Food  is broken down by our digestive system and transported to every part of our body by our circulatory system. The main part of the digestive system is the digestive tract. This is like a long tubethat starts at the mouthand finishes at the anus, where  wastes leave the body Mouth Teeth bite off and chew food . Chewing mixes the food with saliva. Oesophagus The oesophageus, or gullet, is a muscular tube. It takes food from the throat and pushes it down through the neck, and into the stomach. Stomach The stomach has thick musclesthat contract to blend the food  in its wall. The stomach lining produces strong digestive juices. that  breakedown nutrients. Pancreas The pancreas, makes digestive juices called enzymes which help to digest food fbefore it enters the small intestines. Gall Bladder This small baglike part is tucked under the liver. It stores a fluid called bile that helps to digest fatty foods. Small Intestines It is about 20 feet long.  Enzymes digest  food until the nutrients are small enough to pass through the lining of the small intestine, and into the blood. T Liver Blood from the intestines flows to the liver, carrying nutrients, vitamins and minerals, and other products from digestion. The liverstores some nutrients, changes them from one form to another, and releases them into the blood acccording to the activities and needs of the body. Large Intestine such as Spare water and body minerals, are returned through the walls of the large intestine, back into the blood.
