Mouth
The opening through which food passes into the body, the part of the face that includes the lips and the opening behind them.
Esophagus
The esophagus is an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach.

In the digestive system, the esophagus pushes food into the stomach by waves of contractions along its muscular walls.
Stomach
Your stomach is at the end of your esophagus. The food is then made into a chyme at a pH of 1-2, then it continues to break down the food chemically now the small intestines can absorb the nutrients and minerals from the food.
Small intestine
The molecules go into the small intestine and are absorbed. The bile and enzymes help break down the food, by the end of that all waste food are digested, in the small intestines.
Large intestines
Water from waste food is absorbed into the large intestine which leaves behind waste called faeces.
Anus
The faeces is then removed from the body by the anus.
