The first thing is that digestion begins in your mouth.You use your teeth to chew and make your food smaller so you can swallow.These little things called salivary glands produce saliva constantly so you can chemically break down food.You are probably wondering how you taste your food.These little things called are called taste buds and each set can only taste one type of flavor.After the food is broken down your tongue pushes your food down your esophagus.
In the esophagus there is a muscle contraction which pushes the food down into the stomach.In the stomach there is a chemical that breaks down food and it is called hydrochloric acid.The reason the acid can be in your stomach is that your stomach has a layer of mucus that protects your stomach from being burned.
The next part of digestion is the small intestine.The small intestine starts from the stomach.The small intestine can be from thirteen to twenty feet long!Wow that is pretty long.These little things called villi absorb nutrients to get sent to the rest of the body.Once the food gets to the end of the small intestine it is the beginning of the large intestine.
The large intestine starts at the end of the small intestine.The large intestine is 5 feet long!It is shorter than the small intestine but it is wider.The large intestine's main job is to remove water from the waste so you do not get dehydrated.When the food is completely dry it is sent to the rectum.The waste piles up then goes to the anus.When it gets there your in the bathroom.
Here is a video on the process of Digestion.
