What is the purpose or function of the sympathetic nervous system quizlet?

The sympathetic nervous system arouses the body and expends energy. It is responsible for our fight and flight response. The parasympathetic nervous system calms the body and conserves energy.

What happens if the sympathetic nervous system is damaged?

It can affect blood pressure, temperature control, digestion, bladder function and even sexual function. The nerve damage interferes with the messages sent between the brain and other organs and areas of the autonomic nervous system, such as the heart, blood vessels and sweat glands.

How does the sympathetic nervous system affect the eyes?

Stimulation of the autonomic nervous system’s sympathetic branch, known for triggering “fight or flight” responses when the body is under stress, induces pupil dilation. Whereas stimulation of the parasympathetic system, known for “rest and digest” functions, causes constriction.

How does the sympathetic nervous system affect blood pressure?

These sympathetic influences work in conjunction with parasympathetic influences on the SA node to decrease heart rate. During a short-term decrease in blood pressure, the opposite occurs, and the autonomic nervous system acts to increase vasoconstriction, increase stroke volume, and increase heart rate.
