1. The Parasympathetic Nervous System will handle my body’s after-dinner service—rest-and-digest. The organs that they control include some organs in the digestive system like bladder and stomach; these organs are supplied by the vagus nerve.. It secretes digestive enzymes in the stomach and intestine to help digest food. Moreover, release bile to help in digestion.
2. My friend experienced the “flight or fight” response, which is caused by the sympathetic nervous system. Some noticeable effects are an increase in heart rate, hair erection, and increased sweating. These effects or reactions are to help my friend in reacting in dangerous situations. Basically, it increases the awareness of my friend so that he or she can react properly and promptly to the bicycle not only for his or her safety and the bicycle rider's safety.
