Answer :
Final answer:
Stimulation of the sympathetic nervous system results in increased heart rate and cardiac output, increased breathing rate, elevated blood flow to skeletal muscles, and a reduction in blood flow to the digestive system. Additionally, it leads to pupil dilation and increased sweat gland secretion, preparing the body for 'fight-or-flight' response.
Explanation:
The sympathetic nervous system is part of the body's autonomic nervous system that prepares the body for strenuous physical activity or stressful situations, often referred to as the 'fight-or-flight' response. When the sympathetic nervous system is stimulated, a number of events occur. Predominantly, there is an increase in heart rate and cardiac output to pump more oxygen-rich blood to the muscles. In addition, breathing rate increases, blood flow to the skeletal muscles elevates, while it decreases to the digestive tract. There is also pupil dilation and increased sweat gland secretion.
