Coffee contains caffeine, along many other kinds of beverages. Caffeine is a psychoactive drug, meaning that its crosses the blood-brain barrier and acts primarily on the central nervous system. Caffeine stimulates the cortex of your brain, thus heightening the intensity of mental activity. This can result in a temporary feeling of alertness and, in the short term, banishes drowsiness and feelings of fatigue.
In short, caffeine from coffee travels through the blood stream to the brain where it stimulates the central nervous system temporarily, thus making one feel more alert.
