Verified step by step guidance

Understand the roles of the sympathetic and parasympathetic divisions of the autonomic nervous system. The sympathetic division is often associated with 'fight or flight' responses, while the parasympathetic division is associated with 'rest and digest' functions.

Analyze the first statement: 'The parasympathetic division dilates the bronchioles.' Typically, the parasympathetic division constricts bronchioles to conserve energy, so this statement is incorrect.

Evaluate the second statement: 'The sympathetic division decreases heart rate.' The sympathetic division usually increases heart rate to prepare the body for action, so this statement is incorrect.

Consider the third statement: 'The parasympathetic division increases digestive activity.' This is correct because the parasympathetic division promotes digestion and other maintenance activities.

Review the fourth statement: 'The sympathetic division constricts the pupils.' The sympathetic division actually dilates the pupils to allow more light in during a 'fight or flight' response, so this statement is incorrect.
