The rumbles, gurgles and growls you sometimes hear from your abdomen typically are due to normal digestion.
Hunger and appetite are controlled by a complex system of hormone-like substances primarily made by your digestive system. When you haven't eaten for a while, these substances are released and cause a part of your brain called the hypothalamus to "switch on" your desire to eat. A message is then sent to your stomach and intestines. This triggers muscle contractions and the release of acids and other digestive fluids as your body prepares for you to eat — or hopefully eat. The thought, sight or smell of food also can trigger this same response — growling, rumbling and gurgling — from your intestines.
Sometimes, stomach growling or rumbling can be a symptom of an underlying gastrointestinal disorder, for example, irritable bowel syndrome. But in such cases, excessive abdominal noise usually is accompanied by other symptoms such as bloating, cramping, diarrhea or excess gas.

It's probably not your stomach you're hearing, but rather your large intestines. This sound is digested food and gas being pushed along by peristalsis -- wavelike contractions that move along the contents of your digestive system. It's what nurses and doctors are listening for when they put their stethoscopes on your abdomen.

The sound isn't coming from our stomachs however from our intestines. The intestines are compressing and squeezing gases round and that makes the whining, squeaking, and different humorous noises you pay attention.
