Difference Between Positive Feedback and Negative Feedback

Regarding biological mechanisms, positive and negative feedback are known products of molecular and physiological processes. Both are control systems that are involved in the body’s homeostasis or the propensity of organisms to maintain balance and regulate their internal environment. Without these feedbacks, an organism would lose its capacity to self-regulate. Basically, positive feedback amplifies the original stimulus while negative feedback slows it down. The following concepts expound on their differences.

 

Difference Between Positive Feedback and Negative Feedback

What is Positive Feedback?

In positive feedback, there is a direct positive correlation between the concentration and the process rate. One good example is how the endocrine system regulates the release of its hormones. Particularly, oxytocin is a hormone released by the pituitary gland during child birth. It is crucial in labor and normal delivery. As the contractions increase, more oxytocin is being produced until the child is born. Also, this chemical has been associated with social bonding. For instance, hugging someone stimulates the release of oxytocin. Someone who gets (and gives) lots of hugs also experiences an enhanced production of the said hormone.
