What logical reason explains why the sympathetic nervous system slows down blood flow to the digestive system?
Vasocontriction throughout the intestinal tract during sympathetic discharge helps redistribute the blood and makes it easier for the heart to maintain higher diastolic blood pressure. This increases blood flow to major muscle groups and in turn permits increased oxygenation and energy utilisation, both of which are necessary during situations where physical exertion may have a (perceived) survival benefit.

Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
What other body system is directly connected to the sympathetic nervous system?
The sympathetic nervous system is directly connected to the cardiovascular system. Activation of the sympathetic nervous system leads to an increase in heart rate, stronger heart contractions, and constriction of blood vessels, helping to prepare the body for fight or flight responses.
What are the two nervous systems?
parasympathetic and sympathetic nervous systems
How might you feel when your sympathetic nervous system is simulated?
With current technology it is not yet possible to simulate a sympathetic nervous system
Based on the main neurotransmitters the sympathetic nervous system can be classified as what?
The sympathetic nervous system can be classified as adrenergic, based on the main neurotransmitters used.
What nervous system increases most body systems except digestive and urinary systems?
The sympathetic division of your autonomic nervous system (ANS) increases the activity of most bodily systems excepting the digestive and urinary. The layman's term for the sympathetic nervous system is the "fight-or-flight" nervous system. The parasympathetic nervous system is the other division of the ANS and is termed the "rest and digest" nervous system.
Are the digestive tract and heart enervated by the sympathetic nervous system?
Digestive system has got own local nervous system in the form of myenteric plexus. But then it is supplied by vagus nerve, the tenth cranial nerve, that comes down all the way from your skull. It has got powerful influence on your digestive system. Only terminal part of digestive system gets it's parasympathetic nervous supply from the sacral autonomic outflow.
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.
What component of the nervous system is associated with the fight or flight?
sympathetic nervous system.
Is sympathetic active after you have eaten a meal?
Unless some other factor (e.g., a bear trying to attack you) activates your sympathetic nervous system, the parasympathetic, not the sympathetic, nervous system is active after eating. Parasympathetic activation results in a decline of the stress hormones epinephrine and norepinephrine, which allows blood to be directed towards the digestive system so that digestion and absorption of nutrients can occur. When the sympathetic nervous system is activated, blood is diverted from the "non-essential" organs, such as the digestive system, and towards the heart, brain, and muscles.
What is the celiac ganglion?
The celiac ganglion is part of the prevertrebral ganglions. It is the ganglion that is part of the sympathetic nervous system that innervates the digestive system.
What other body system is directly connected to the sympathetic nervous system?
The sympathetic nervous system is directly connected to the cardiovascular system. Activation of the sympathetic nervous system leads to an increase in heart rate, stronger heart contractions, and constriction of blood vessels, helping to prepare the body for fight or flight responses.
What nervous system gets your body ready for action in an emergency by increasing adrenalin and slowing down digestion.?
sympathetic division of the autonomic nervous system
Sympathetic and parasympathetic nervous system's are subdivisions of what nervous system?
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.
What activates the sympathetic nervous system?
epinephrine and norepinephrine stimulate the sympathetic nervous system
What components of the nervous system is associated with the fight or flight response?
sympathetic nervous system.
What hormone activated the sympathetic nervous system?
epinephrine and norepinephrine stimulate the sympathetic nervous system
