group-discussion.jpgLet's examine another scenario and see if we can uncover what sort of feedback loop is in play here.  Note that this will be a very common and relatable scenario, but it's one that students in the past have found quite tricky in terms of its feedback loop characteristics!

Consider the prompt below and compose a post with your response.  You will receive 1 point for submitting a post of your own (3 sentences or more), after which you will be able to see your colleagues' posts.

 

Discussion Prompt:

Fever is one of the most common symptoms of coronavirus.  Most of you have likely had fevers before!  For example, during a fever, your body might maintain a high temperature (e.g., 101°F) for a few days.

During a fever, when your body is maintaining 101°F, is your body temperature in a negative or positive feedback loop?  How can you tell?

    I believe your body is in a positive feedback loop. I say this because we are starting with a fever and ending with a fever. if it was a negative feedback loop, then we would end with no fever.

    it is a positive feed back because its self reinforcing mechanisms the initial signal.which makes it a posotive feed back due to the facts that it is doing more and amplifying the body temperature.

    Your body would be in a negative feedback loop because you’re not getting any better. The only way it would be considered a positive feedback loop would be if you got better. Also your body could potentially be a positive feedback loop if you’re body was trying to fight the illness.

    The body is in a positive feedback loop in this scenario. This is because when sick, in this case, the body temperature rises but doesn't seem to drop back down to a regular temperature. If the body were in a negative feedback loop, the body temperature would drop back to homeostasis.

    I think this fever is an example of a negative feedback loop. Since the body is maintaining a high temperature, it stays close to/at the set point. The body keeps the temperature close to the set point making it a negative feedback loop.

    I believe it is Negative feedback because normally your body temperature is not high but during a fever your temperature rises. I use the arrow method and got negative feedback. I believe the question can get interpreted differently if you have the fever and the temperature stays the same it would be positive feedback.

    I would say the body is in a positive feedback loop considering the body is maintaining a high temperature rather than reducing. During a negative feedback loop, the body would be regulating body temp back to normal. However in this case, it’s displaying a temperature that is above normal.

    When your body is maintaining a 101 degrees fever, your body temperature is in a positive feedback loop. I believe it's in a positive feedback loop because I noticed that the example used the word "maintaining" which means that the fever is not getting any better. Instead the body continues to remain at a high temperature for several days. Though the body may be working to fight against the fever, in this example no changes opposite to the deviation seem to be resulting which is why I wouldn't label this a negative feedback loop.

    I think the body is in a positive loop. The stimulus is a high temperature. The fact that the body temperature is staying the same or maintaining denotes a positive loop feedback.

    I believe that the this example is a negative feedback loop. I think the body is just creating a new set point for the body temperature as it fights off the virus. Since your body maintains 101 degrees then your body is going against the deviation to lower. the body temperature.

    I think that during a fever, when your body is maintaining 101 degrees that your body temperature is in a negative feedback loop. This is because in a positive feedback loop, the body is increasing its temperature. However, the negative feedback loop is maintaining the body's temperature at 101. This is because in a negative feedback loop the result of a reaction is reduced to bring the system back to a stable state. In general, if a fever reaches 103-105, it is considered to be dangerous, but since the body can keep the fever at a safe level and still be high enough for it to fight off any infections is it being maintained.

    I think that this is a positive feedback loop because if it is initially a high temperature and has not decreased, then the temperature is just being amplified.

    this is an example of a positive feedback loop because when your body detects an infection it increases your bodies temp.

    During a fever you're body temperature Is in a positive feedback loop. It's positive feedback because its not going the opposite direction to a lower body temperature which would make it a negative feedback . Maintaining a high fever is going the same direction as the deviation .

    I believe that an increased body temperature from a fever is an example of a negative feedback loop. I think this because the increased temperature is a reaction from the body trying fight an infection. The way I went about this thought process is similar to what we did in class with the up and down arrow. The body senses an "increase" in infection and ups the body temperature to "decrease" the infection. Once the infection is gone you will typically break the fever and your body temperature will go back to normal.

    During a fever when your body is maintaining 101°F; your body temperature is in a positive feedback loop as it is maintaining 101°F rather than going back to the set point when the body is trying to reduce the fever. The average body temperature is 98.6°F and the fever rises to 101°F while also maintaining at that temperature. For it to be considered as a negative feedback loop, the body temperature must decrease to the set point. However, that is not the case with the body continues to stay at 101°F, which makes it a positive feedback loop as it does not go back to the set point.

    A fever of 101 degrees for a few days is considered a negative feedback loop. This is your bodies way of fighting off the pathogen in order to get your body back into homeostasis. You can tell because your cell receptors detect a pathogen has entered the body and a fever acts as the effector. Generally speaking fever's at 101 degrees isn't necessarily a bad thing, this is why medical professionals will typically tell you to stay home and rest. Some also believe that our white bloods cells work better in the raised body temperature.

     

    Now, if the fever never went back down to the normal set point after a few days or if the fever increased then this would be an example of positive feedback loop.

    This is a negative feedback loop because it is at an equilibrium point. If you take a fever-reducing medication, the fever will return after the drug wears off because your body is actively maintaining that temperature. Therefore, this is an example of negative feedback.

    When having a fever of 101°F for a few days I would say this is a positive feedback loop. This is a positive feedback loop because the fever is being maintaining at that temperature but it isn't going back to the original set point. Positive feedback is known for things to be moved further away from the set point like staying above, below or the same but away from the set point.

    During a fever, when our body is maintaining 101°F, our body temperature is in a negative feedback loop. This is because the temperature control is a negative feedback mechanism that it is to help fight off an infection or the fever itself to which the body heat is lost to environment then it drops down to normal body temperature.

    During a fever, when your body is maintaining 101°F fever your body would be in a negative feedback loop. You can tell it's in an negative feedback loop because the body's initial stimulus is a 101°F fever and if the response is still at a 101°F fever, there was no counteracting response to the initial stimulus. Thus, since they are the same it is still considered a negative feedback loop, even if the fever temperature isn't decreasing.

    I believe the body temperature is in a negative feedback loop. I can tell because the body is maintaining a high temperature rather than letting the temperature exceed normal limits. Although a temperature of 101°F+ is not normal, the body is fighting off the infection and not allowing it to become worse therefore maintaining stability.

    It is typically in a positive feedback loop. In a positive feedback loop, the response reinforces and amplifies the stimulus, leading to an increase in the original disturbance. In the case of a fever, the elevated body temperature is the stimulus. As the body detects an infection or other factors triggering the fever, it initiates a response to increase the body temperature. The higher temperature creates an environment less favorable for the growth of certain pathogens, contributing to the body's defense mechanisms. The positive feedback loop continues until the body successfully fights off the infection or the external factors causing the fever. Once the trigger is resolved, the body returns to its normal temperature through various mechanisms, such as sweating and increased blood flow to dissipate heat.

    During a fever, I believe for our body to maintain 101 °F is in a positive feedback loop. That is because it is a deviation from normal range to a definite end point. And that is because the high temperature is a response that your body is fighting off the virus.

    In my opinion, the body temperature is in a positive feedback loop because fever increases body temperature to 101 'F. The body's defense mechanism can not maintain to normal body temperature at 98.6'F. That result shows the direct proportion of fever and higher body temperature .

    During our lecture class, we did group work on the Coronavirus feedback loop. We also understood that macrophages, which operate as receptors and control centers, and T-cells, which act as effectors, collaborate to keep the body in homeostasis. When our body comes into contact with a virus, specifically Coronavirus, it responds by raising its temperature. We  have a fever because our body is attempting to eliminate the virus or bacteria that caused the infection. Most of these bacteria and viruses thrive when our body temperature is normal. However, having a fever makes it tougher for them to live.Therefore, Fever is an example of a negative feedback loop.

    During a fever, my body temperature is in a positive feedback loop, which means it's increasing to fight an infection. The elevated temperature triggers more responses to boost the fight against the infection. It's like my body's way of turning up the heat to help get rid of the intruders.

    This situation shows a negative feedback loop. The reason for that is because during covid, if you were to get a fever, it will maintain at a high temperature for a few days. After those few days have passed, then it will go down to a normal temperature. You start off with a high temperature and end with a normal temperature.

    During a fever when a bosy is maintaing itself at 101 degrees F, the body is in a positive feedback loop. The definition of a Positive feedback loop is when the body deviates further from the set point which in this case is normal body tempt of 96 to 98. The body is pushing the effectors extra hard to bring the body back to it's regular set point.

    In this example, I believe the body temperature is a negative feedback loop. Since the example says the body is maintaining a temperature of 101°F, that may mean that 101°F is the set point in this case. The body will try to reverse that change to go back to normal levels.

    when someone was contracted corona virus the patient presented symptom that having fever high temperature. When the temperature elevated releasing chemical signal reported to the brain causing the body to generate more heat. In my point of view elevated body temperature is called negative loop.
