 Stomach Parts and Function

Major organ of digestive system are  Stomach parts

1. Mouth

2. Pharynx

Part of Pharynx

•  1 The nasopharynx is the part behind the nasicca 
•  2 The head pharynx (Oropharynx) is the origin of the tongue on the ground. 
• 3 Laryngopharynx- This is the part of the dietary nerves 

3. Oesophagus

The food through which the food reaches the stomach is called the food system or Alimentary canal. The esophagus begins with the 6th vertebra in the cervical region and is up to the 10th vertebrae of the thoracic region, which is situated below. The lower layer of the wall of the esophagus is there.

• Mucosa
• Submucosa
• Muscularis Externaa

4. Stomuch 

The stomach  is the widest part of the digestive system, one part of it is the esophagus and the first part of the small intestine opens on the duodenum.

5. Small intestine

The small intestine is covered with large intake of about 6-7 meters long. There are three sections of small intestine.

• Duodenum
• Jejunum
• Ileum 

6. Large Intesine

The large intake consists of the following seven parts.

• Cascum
• Ascending
• Transaction Colon
• Decending Colon
• Sigmoid collagen
• Rectum
• Anal  (Anus)

7. Rectum

It is about 12 to 18 cm long, spreading slightly below the bottom of the large intake. Its muscular layer is thicker. Mucosa in the rectum is a trap of veins when it blossomed, then the blood starts to flow out of which it is called piles or piles.

8. Anal (Anus)

Anal digestion system is the last part. This part is the destruction of stools. The caudal tube is made of a type of skeletal epithelium which merges into the rectum mucosa.

Stomach parts work

• Our digestive organ digest food, after digesting the nutritious things which are health-enhancing food, besides digesting the remaining things as stools.
• Mouth, teeth, tongue, lips, gums taste food and chew the food into small pieces.
• After this, saliva makes the food soft and wet so that it can be easily eaten.
• The task of delivering food from the mouth to the stomach is done through a tube, which is called esophagus.
• A type of acid is released in the stomach (stomach); The liver creates gall juice which is deposited in the gallbladder and pancreatic enzymes.
• All these juices are helpful in digesting the food, it lubricates the juice from the bile and digested food.
• The food stays in the stomach two to four hours, then goes into the small gap.
• The small intestine also makes enzyme. It digs food to pieces
• The small intestine absorbs vitamin, mineral and other nutritious food from food. Those foods which do not digest in the small intestine, reach in the middle.
• Due to illness, obstruction of small intervals
• The food in the gutter takes the form of stool
• Soak the water and nutritious things in the upper end, when the disease becomes ill, then the water gets absorbed and the stool starts to flow like water.

Function of stomach parts

Apart from stomach in digestion,  Liver, Gall bladder,  Pancreas, and Intestines also have very important functions.

List of organs that help in digestion process

Different organes participate in the digestive process or human digestive system: mouth, esophagus or food pipe, stomach or stomach, small intestine and large intestine.

1. Mouth

Digestion in humans starts with mouth. The mouth cavity or the buccal cavity contains teeth, tongue and salivary glands. The tooth breaks the food into small pieces, chews it and grinds it. Therefore, teeth help in physical digestion.

The salivary glands found in our mouth form saliva and with the help of tongue, saliva gets in the food.

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

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

2. Esophagus

A small digested food through the diet tube i.e. grasnali reaches the stomach. The walls of the diet tube contain muscles that may turn upside down and spread.

When a slightly digested food reaches the food pipe, the walls begin to shrink and spread, and it is called peristaltic movement in sequential circles, and this peristaltic movement sends food inside the stomach.

3. Stomach 

The food is brewed in the stomach for about three hours. During this time, the food breaks into even smaller 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 digestion of proteins present in the food to make very small particles. Therefore, digestion of the protein begins in the stomach.

4. Small intestine

The small intestine is a long, thin tube. Whose diameter is 1 inches 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 'stomatal respiratory muscular sphincter muscle'. This muscle sends food in small quantities to the small intestine.

Did 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 secrete the gall. 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 and below the stomach. The pancreas secretes the pancreas, which contains digestive enzymes such as pancreas amylase, trypsin and lipase. Amylage breaks the starch, tripsin digests the proteins and the lipase breaks the chemically broken fat.

The glands present in the walls of the small intestine secrete intestinal juices. 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.

5. 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 stomach and is wrapped around the small intestine.

After digestion, the food particles become smaller and reach through our small intestine and reach our blood. Blood carries digested and dissolved food to all parts of the body where it is incorporated into the cell form.

Less digested 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 untimely meal for some time and in the end it goes out of the body as an impure stool.

Apart from this, three different adrenal glands are helpful in the process of digestion: pancreatitis, liver and gallbladder.

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: It releases the bile which contains enzymes and helps in the digestion of fat.

Gallbladder: When the food filled with fat enters the small intestine, the bile sac shrinks and secrete the stored bile.
