The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events.
While the sympathetic nervous system is often referred to as the fight-or-flight-part of the body, the parasympathetic nervous system is sometimes called the feed-and-breed system because it regulates more mundane processes that are vital for the maintenance of normal life. The functions of this system include: 1  Regulating digestion, including urination and defecation. 2  Regulating sexual arousal. 3  Slowing the heart rate and lowering the blood pressure after the sympathetic nervous system has activated the fight or flight response.
