1. Blood sugar levels vary throughout the day. Insulin and glucagon help to keep these levels normal. When the body does not convert enough glucose for use, the blood sugar levels in the body remain high. Insulin helps the body absorb glucose, lowering blood sugar and providing cells with the energy they need. When blood sugar is too low, the pancreas releases glucagon. Glucagon forces the liver to release stored glucose, which thus causes blood sugar to rise. (COMER)

This week pick a scenario or situation that illustrates either a sympathetic or parasympathetic response. Explain what happens to the body during this situation and how the body will respond to return to homeostasis.
1. Vasovagal syncope happens when you faint due to certain emotion triggers. A common example of this is when people faint from seeing blood. This happens because your heart rate and blood pressure rapidly decrease, causing you to faint. Aside from potentially hurting yourself from falling, the actual process of fainting is usually harmless.
Before you faint, you may experience going very pale and breaking out into a cold sweat. Nausea also is very common during this process. If the stimulus is not removed these early symptoms typically progress into actually fainting. The person effected is usually only unconscious for a few minutes at most.
The reason for this happening is that the nervous system malfunctions due to the trigger and causes your heart rate to lower. Ultimately this leads to blood leaving your head and causing you to faint. A way to stop this from happening would be to lay down. This prevents blood from not being able to reach your brain and helps potentially to stop this.After a short time, regardless if you faint or not, the body will eventually regulate itself and begin to get your heart rate back to a normal rate, fixing this issue.

One symptom that occurs with the flight or fight response in the dilation of bronchioles. According to Amerman this is caused by norepinephrine binding to the B2 receptors on the cells relaxing them. (Pg 526). This allows the body to increase the volume of air that it can hold. Bronchodilation is a is a sympathetic response that occurs to allow the body the increase air flow for the ability to stay and fight or run. Brochodilation also occurs when exercising and the body returns to homeostasis. The body will return to its homeostasis once norepinephrine is no longer being released allowing the bronchioles to constrict to its normal size.(MARTINEZ)
