The feedback loop is essentially a chain of cause and effects that occurs continuously (sort of like a loop that continues to go around and around). The army photographer was experiencing a “sweeping adrenal rush, and thought” (Preston 323) but the feedback loops connects to this in way. Cells communicate via signals such as hormones which leads to a domino effect within the cell with proteins which trigger out a response. Adrenaline (or epinephrine) is a common hormone that the body releases as a response from something in the body’s exterior (such as the environment, or an action) or internally. The release of this hormone may cause more adrenaline to be released, causing feedback loop. Adrenaline is really mostly known as the chemical that causes the “flight or fight” response. This hormone performs this as it is responsible for catalyzing the breakdown of glucose usually in the liver. This quick breakdown leads to energy that can be used pretty much instantly during moments which cause it to be released. Pretty much, adrenaline performs by latching to receptors (proteins) of cells that are found on the the cell’s surface. This is a signal which leads a sudden start of the metabolism; this results in a signal that causes the body to suddenly react. The feedback loop will lead to a production of more adrenaline to be released; causing an energy rush.

If adrenaline is produced in large amounts in one time the body reacts in certain ways. The “flight or fight” response refers to a collection of responses produced by the body during stress. In addition to the release of adrenaline, they include: widening of the bronchioles, increased blood flow to the muscles, and reduced blood flow to the intestines. These responses in particular, open up a person's airways allowing more oxygen into their system which allows the heart to pump faster, increases a person’s agility and strength, and sends blood to the brain. These physical changes are supposed to aid in self-preservation, however humans are stressed out about more than life or death situations so these biological responses occur with more frequency in the Human world.

Hi Ricky, can you describe instances when adrenaline is commonly used in our body?
