What occurs when the sympathetic nervous system is stimulated?
No explanation
When the sympathetic nervous system is stimulated, it activates the "fight or flight" response, which prepares the body for physical activity or stressful situations. This response includes several physiological changes, such as:
Increased heart rate and cardiac output: The sympathetic nervous system releases adrenaline and noradrenaline, which increase heart rate and cardiac output to provide more oxygen and nutrients to the muscles.
Decreased uterine activity: The sympathetic nervous system inhibits uterine contractions to prevent
premature labor.
Decreased pancreatic activity: The sympathetic nervous system inhibits insulin secretion and promotes glucagon secretion to increase blood glucose levels.
Decreased gastrointestinal activity: The sympathetic nervous system inhibits digestive functions to divert blood flow to the muscles.
