Anatomy of the digestive system and its function; How do the components of the digestive system work?
The anatomy of the digestive system is designed in such a way that the food takes a long journey in your body after passing through the mouth to reach the lower part of the digestive system (anus). During the anatomy of the digestive system, the useful parts of the food are absorbed to supply the body with energy.
The anatomy of the digestive system is one of the largest systems of the body, which is responsible for consuming food, digesting it and absorbing useful substances with its various components.. Follow LLC.

What is the digestive system?
The anatomy of the digestive system, which is the general part from the mouth to the anus, includes a long and twisted hollow digestive tube about seven meters long.. This tube consists of the mouth, pharynx, esophagus, stomach, small intestine, large intestine and rectum..
On the other hand, digestive glands such as salivary glands, glands of the wall of the stomach and intestines, pancreas and liver are the main components of digestive anatomy.... The digestive system has useful bacteria that, in addition to helping nerves, nervous hormones and blood circulation, cause food digestion... Together with the components of the digestive system and blood circulation, these bacteria digest the food and liquids that we eat and drink every day. do.
It is good to know that the anatomy of the digestive system from the mouth to the anus is necessary for digestion, absorption and excretion of food... Therefore, the correct functioning of each part of the digestive system makes this process not a problem.... To ensure the health of your digestive anatomy, you can receive online consultation from a gas specialist, online consultation by phone, SMS or video from a gas specialist.. href="https://gcorp.cc/">GCORP LLC.

Anatomy processes of the digestive system
They are divided into the following steps:
- Swallowing (saliva and mouth enzymes enter the pharynx after combining with food and enter the esophagus from there)
- Contraction (The tube of the digestive system starts mechanical digestion with the help of contractions.)
- Secretions (Endocrine and exocrine glands in the digestive system cause digestion and chemical digestion of food.)
- Digestion (Digestive enzymes in the stomach start the digestion process.)
- Absorption (The process of absorption is carried out through the cells of the small intestine.)
- Excretion (Indigestible food is removed from the last stage of the digestive system anatomy cycle.)
Getting to know the anatomy of the digestive system
The components of the digestive system, in order of their function, include the following:
mouth
The most basic part of the anatomy of the digestive system is the mouth... actually the digestion of food starts through the mouth before starting to eat... salivary glands are activated by seeing and smelling food... then by chewing, the pieces of food are divided into smaller pieces for easy digestion...

Esophagus is located in the throat and near the trachea.... When swallowing food, the esophagus receives it from the mouth.... Before the food enters the trachea, a small epiglottis (tongue above the larynx) is formed on it so that you do not choke when swallowing food.. >
Food enters the stomach with a series of muscle contractions called peristalsis... In order for food to reach the stomach from the esophagus, the ring-shaped muscle (inferior sphincter) at the end of the esophagus must relax... Then it contracts so that the contents of the stomach do not return to the esophagus... Gastrointestinal Diseases
Stomach
Stomach is a hollow bag-like organ that holds food and stomach enzymes inside.... Strong acid and its main enzymes are secreted by the mucous cell of the stomach.... After the digestion process is completed, the contents of the stomach are released into the small intestine.
small intestine
The small intestine is a muscular tube 5 to 6 meters long and is considered the longest part of the digestive system. Since the diameter of this intestine is 2 to 4 cm, it is also called the small intestine.
The small intestine consists of three parts:
- Duodenum (the first part of the small intestine)
- Jejunum (responsible for absorbing nutrients in the bloodstream)
- Ileum (responsible for absorbing nutrients in the bloodstream)
The contents of the small intestine are initially semi-solid and become liquid after the breakdown process is completed... Next, nutrients are absorbed and the remaining liquid passes through the small intestine into the colon or large intestine.

Pancreas
The pancreas is responsible for the secretion of digestive enzymes in the duodenum to break down protein, fat and carbohydrates.... Another function of the pancreas in the anatomy of the digestive system is to secrete insulin to metabolize sugar and enter it into the bloodstream.
Liver
The liver has many responsibilities, but its main role in the anatomy of the digestive system is the processing of nutrients absorbed from the small intestine. In fact, the secretion of bile from the liver and its entry into the intestine causes the digestion of fat and some vitamins. Another function of the liver in the anatomy of the digestive system is harmful..
Gallbladder
Bile stored from the liver is transported by the gallbladder to the duodenum in the small intestine.... In this way, the absorption and digestion of fats is easier.

Colon
The large intestine or colon processes the body's waste materials so that the intestine can be emptied more easily. The length of the colon is about one and a half meters and its diameter is about 6 cm..
The components of the large intestine are:
- Secum
- Ascending colon
- transverse colon
- Descending colon
- Sigmoid colon
The contractile muscles of the intestine excrete feces or waste materials left over from the digestive process first in liquid form and then in solid form. The stool is first stored in the sigmoid colon to be emptied into the rectum with a collective movement once or twice during the day.. It takes about 36 hours for feces to pass through the large intestine.

Rectum
The rectum, or rectum, is about 12 to 20 cm long and connects the colon to the anus.... The rectum collects stool from the large intestine and holds it until emptying..
Anus
The last part of the anatomy of the digestive system is the anus....a 4 cm long canal formed by the muscles of the pelvic floor and the anal sphincter (internal and external)....the anus covers the contents of the rectum..
Anus sphincter muscles are vital for stool control....they actually help you create the right angle between the rectum and the anus so that stool doesn't come out at the wrong time...having an internal sphincter prevents stool from entering the rectum while you sleep.
What conditions affect the components of the digestive system?
The factors affecting digestive anatomy are:
- Constipation
- Wound
- diarrhea
- Hemorrhoids
- Heartburn Gallstones
- Gastroenteritis (stomach flu)

Common diseases of digestive tract anatomy
They are:
- Colon disease Celiac disease
- Lactose intolerance Gastrointestinal cancers
- Diverticulitis
- Chronic acid reflux (GERD)
- Irritable bowel syndrome (IBS)

The result of the anatomy of the digestive system
The anatomy of the digestive system is so unique that it performs its tasks to convert your food into nutrients and energy needed by the body without the presence of special conditions and diseases.... Then the waste material is removed in the form of feces from the last part of the digestive system.... Some people think that the digestive system only includes the stomach....
