Importance Of Human Body Digestive System 

It is a very important system of the human body as our body need energy to do work and this energy can be obtained by the appropriate food we eat and liquids we drink. When we eat or drink this food enters our digestive system, then digestive system absorbs all the nutrients, minerals, vitamins, irons, carbohydrates, and calcium from this food. After absorbing it, it supplies these nutrients to our body or bloodstream. In this way human body gets energy for all his activities with the help of digestive system. Digestive systems also excrete all the waste of the human body which is very important too.


The digestive system of the human body starts from our mouth and ends at anus. In the way all the parts of digestive tract break the food and move it down of the system. After absorbing all the nutrients in the way, the waste is excreted from the human body. All the process of digestion is controlled by the nerves and hormones of human body.

Components and their Function in Digestive Tract

Mouth and Oral parts

The very first part of the digestive tract is a mouth. Food starts to digest when it enters the mouth. Firstly, the food is crushed by a mechanical process through our teeth.

Salivary Glands and Sliva

There are approximately 1000 salivary glands present in our mouth. As soon as our tongue tastes the food the sensors active the salivary glands to secrete saliva which soothes the food into a bolus.

After that, the food is moved down in digestive tract by means of our tongue. The food is further moved is moved down as we swallow. Here epiglottis is present which helps the food to move down easily and prevent choking. After this food reaches the esophagus.


After you start swallowing esophagus gets the signal from your brain and starts peristalsis and through peristalsis, food moves down to stomach.


When the food or liquid enters the stomach, it is mixed with digestive chemicals or enzymes. Digestive juices added with food with the help of stomach muscles. With these muscles the food is turned into chyme or a thick liquid which is then move to the small intestine.


The pancreas is an organ that produces enzymes that break down the food into fragments of vitamins, minerals, carbohydrates, and iron in the small intestine. These enzymes reach the small intestine by means of tiny tubes known as ducts.

Liver and Gallbladder

The liver produces bile which is a key juice to digest some vitamins. This bile is stored in the gallbladder. Bile is squeezed by the liver and by gallbladder to the small intestine of human body by means of bile ducts.

Small Intestine

When the food reaches in the small intestine, digestive juice is added t to food with the pancreas juice as well as bile from the liver and gallbladder. These juices break down the food into nutrients, fats, and carbohydrates. The muscles of the small intestine absorb these nutrients alongside water and then these minerals and vitamins are then added to the bloodstream or where they are required. After all the required nutrients are absorbed the waste of the food is moved from small intestine to large intestine.

Large Intestine

More water and the remaining nutrients are absorbed from the food when it reaches into the large intestine. The undigested food parts, unnecessary products during digestion of food, and big parts of food that cannot be digested become the waste of digestion process. After this more water is absorbed from this waste by large intestine, that turns this waste into dung or stool. This stool is stored in rectum, an organ below large intestine and then excreted.

Nerves and Hormones

Nerves and hormones of the human body control all the digestion process. Nerves are connected to brain and give signal to brain when to release the digestive juice or how much quantity should be released. They also control the expansion and contraction of muscles that make the food move down in the digestive system. Hormones control the human body by allowing digestive juices at right time and it also signals the brain that you need food or not. Stomach, pancreas, and small intestine release hormones that are very necessary for the digestive system of hum
