There is only one organ system that breaks down food. That is the digestive system. However the digestive system uses two processes to break the food down. They are physically and chemically.

The first of the two functions of the digestive system is to break down nutrients. The second function is the absorption of nutrients.
The digestive system comprises two main organ groups: the alimentary canal and the accessory organs. The alimentary canal includes organs such as the mouth, esophagus, stomach, small intestine, large intestine, and anus, through which food passes and is processed. The accessory organs, which include the liver, pancreas, and gallbladder, produce enzymes and substances that aid in digestion but do not directly transport food. Together, these organ groups work to break down food, absorb nutrients, and eliminate waste.
The peripheral nervous system (PNS) is divided into two groups of nerves: sensory nerves, which transmit information from the body to the central nervous system, and motor nerves, which transmit information from the central nervous system to the muscles and glands to produce a response.
To break food down and eliminate unneeded waste
Even though there are many systems in the body the only system that is used to break down food is the digestive system. The stomach and the intestines work together to help break down food as well.
Carolus Linnaeus developed the first widely accepted system of biological classification. He classified organisms into two groups - plants and animals - based on their physical characteristics.
