In the cardiovascular system, the nervous system modulates heart rate, contractile strength and vascular tone
SYMPATHETIC NERVOUS SYSTEM
Promotes a "fight or flight" response, corresponds with arousal and energy generation, inhibits digestion:
Diverts blood flow away from the gastro-intestinal (GI) tract and skin via vasoconstriction.
Blood flow to skeletal muscles, the lung is not only maintained, but enhanced (by as much as 1200%, in the case of skeletal muscles).
Dilates bronchioles of the lung, which allows for greater alveolar oxygen exchange.
Increases heart rate and the contractility of cardiac cells (myocytes), thereby providing a mechanism for the enhanced blood flow to skeletal muscles.
Dilates pupils and relaxes the lens, allowing more light to enter the eye.
PARASYMPATHETIC NERVOUS SYSTEM
Promotes a "rest and digest" response; promotes calming of the nerves return to regular function, and enhances digestion.
Dilates blood vessels leading to the GI tract, increasing blood flow. This is important following the consumption of food, due to the greater metabolic demands placed on the body by the gut.
The parasympathetic nervous system can also constrict the bronchiolar diameter when the need for oxygen has diminished.
During accommodation, the parasympathetic nervous system causes constriction of the pupil and lens.
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients.
Is also involved in erection of genitals, via the pelvic splanchnic nerves 2-4.

The nervous system affects the kidneys by modifying renin secretion
In addition to those visceral functions, the nervous system works with the special senses (vision, hearing), the general sense *pain and temperature sensation on the skin, body movement and position sense. It also controls the musculoskeletal sytem and connects to various glands.

∙ 14y agoThe nervous system works with every system because it spreads around your whole body, the brain commanding what to move & what to do while also getting information from the spinal cord with something such as pain, pleasure or heat.

What is a sentence using the word nervous system?
your nervous system is always at work!

What two systems work with the muscular system?
The two systems that work with the muscular system is nervous system and circulatory system:) ur welcome
What are the 2 divisions of the nervous system and their work?
there aren't 2 divisions of the nervous system. (:
Does the nervous system work with the skeletal system?
The nervous system mainly works with the brain and peripheral nervous system. The skeletal system is comprised of bones. How ever the nervous system helps the skeletal system move.
What system does the muscular system work with closely?
Nervous system
How does the excretory system works with the nervous system?
it all work together the nervous system works with every single system
Why are nervous system important?
because most systems work hand in hand with the nervous system.
How does the nervous system work together to allow someone to respond to its environment?
The nervous system, muscles, glands (endocrine system), the heart, lungs and the digestive system all work together as a whole. Without the nervous system none of this would be possible.
How the endocrine system and nervous system work together when the body is under stress?
the endocrine and the nervous systems work together to maintain homeostasis
