Talking about the digestive organs and their functions in humans, it is actually necessary to know. Because this organ is a supporter of human life.
Don't let the wrong lifestyle cause this organ to be disturbed and get sick. Therefore we must maintain the health of these internal organs in order to function normally.
The digestive organs are a complex mechanical circuit. Imagine from the form of a solid mass then chewed until smooth and then swallowed. It is in the stomach that the actual functioning of the digestive organs begins.
The food is then processed with the help of enzymes, then substances that are good for the body such as nutrients, carbohydrates, proteins are used to support the body's performance, while the rest is discarded.
Overview of the Digestive Organs and Human Functions
Each digestive organ has several parts, each of which has its own function. The following is a series of digestive organs and their functions in order from the top first:
1. Mouth
One of the organs and their functions starts from the mouth. This organ is the front door of the digestive system of humans and animals. The mouth is the place to enter food and drink into the stomach.
This organ contains several supporting organs such as the tongue, teeth and saliva. Teeth function to crush food that is put in the mouth.
Normal humans consist of incisors located in front, the function of these teeth is to slice and slice food.
The molars are located behind themselves, their function is to smooth the food until it is soft. While the canines are used to tear food, there are four, two above, two below.
The function of the tongue is as a sense of taste for food, with the tongue we can distinguish tastes such as sweet, bitter, sour and bland, from this tongue we can judge the taste of food.
The tongue also functions as a tool to regulate food when chewed so that everything can be mashed. When eating humans have to chew food up to 34 times so that all the food becomes smooth.
The oral cavity also secretes saliva which aims to keep the mouth moist. In addition, saliva is responsible for digesting foods that contain carbohydrates into disaccharides.
2. Esophagus
This organ is commonly called the esophagus while the Latin name is the oesophagus. Shaped like a tube, the esophagus connects the mouth to the stomach, and functions as a channel for food that is swallowed and then falls into the stomach. The length of the esophagus is very relative depending on human age.
The esophagus is different in function from the windpipe or trachea. The throat is part of the respiratory organ / respiration.
Indeed, it is located close together, but the two long organs are separated by a kind of valve called the pharynx which is located at the base of the neck. The function of this valve regulates food to enter the esophagus.
Thanks to the peristaltic movement of the esophagus, the flow of this mashed food moves smoothly towards the stomach. In addition, assistance from drinking water, which serves to facilitate the movement of food.
3. Stomach
The next organ is the stomach, its shape is like an elongated bag. The stomach is a place to accommodate refined food. Actually the stomach is a muscle that has space, whose name is a muscle that can move when given a stimulus.
The stomach has three chambers, each of which has a different function. The first chamber is the cardia, the vestibule where food enters from the esophagus.
The second room is the fundus which functions as a place for food processing, and the last room, the antrum, is in the back room where the products of food processing are distributed in the duodenum.
This stomach functions to digest and mix the food with hydrochloric acid, and break down the food into nutrients. Like breaking down protein into peptones.
4. Small intestine
The small intestine or scientific term small intestine, the place is between the stomach and the duodenum. The length of this intestine can reach 6 meters if stretched.
In the small intestine, chemical digestion occurs with the help of enzymes. The intestine consists of three parts, namely the duodenum, the absorption intestine and the empty intestine.
5. The duodenum
The duodenum, is the fifth digestive organ in the series of the human digestive system. Small in shape and short in size, the location of this intestine is close to the stomach because it is still part of the small intestine.
The function of the duodenum is to distribute food to the small intestine. In addition, there is still an empty intestine and intestinal absorption system work is a chemical process and the distribution of food enzymes.
6. The Large intestine is the last channel in the human digestive system.
The large intestine consists of four parts, namely the right ascending colon, left ascending colon, transverse colon, and sigmoid colon. This organ is in charge of accommodating the remnants or dregs of the digestive process. Then, ensure the balance of body fluids or electrolytes, and retain water.
In the large intestine there are good bacteria that are in charge of degrading bacteria and bad substances. Eat it if we suddenly have a stomach ache and diarrhea is a form of bacterial resistance in the body to get rid of toxins from the stomach.
7. Rectum
The rectum is the last channel to accommodate the remaining liquid food waste to be compacted. When the rectum is full, there is an automatic stimulus to excrete feces.
Health Disorders in the Digestive Organs
After discussing the digestive organs and their functions, the organs may not always run well. There are times when we feel something unpleasant in our stomach, such as heartburn, bloating or even diarrhea.
Most health problems in the digestive organs because of food and unhealthy lifestyle factors.
The following is an explanation of health disorders that attack the digestive organs:
1. Ulcer
Ulcer is a gastric disorder, this disease arises because people eat late. Stomach that is rarely filled with food can cause injury to the stomach wall.
So the stomach is forced to secrete excessive enzymes. If left untreated, this wound will widen and cause severe pain sensations.
Ulcers can also arise due to dietary factors, for example eating too much spicy or sour food. Actually, the stomach is not strong enough to accommodate spicy food, because it can cause the stomach wall to become irritated.
2. Diarrhea
Diarrhea is the process of rejection of the digestive organs against bad bacteria or fungi that enter through food. When the virus enters the body, all the digestive organs of the body become inflamed.
The large intestine continues to work to eliminate diarrheal bacteria by continuing to excrete excessive amounts of fluid.
So, when feces come out of the body in the form of liquid or loose stools. Therefore, diarrhea patients should be given a lot of electrolytes to drink, its function is to restore lost fluids.
In addition, to avoid dehydration. This disease can attack anyone, toddlers, children to the elderly. Dirty living environment and drinking water contaminated with ecoli bacteria.
3. Bloating or flatulence
Flatulence is a digestive disease that often attacks anyone. This disease is caused because the stomach is filled with gas produced from food.
In addition, food residues that fail to be digested by the stomach can also emit gas due to fermentation factors.
There are many types of food and drink that contain high gas such as cabbage, mustard greens, durian, sweet potato. In addition, carbonated drinks, wine, and beer and other types of fermented beverages.
So a little about the digestive organs and their functions, hopefully it can provide enlightenment.
