Hi, reader, do you wanted to know how the food digest in human body. In this article, we write how do we digest the food that we consume? You can understand easily how the digestion process happens.

Food digestion process in the mouth



    Many people have only the myth of the size, shape position, and function of the stomach and the other digestive organs.
    To extract nutrients from the food, we eat we need to digest it. First, the food has to change into a liquid or semi-liquid form. Then, complex substances such as fats and proteins have to be broken down into the smaller chemical unit that can be absorbed through the walls of the intestine into the bloodstream.

    Digest Food

    The process of digestion begins in the mouth, where the teeth and tongue chop large pieces of food into smaller ones. The salivary gland release saliva into the mouth to mix with the food. Saliva makes it easier to move food round to chew, and it also contains an enzyme called salivary amylase that starts to digest carbohydrates such as sugars and starches.

    Saliva is slightly acid, and when you are not eating, it goes on being produced and helps to keep your mouth and teeth clean and stop developing plaques on your teeth.
    People who have conditions in which salivary production is reduced often experience dry mouth, difficulty in swallowing, and increased tooth decay.

    Digestion process in the stomach


    Once the food is chewed and softened in the mouth, the tongue pushes the food to the back of the throat, where muscles propel it down the esophagus into the stomach through a muscular one-way valve, called the lower esophagus when the stomach contracts or you lie flat.
    Eventually, liquidized food is pushed onwards through another valve, the pylorus, into the duodenum, the first few inches of the small intestine. Here, further chemicals are added to neutralize the stomach acid, together with enzymes from the pancreas to help digest carbohydrates, fats, and proteins, and bile from the liver to help to digest fats.

    Intestinal digestion process


    The digested food then passes into the remaining 20 feet (six meters) of the small intestine, so-called because, although it is long, its diameter is lower than that of the large intestine. The chemical breakdown is completed in the small intestine, and the useful chemical constituents of the meal are absorbed into the blood and lymphatic vessels.
    The main task of the large intestine is to reabsorb the water that is used in digestion and to eliminate the undigested food and fiber.
