ok, so something goes wrong in the body, lets say you have a temperature. many organs try to help. the body keeps heating up though.
keep in mind that positive feedback is when the body its self pushes levels out of range.
so the fact that the body is heating itself up, pushing the levels out of range, it becomes a positive feedback instead of a negative feedback.
the reason it is harmful positive feedback is that, with all the organs pushing the levels out of range, the body temperature just keeps going up, which of course, is harmful.
Positive feedback works by increasing the effects it causes. There are only a few cases when this is beneficial. An example of one that would be harmful is a rising body temperature. A very high body temperature would cause the body to shut down and the cells to die.
positive feed back can b harmful sometime
for example
. when person has high fever
. it causes a metabollic change that can push the fever higher and higher -
. in some rare cases ;
. the body temperature reaches 113 'F -
. the proteins stop working and metabolisms stops -
. this may be cause death of the person
.
it puts the body in an unstable state
Positive and negative feedback
no
positive feedback - increase activity negative feedback - decrease activity
Negative feedback mechanisms work to prevent sudden severe changes within the body.
A: POSITIVE feedback will force the amplifier to sit at its rail saturated
positive feedback mechanisms
There are two types of feedback mechanisms: positive feedback, which amplifies processes, and negative feedback, which stabilizes systems. For More Information : agilityportal.io
positive feedback mechanisms
Positive and negative feedback
they are positive feedback and increase activity negative feedback.
no
That's negative feedback. Positive feedback ruins homeostasis.
positive feedback - increase activity negative feedback - decrease activity
Negative. There are VERY few positive feedback mechanisms in the body- the only one i know about is birth. Think of negative feedback and positive as a line.
both negative and positive feedback
two include water levels and body temperature
The endocrine system has four major mechanisms of control that regulate its functions. They are: Hormonal control, neural control, negative feedback, and positive feedback.
