Parasympathetic and Sympathetic refers to two branches of the Autonomic Nervous System (ANS).
<span>The Parasympathetic Nervous System (PNS) has a general function of controlling bodily functions such as homeostasis and the body's response during rest. </span> <span>The Sympathetic Nervous System (SNS) on the other hand refers to the body's response to perceived danger. </span> Each of these result in different bodily responses. In the case of the PNS these include: a decreased heart rate, bronchial tube constriction, relaxation of muscles and the constriction of th pupils. When it comes to the SNS, these responses include: increased cardiovascular contraction (leading to an increased heart rate), dilation of the bronchial tubes, contraction of muscles and dilation of the pupils/
The scientific method may not follow the exact same steps each time because experiments are different. Some may have many more steps to follow to reach the conclusion, while others may take less time and have less steps. For example, some experiments may require a chart or graph of the results to be made, while others do not need that to display the results
