How is digestion an example of negative feedback?

Digestion involves negative feedback as the body regulates the release of digestive enzymes and hormones in response to food intake. When food enters the stomach, it stimulates the secretion of gastric juices, which aids in breaking down the food. As digestion progresses and nutrients are absorbed, signals are sent to the brain to reduce the production of these digestive substances, maintaining balance and preventing overproduction. This feedback mechanism ensures that digestion operates efficiently and prevents potential harm from excessive enzyme activity.
