7 Human Stomach
So, the cow has all of those cool parts of its stomach that help it eat grass.
We don’t eat grass so we don’t need four stomaches, we only get one.
Our stomach is just like the cow’s last stomach. When we eat food it goes to our stomach where it sprays special juices that break food down into tiny pieces.
Since we don’t have the same parts as the cow that’s why your tummy hurts when you eat grass.
