The digestive system is the group of organs that breaks down food into substances the body can absorb and use, and that removes the unusable remainder as waste. It consists of a long muscular tube, the gastrointestinal tract, running from the mouth to the anus, together with several accessory organs that assist digestion. Its work supplies the body with the nutrients and energy needed to grow, repair tissue and function.

Digestion begins in the mouth, where food is chewed and mixed with saliva, then passes down the oesophagus to the stomach. The stomach stores food and secretes acid and enzymes that begin breaking down proteins, churning the food into a semi-liquid mixture. This passes into the small intestine, where most chemical digestion and nutrient absorption take place. Several accessory organs support this stage: the liver produces bile, the gall bladder stores and releases that bile to help digest fats, and the pancreas supplies digestive enzymes along with substances that regulate blood sugar. The large intestine then absorbs water from the remaining material and forms waste for elimination.

Other structures are commonly studied alongside the digestive organs. The appendix is a small pouch attached to the large intestine, while the urinary system, which filters the blood and removes liquid waste, works in parallel to keep the body's internal environment balanced. Disorders of these organs — such as inflammation, infection or obstruction — are an important part of human anatomy and medicine.

Frequently asked questions

What is the main job of the digestive system?: It breaks food down into nutrients the body can absorb for energy, growth and repair, and it eliminates the parts that cannot be used.
What does the liver do in digestion?: The liver produces bile, which helps break down fats; the bile is stored in the gall bladder and released into the small intestine when needed.
What role does the pancreas play?: The pancreas releases digestive enzymes into the small intestine and also produces hormones, such as insulin, that regulate the level of sugar in the blood.

Digestive system the digestive process is the means by which food taken into our bodies is used to provide us with energy and nutrients needed for growth and renewal, with anything that is not used expelled as waste. All of this takes place in what is known as the 'gastro-intestinal tract'. This starts at the mouth where food enters the body and ends at the anus where waste leaves the body. The total length of the digestive tract is an amazing 9 metres, animation
