Real Question:

Answer 1

Answer:

When you are hungry your brain signals your digestive system to prepare for food. This leads to stomach growling. Your brain does this because it knows that you are hungry, and consequently the brain signals the digestive muscles  to contract. There is also, usually, some gas in the intestines and stomach. The noises come out when the mixture of the gas and fluid, digestive juices, squirt through a opening that separates the stomach and small intestine.

Sometimes the noises happen because of an excessive amount of gas in the small intestine.
