The digestive system organs in the include the liver, gallbladder, stomach, small intestine and the large intestine.

The role of the Digestive System is to break down the food that we eat into nutrients for our body and waste. It squeezes food through 9 metres of twisting and turning tubes. It starts as soon as you begin to chew, with muscles squeezing and powerful chemicals, breaking the food down into smaller and smaller pieces. The liver, gallbladder and pancreas make and release many of the chemicals. The nutrients are absorbed into the blood and some is stored for energy. The waste matter is disposed as faeces and urine.

The digestive system is a very large system and it takes up space from the mouth all the way down to the pelvis. Different parts of the Digestive system are located in different parts of our body.

No a person could not survive with out the digestive system, because with out it you would not be able to get the nutrients and water that we need!

By making sure they drink plenty of water. Eating healthy foods like Lots of fruit and vegetables to get the nutrients that you need!

Intestines: The small intestine is the part of the gastrointestinal tract (gut) following the stomach and followed by the large intestine, and is where the majority of digestion and absorption of food takes place. Liver: The liver is a vital organ. It’s functions include: A filter for toxins, creates protein for the body and creates other chemicals to help digest the food. The liver is necessary for survival; there is currently no way to replace it. Stomach: The stomach is involved in the second phase of digestion, following chewing. It produces enzymes and strong acids to aid in food digestion, and also churns food (makes it a smooth paste) before sending food to the small intestines. Gallbladder: The gallbladder is a small non-vital organ that aids in the digestive process and stores bile produced in the liver.

The main function for the Digestive System is to break down the food into smaller parts so the body can use them to provide energy!

The Digestive System is very important to the human body because it helps us to digest our food.

There a few things that can go wrong with the Digestive System: 1. Appendicitis: Is when your appendix are inflamed, that is because all the bacteria has gone to your appendix. 2.Galstones: Gallstones are little stones that form in your gallbladder. This is a little pouch that sits right under your liver.

The food stays in the small intestine from 1-4 hours. The food stays in the mouth for about 1 minute. In the stomach the food stays there for 2-4 hours Adults can hold 1.5 litres of food in their stomach. Fibre keeps our digestive system healthy.

We eat around 500KG of food each year! In the human mouth our food is either cooled or warmed to a more reasonable temperature! The esophagus is approximately 25cm
