    It is caused by air being moved around by muscle contractions in your digestive tract. For detailed explanation of this and why your muscles are always busy contracting even when you have no food in there click on the following link :

    I heard that the reason the stomack growls is because since you haven't eaten in a while there is only air in your intestines and so the air is being pushed around trying to find food and the air makes that sound

    your stomach growls because when you have no food in your stomach. your body is eating your stomach liner because there is nothing left. and as it eats the stomach liner it creates acid reflex and air in your stomach. that why your stomach growls

    Actually though the rate and force of peristalsis typically increases in the presence of food, activity also increases after the stomach and small intestines have been empty for approximately two hours. In the latter case, receptors in the walls of the stomach sense the absence of food, causing a reflex generation of waves of electrical activity (migrating myoelectric complexes, or MMCs) in the enteric nervous system. These MMCs travel along the stomach and small intestines and lead to hunger contractions. Such hunger contractions start in the antrum, or lower region, of the stomach and propagate along the entire length of the gut, sweeping to the terminal ileum. They clear out any and all stomach contents including food remnants, bacteria and mucus and keep them from accumulating at any one site.
    So =] that's why your stomach growls when you are hungry.
