What are the sympathetic nervous system responses?

For example, the sympathetic nervous system can accelerate heart rate, widen bronchial passages, decrease motility of the large intestine, constrict blood vessels, increase peristalsis in the esophagus, cause pupillary dilation, piloerection (goose bumps) and perspiration (sweating), and raise blood pressure.

What is sympathetic nervous system and parasympathetic nervous system?

The autonomic nervous system comprises two parts- the sympathetic and parasympathetic nervous system. The sympathetic nervous system activates the fight or flight response during a threat or perceived danger, and the parasympathetic nervous system restores the body to a state of calm.

What is an example of the sympathetic nervous system at work quizlet?

An example of a sympathetic response can be pupillary dilation, increased heart rate, increase in blood pressure, dilation of blood vessels, and an increase in glucose production.

What are the primary functions of the sympathetic?

The sympathetic nervous system’s primary process is to stimulate the body’s fight or flight response. It is, however, constantly active at a basic level to maintain homeostasis.

What are the major functions of the parasympathetic nervous system?

The parasympathetic nervous system is responsible for the body’s rest and digestion response when the body is relaxed, resting, or feeding. It basically undoes the work of sympathetic division after a stressful situation. The parasympathetic nervous system decreases respiration and heart rate and increases digestion.

What are the effects of the sympathetic nervous system on the body?

eg, the sympathetic nervous system can accelerate heart rate, widen bronchial passages, decrease motility (movement) of the large intestine, constrict blood vessels, cause pupil dilation, activate goose bumps, start sweating and raise blood pressure.

What is the parasympathetic nervous system quizlet?

The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body’s rest-and-digest response. … Its general action is to mobilize the body’s fight-or-flight response.

How do the sympathetic and parasympathetic nervous systems work together quizlet?

Briefly explain how the sympathetic and parasympathetic nervous systems work together to help us respond to events. Sympathetic increases heart rate and blood pressure and parasympathetic calms it back down.
