Feedforward is anticipatory in nature. It is your body preparing for something before it occurs.

The classic example is smelling something delicious. Even though you haven't eaten anything yet, your mouth begins to salivate, excreting digestive enzymes, and your stomach begins to produce acid. This way your body doesn't have to quickly react.

Another example is exercise. Your heart rate and breathing rate increase long before your muscles begin to run low on oxygen.

You can almost think of feedforward as a type of preventative measure.
