All animals need to eat food to get energy to live. But in order to use this food, they have to break it down in a process called digestion. And so, all animals have a group of connected organs called the digestive system.
In humans, the process of digestion begins in the mouth where food is chewed into small pieces by the teeth. The tongue helps by moving these pieces around. These pieces are covered by saliva or spit. The saliva makes the food slippery so that it is easier to swallow. It also helps to break down the food.
Once the food is swallowed, it passes through the pharynx, which is like a gate that sends food into the oesophagus and air into the lungs. The food travels down the esophagus and into the stomach. Once in the stomach the food is mixed with acid and crushed some more.
After spending some time in the stomach, the food is sent into the small intestine where nutrients are absorbed. The liver helps by producing some digestive juices called bile. Next, the remaining food goes into the large intestine where the liquids are absorbed. The remaining food is called waste and it is pushed into the rectum where it waits before leaving the body.
