What is feedback mechanism? With example
Answers
An example of positive feedback loop is the onset of contractions in childbirth. When contraction begins, the hormone oxytocin is released into the body to stimulate further contractions. As for the negative feedback loop, an example is the regulation of blood glucose levels.
Negative feedback loops occur in your body through its own internal controller for maintaining temperature, pH, hormone levels, blood sugar and other internal variable levels at homeostasis, which is the optimal internal state at which your body operates best.
Feedback Mechanism is defined as the mechanism by which the timing and the amount of hormone released is regulated by the feedback taken from the substrate present in the blood...
e.g. When the pancreatic cells detect high level of sugar in the blood, they secrete insulin. When the amount of blood-sugar decreases, they stop releasing insulin...
