Reflex actions are involuntary responses to stimuli that help organisms quickly adapt to potentially harmful circumstances. They are triggered by a stimulus, such as touching something hot, which elicits an immediate response like pulling one's hand away. A stimulus is any environmental change that causes a reaction in the body, while a response is the reaction produced to a stimulus.
