A hole in the skin caused platelets to rush to the site and release a chemical that releases more platelets. This is an example of a positive feedback mechanism.
When a variable is changed, there is a response that leads to further change in the same direction, which is known as positive feedback.
An illustration can be used to explain positive feedback. Positive feedback aids in the quick creation of a platelet plug in a damaged blood artery when we cut our fingers. Platelets are drawn to the wounded location, and as they accumulate, they each release chemicals that draw additional platelets.
In order to stop excessive blood loss, numerous platelets quickly collect and work together to seal the damaged blood vessel's hole.
Positive feedback mechanisms are demonstrated by the posterior pituitary gland's production of oxytocin during labor. The muscle contractions that force the infant into the delivery canal are induced by oxytocin.
