Why does your stomach rumble?

Human body

Your body needs food to keep it working. But before it can use the food, it breaks it into tiny pieces, which seep into your

blood. This is called digestion.

MouthIn your mouth, your teeth chop up and chew your food. Your spit helps to break food down and makes it easy

to swallow. When you swallow,

your food goes down a tube

in your throat and into

your stomach.

StomachYour stomach is like a stretchy bag that fills with food. Inside, your food is churned up and mixed with stomach juices. They break your food down into a thick soup-like mixture.
