What is the digestive system of human



Digestive system of human & it function


The digestive system of human energy required for all the processes and activities that take place in our bodies is derived from the foods we ingest. The digestive system of humans allows us to utilize food from such diverse sources as meat from an animal and the roots of a plant, and utilize them as an energy source. 

Whether it is the ability to coordinate the chewing of the food without injuring our tongue and lips or the propulsion of the food from the stomach into the duodenum while releasing the appropriate enzymes, our digestive system allows us to manage the process without much thought and often while performing other tasks.

 How the digestive system of human works or its function 


Digestive system of humans is nourished through the digestive system. In the digestive system, groups of organs work together and convert food into energy, which is essential for all the processes and activities that occur in the human body. 

The digestive process is in the gastrointestinal tract. It is a long, tubular structure that starts with the mouth and ends with the anus. This article deals with those organs that participate in the process of digestion.

Digestive systems that help in digestion are:


Mouth 


Digestion in humans starts with the mouth. The mouth cavity or the buccal cavity contains teeth, tongue and salivary glands. The tooth tastes food in small pieces, chewing and grinding it. 

Therefore, teeth help in physical digestion. The salivary glands found in our mouth form saliva and saliva is found in the food with the help of tongue. 

In human saliva, an enzyme is found, which is called salivary amylase. It digests the starch present in the food for sugar. Therefore, the digestion of starch or carbohydrate begins with the mouth. 

But food remains in the mouth for a very short period of time, therefore, The digestion of food in the mouth remains incomplete.

Esophagus 


A diet consisting of a little digested means, through a hose, is reached in the stomach. The tubes of the food tube are muscles that can turn upside down and spread. 

When a slightly digested food reaches the food pipe, the walls become compressed and spread, and it is called peristaltic movement, and this peristaltic movement sends the food inside the stomach.

Stomach 


The food is brewed in the stomach for about three hours. During this time, the food breaks into small pieces and becomes a semi-solid paste. 

The glands present in the walls of the stomach secrete gastric juice and it contains three substances: hydrochloric acid, pepsin enzyme, and mucus. 

Due to the presence of hydrochloric acid, the food is of acidic nature and the pepsin enzyme initiates The digestion of proteins presents in the food to make very small particles. Therefore, digestion of the protein begins in the stomach.

Small Intestine


The small intestine is a long, thin tube. Whose diameter is 1 inch and is about 10 feet long. It is located on the lower side of the stomach. The food that comes out of the stomach is controlled by 'stomata plexus muscular sphincter muscle.

This muscle sends food in small quantities to the small intestine. Do you know that the small intestine is the largest part of the food pipe? In humans, the small intestine is the place of whole digestion i.e. carbohydrate, protein, and fat.

The small intestine receives two glands secretion: liver and pancreas. The liver secretes the bile. It usually lives in the gall bladder. Bile is alkaline helps in breaking food out of chemicals. It makes the food coming from the stomach acidic to the acid so that the pancreas can work on it. The pancreas is a large leaf-shaped gland that is parallel to the stomach and below it. 

The pancreas secretes the pancreas, which contains digestive enzymes such as pancreas amylase, trypsin, and lipase. Amylase breaks the starch, trypsin digests the proteins and the lipase breaks the chemically broken fat.

The glands present in the walls of the small intestine secrete intestinal juice. Intestinal juices contain many types of enzymes that make complex carbohydrates in glucose, protein in amino acids and full digestion in fatty acids and glycerol to fats.

Large Intestine 


The large intestine is a long, thick tube that is 2.5 inches in diameter and about 5 feet long. It is located on the lower side of the abdomen and is wrapped around the small intestine.


After digestion, the particles of food become small and reach through our small intestine through our blood.

 Blood carries digested and dissolved food to all parts of the body where it is incorporated into the form of a cell. 

Underpants food goes from the small intestine to the large intestine. The walls of the large intestine mostly absorb water from this food and make it solid. 

The last part of the large intestine, called Rectum, stores this unhealthy food for some time and in the end it turns out to be the form of stool from our body.

Pancreas


It is known for the production of insulin with blood sugar regulatory function. Digestive enzymes are secreted by the pancreas, which goes into the small intestine. These enzymes help digestion of fat, protein, and carbohydrate.

Liver 


The livers have many functions, but two of its main function within the digestive system are to make and secrete bile and to cleanse and purify the blood coming from the small intestine containing the nutrients just absorbed. 

Gallbladder 


The gallbladder is a pear-shaped reservoir that sits just under the liver and stores bile. Bile is made in the liver then if it needs to be stored travels to the gallbladder through a channel called the cystic duct. 

During a meal, the gallbladder contracts, sending bile to the small intestine. Once the nutrients have been absorbed and the leftover liquid has passed through the small intestine, what is left of the food you ate is handed over to the large intestine. 

Rectum 


Sigmoid colon opens in the rectum. In which the stool collects. The last part of this is called the anal canal. It opens out by the anal (Anus). The rectum is an 8-inch chamber that connects the colon to the anus.

It is the rectum's job to receive stool from the colon, to let the person know that there is a stool to be evacuated and to hold the stool until evacuation happens. 

Anus


This is a hole by which the stool is discarded. They contain sphincter muscles. By which the control of the opening or opening of the anus punch is controlled. In this, there is an involuntary sphincter on the inner side and voluntary sphincter on the outside.

The anus is the last part of the digestive tract. It is a 2-inch long canal consisting of the pelvic floor muscles and the two anal sphincters (internal and external). The lining of the upper anus is specialized to detect rectal contents. It lets you know whether the contents are liquid, gas, or solid.

Appendix 


They sit at the junction of the small intestine and large intestine. It's a thin tube about four inches long. Normally the appendix sits in the lower right abdomen. 

The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria rebooting the digestive system after diarrheal illnesses. 

Other experts believe the appendix is just a useless remnant from our evolutionary past. The surgical removal of the appendix causes no observable health problem.
