In the Digestive system of human beings, those organs are added which also work to chew, swallow, digest and absorb food, and even work out the digestible food. It also contains many different types of glands Let us study the list of those organs through this article which help in digestion.
Digestion in humans starts with 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:
ग्रासनली 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.
आमाशय 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 digestion of proteins present 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 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 ‘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 small intestine is the place of whole digestion i.e. carbohydrate protein and fat.
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.
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/
It releases Bile which contains enzymes and helps in the Digestion of fat.
