The food that we eat makes an incredible journey through our body from the upper portion (our mouth)

to the lower portion (our anus). Along the way the beneficial part of the food (nutrients) is absorbed which gives us energy. Our digestive system is made up of the gastrointestinal tract and liver, pancreas, and gallbladder. The gastrointestinal tract is also called the GI tract. The GI tract consists of different organs which are hollow and connect each other from the mouth to the anus. The organs in the order in which they are connected from the mouth to the anus are the mouth, esophagus, stomach, small intestine, large intestine, and anus. There are many functions of the digestive system that we will talk about later in the article.

The digestive system is made in such a way that it can do its job of turning food into nutrients and energy for us. After absorbing the useful parts of the food, it filters the unnecessary part of it which is solid waste, or stool for disposal so that we can have a good bowel movement. 

Functions of the Digestive System

The functions of the digestive system with diagram are as follows:

• Motility and Locomotion

The food that we eat moves through the digestive tract, the process is known as peristalsis. It is the movement of the GI tract that further moves the food through the digestive system.

• Secretion

Secretion is the process of releasing hormones, enzymes, and other substances which can help the body in digesting food. The hormones usually tell the body when to produce digestive juices and it even sends signals to the brain when you are hungry or full.

• Digestion

This is one of the basic functions of the digestive system. The ingested nutrients such as proteins, carbohydrates, minerals, fats, and water are reduced into smaller particles that are smaller enough to pass through the lining of the gut and then enter the bloodstream. The digestive system breaks down the foods that we consume so that we can use them for energy, growth of our body, repair of the cells. The proteins break down into amino acids, the carbohydrates break down into simple sugar and the fats of our body break down into fatty acids and glycerol, 

• Absorption

The digested nutrients pass from the gut into the lymph system so that it can pass the nutrients to the rest of the body. The lymph system carries vitamins and fatty acids, while the blood carries simple sugars, amino acids, glycerol, and some vitamins and salts to the liver.

• Defection

Defection, which is also known as bowel movement, is the process of eliminating the solid wastes, stools from the body.

Conditions that Can Affect the Functions of the Digestive   System

Many health conditions can affect the functions of the digestive system. The conditions might be temporary, long-term, or chronic. Some basic conditions are mild and are not that dangerous but if you are suffering from a serious digestive issue medical attention is very much needed.

2. Constipation- Constipation is a condition when you poop less than usual and your poop is dry and hard and it becomes pretty difficult and painful for the poop to pass.
3. Gallstones- Gallstones are usually small pieces of solid material that are formed by digestive liquids, and it forms in your gallbladder (a small organ under the liver).
4. Cancer- Cancers that can affect tissues and organs in the digestive system are known as gastrointestinal cancer. The most common digestive system cancer is liver cancer, pancreatic cancer, rectum cancer.
