Quizplus · Accepted Answer

The sympathetic nervous system is responsible for the body's fight or flight response, which involves increased heart rate, blood pressure, and sweating in response to a perceived threat or stressor. In this scenario, Mr. Valdez's fear that his daughter had fallen down the stairs activated his sympathetic nervous system. The parasympathetic nervous system is responsible for the body's rest and digest response, and the somatic nervous system controls voluntary movements of the body. The central nervous system includes the brain and spinal cord, which coordinate and control all bodily functions.
