In brief: Peristalsis
The stomach and intestines are always moving in a rhythmic process called peristalsis.
These structures are literally squeezing and pushing contents forward. Inside the bowels is air that we swallow while eating and drinking. When the bowel squeezes air forward it makes the noise that you hear as a rumble. In medical terms, this is call borborygmi. Probably one of the most fun words in medicine.
