1 liver- The liver is an organ only found in vertebrates which detoxifies various metabolites, synthesizes proteins and produces biochemicals necessary for digestion and growth. In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm
2 stomach -The stomach coats the food with a mixture of acid and digestive enzymes to help break the food down further. A layer of mucous protects the stomach lining from being damaged by the acid.
The bottom of the stomach is able to contract, which helps to speed up the process. When the food is broken down sufficiently the stomach releases its contents into the duodenum.
3 small intestine = The small intestine is categorised in three parts; the duodenum being the first, the jejunum second and the ileum the final part.
When food enters the duodenum, the pancreas releases enzymes to help break down fat, protein and carbohydrate The gall bladder releases bile, which has been produced by the liver, to help further break fats down into a form that can be absorbed by the intestines.
(LARGE INTESTINE)
The final stage of the digestive system is the colon (large intestine) which absorbs water and salts before the remains are passed out of the rectum as faeces. The colon can also help to absorb remaining carbohydrate and some fats.
