Now look at this image of reflex action. Reflex actions are automatic responses that happen without thinking. For example, touching something hot—your hand pulls back instantly. You don’t think first, the action just happens. Another example is blinking your eyes when something suddenly comes close. These actions are very important because they protect our body from harm. They are quick, automatic, and life-saving in many situations.
