Human Digestive System

The human body is a kind of machine with multiple organs that keep it working efficiently. The energy source of this unique machine is the food we take, and it becomes crucial to manage every organ of the body. The food we take completes a journey within the body that starts from the entering part of the body and ends at the anus.

The digestion system consists of multiple organs that work in a team and break down the food to the energy. The digestive system has multiple organs that help food break down into simple compounds and convert them into energy.

Main Elements of the Human Digestive System Parts and Functions

We will discuss the 12 elements of the human digestive system that play a crucial role in managing the human body.


The mouth is a crucial organ where food starts its journey. Multiple organs take part in the digestion process, and the mouth is the first part of the human body where food starts moving into the human body.


The tooth is a group of different types of complex organs in the mouth fixed into the jaws. Teeth help humans to catch the food and masticate the food. Chewing is the critical process that converts the food into multiple parts. It breaks down the fare into tiny parts and makes it compatible to swallow into the internal body.

Salivary Glands

Food is something that needs to be ready to enter the inner body part. We cannot swallow raw food, and salivary glands release a liquid named saliva that helps us chew the food to turn it into smaller pieces. The food gets moistened before moving to the Pharynx with the push of the tongue.


This is the part of our mouth that pushes food to the Oesophagus. It is situated behind the mouth and the nostril end, allowing food to pass through it and move into the internal part of the human body.


The esophagus is also known as the food pipe and is a flexible tube that passes to the lungs and stomach. The Oesophagus pushes the food to the stomach through a canal that connects Pharynx and stomach.


The liver is the massive organ of the human body, which is crucial for multiple processes of digestion and human growth. It detoxifies multiple metabolites and helps in the development of the human body. The liver produces bile juice, which allows the stomach and small intestine to absorb essential nutrients from the food.


It is a bag made of muscles, which is the central part of the digestive system. All the food gets stored in the stomach and starts breaking down into simpler substances with the help of other digestive enzymes present in it.


The pancreas is present in the abdominal area of the human body, which acts as a fuel generator for the body cells. The exocrine system of the pancreas helps in the digestion of food, whereas the Endocrine system helps to manage blood sugar.

Small Intestine

The small intestine is a tube-like structure in the human body which is an approximately 10 m long tube that absorbs all the nutrients from the food. Pancreatic juice and bile juice allow it to absorb all the minerals and nutrients from simple food.

Large Intestine

It is a tube present below the small intestine, which absorbs water, minerals, and removes the waste products from the human body.


The large intestine passes the waste products to the rectum that eliminates the stool from the human body.


The anus is the opening from where the waste product is eliminated from the body. The rectum pushes the waste products, and the anus is the pathway that helps waste products to leave the body.

These are the main parts of the human digestive system. Eat healthy food to avoid digestion-related problems. You may also take healthy drinks and nutrition to support regular digestive function, overall wellness, and boost energy levels.
