhance physical performance.

Identify the division responsible for the 'fight or flight' response: The sympathetic division of the ANS is responsible for activating the body's 'fight or flight' response. It mobilizes energy and resources to handle stressful situations.

Differentiate the other divisions: The parasympathetic division is associated with 'rest and digest' functions, promoting relaxation and energy conservation. The enteric division controls gastrointestinal functions independently of the brain. The somatic division, while part of the peripheral nervous system, controls voluntary movements and is not part of the ANS.

Conclude that the correct answer is the sympathetic division, as it is specifically characterized by the 'fight or flight' response.
