The sympathetic nervous system is also known as the fight or flight system.
The sympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response.
Yes, the sympathetic nervous system causes vasoconstriction by activating alpha-adrenergic receptors on blood vessels. This response helps regulate blood pressure and redirect blood flow to vital organs during fight-or-flight situations.
The digestive system needs other body systems to provide oxygen and fight off infections. Alone, the digestive system would simply not function and die.
During the fight or flight response, the sympathetic nervous system activates to increase breathing rate and expand the airways in the lungs. This allows more oxygen to be taken in and circulated throughout the body to prepare for the physical demands of the stressful situation.
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.
Over the course of the day, everyone swallows air. A lot of the air, mostly oxygen, is absorbed as it passes through the digestive system. When you are nervous, your body diverts blood away from the digestive system and passes it to the muscles, ready for the 'fight or flight' mechanism. When this happens, the digestive system is less active, so absorbs less of the air in your system. The increased farting is due to the increased volume of oxygen that is not absorbed

The fight-or-flight response is controlled by the sympathetic nervous system, which prepares the body for action by increasing heart rate, dilating airways, and releasing stress hormones like adrenaline. This response helps the body to either confront a threat (fight) or flee from it (flight) in order to ensure survival.
The sympathetic division of the autonomic nervous system is responsible for preparing you body for the fight or flight response. The role of the hypothalamus.Combination of the brain and nervous as well as muscular and cardiovascular system. The brain initiates the process and everything becomes innate from there...the nervous system delivers the fight or flight signals, the heart beats faster and the muscles tense in order to release energy and react quicker to the organism's surroundings Adrenaline prepares your body for the fight response.
