Digestive System in Urdu
Today in this post we will tell you briefly about the human digestive system in Urdu language.
In the below Urdu article, you will find detailed information on how human digestive system works. The digestive system of the human body is the system whose function is to digest food, extract the nutrients and vitamins from the food, and separate the waste from the nutritive food. Basically, the digestive system of the human body consists of gastrointestinal tracts also called digestive tracts. These digestive tracts consist of some structure and hollow organs through which all the food and liquids we drink are passed and fragmented by the digestive chemicals and enzymes into nutrients that have to be added to human body and waste that have to be excreted from human body.
After reading this you will completely understand the structure and functioning of human digestive system.
You will find it really easy to understand as the article is in Urdu/Hindi language.
Importance Of Human Body Digestive System
It is a very important system of the human body as our body need energy to do work and this energy can be obtained by the appropriate food we eat and liquids we drink. When we eat or drink this food enters our digestive system, then digestive system absorbs all the nutrients, minerals, vitamins, irons, carbohydrates, and calcium from this food. After absorbing it, it supplies these nutrients to our body or bloodstream. In this way human body gets energy for all his activities with the help of digestive system. Digestive systems also excrete all the waste of the human body which is very important too.
The digestive system of the human body starts from our mouth and ends at anus. In the way all the parts of digestive tract break the food and move it down of the system. After absorbing all the nutrients in the way, the waste is excreted from the human body. All the process of digestion is controlled by the nerves and hormones of human body.
Components and their Function in Digestive Tract
Mouth and Oral parts
The very first part of the digestive tract is a mouth. Food starts to digest when it enters the mouth. Firstly, the food is crushed by a mechanical process through our teeth.
Salivary Glands and Sliva
There are approximately 1000 salivary glands present in our mouth. As soon as our tongue tastes the food the sensors active the salivary glands to secrete saliva which soothes the food into a bolus.
After that, the food is moved down in digestive tract by means of our tongue. The food is further moved is moved down as we swallow. Here epiglottis is present which helps the food to move down easily and prevent choking. After this food reaches the esophagus.
After you start swallowing esophagus gets the signal from your brain and starts peristalsis and through peristalsis, food moves down to stomach.
When the food or liquid enters the stomach, it is mixed with digestive chemicals or enzymes. Digestive juices added with food with the help of stomach muscles. With these muscles the food is turned into chyme or a thick liquid which is then move to the small intestine.
The pancreas is an organ that produces enzymes that break down the food into fragments of vitamins, minerals, carbohydrates, and iron in the small intestine. These enzymes reach the small intestine by means of tiny tubes known as ducts.
Liver and Gallbladder
The liver produces bile which is a key juice to digest some vitamins. This bile is stored in the gallbladder. Bile is squeezed by the liver and by gallbladder to the small intestine of human body by means of bile ducts.
When the food reaches in the small intestine, digestive juice is added t to food with the pancreas juice as well as bile from the liver and gallbladder. These juices break down the food into nutrients, fats, and carbohydrates. The muscles of the small intestine absorb these nutrients alongside water and then these minerals and vitamins are then added to the bloodstream or where they are required. After all the required nutrients are absorbed the waste of the food is moved from small intestine to large intestine.
More water and the remaining nutrients are absorbed from the food when it reaches into the large intestine. The undigested food parts, unnecessary products during digestion of food, and big parts of food that cannot be digested become the waste of digestion process. After this more water is absorbed from this waste by large intestine, that turns this waste into dung or stool. This stool is stored in rectum, an organ below large intestine and then excreted.
Nerves and Hormones
Nerves and hormones of the human body control all the digestion process. Nerves are connected to brain and give signal to brain when to release the digestive juice or how much quantity should be released. They also control the expansion and contraction of muscles that make the food move down in the digestive system. Hormones control the human body by allowing digestive juices at right time and it also signals the brain that you need food or not. Stomach, pancreas, and small intestine release hormones that are very necessary for the digestive system of hum
