What are the main functions of the sympathetic nervous system

Dilation of bronchi, contraction of heart and sudden decreases in the number of rbc in the blood d.The central nervous system (cns) and the peripheral nervous system (pns).the central nervous system is made up of the brain, the spinal cord, and the retina and controls essentially all the functions that keep you alive and allow you to experience life.The sympathetic nervous system typically functions in actions requiring quick responses.This can include actions of running, fighting, hiding, and generally, actions used to escape predators.The sympathetic autonomic nervous system.

The functions of sns are as follows:Efferent messages can trigger changes in different parts of the body simultaneously.Dilation of the pupils secretion of sweat glands dilated muscles increased alertness slowing down or stopping digestion relaxation of the bladderSympathetic nervous system, division of the nervous system that functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.It works in close association with other parts of the autonomous nervous system, i.e., parasympathetic nervous system.

We can say that it is the sympathetic nervous system through which a person is able to respond to danger and save himself.By contrast, the parasympathetic system controls actions related to feeding and breeding.To allow increased airflow via the lungs, bronchodilation, and less pulmonary secretions happen.The sympathetic nervous system is a division of the nervous system that is responsible for forming localised adjustments (such as sweating in response to a rise in temperature) and reflexing cardiovascular system adjustments.
