Why do people's stomach growl when they are hungry?

Question

Why is it that our stomach "growls"??? Is it that our body is trying to digest food and there's nothing in there, lol? Anyone have the answer or any info. about it?

Thank you!

i don't know if it is because your stomach's empty. mine rumbles n growls completely randomly at any time of day, whether i'm hungry or not.... :S

I think it is caused by movement of food. You can only hear/feel it because your stomach is empty.
