Final answer:
The function not associated with the sympathetic nervous system is 'conserve energy', which is typically managed by the parasympathetic nervous system.
Step-by-step explanation:
The correct option : b
The function that is NOT a sympathetic system function is b. conserve energy. The sympathetic nervous system is responsible for preparing the body for activity and stress, often referred to as the "fight or flight" response. It enhances blood supply to organs, regulates body temperature, directs blood flow to skeletal muscles, adjusts the functioning of the viscera (like increasing heart rate and bronchial dilation), and impacts metabolism through hypothalamic outputs to the endocrine system.\
However, conserving energy typically falls under the purview of the parasympathetic nervous system, which promotes the "rest and digest" state.The sympathetic system also inhibits digestion to prioritize oxygen delivery to muscles. Therefore, conserve energy (option b) is NOT a sympathetic system function.
