      The food that we eat needs to be broken down<\/strong> into smaller molecules to be able to be used by our body. The digestive system<\/strong> is a collection of organs<\/strong> that help in the process of digestion.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

      The digestive system is divided into two parts<\/strong>:<\/p>\n

        \n
      • The alimentary canal<\/strong> – this is the path the food that we eat takes.<\/li>\n
      • Other organs that helps in the process of digestion – food do not go through these organs.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

        The alimentary canal is a <\/span>series of organs that is hollow<\/strong> and provide a <\/span>pathway for food <\/strong>to enter <\/span>starting<\/strong> with the <\/span>mouth <\/strong>and end up <\/span>leaving<\/strong> via the <\/span>anus<\/strong>.<\/span><\/p>\n

        A lot happens when we put food into our mouth. When we put food in our mouth, our salivary glands<\/strong> start producing saliva <\/strong>which contains the enzyme salivary amylase<\/strong> which is a carbohydrase<\/strong>. This enzyme will break down starch <\/strong>(a carbohydrate) into simple sugars<\/strong> such as maltose.<\/p>\n

        <\/p>\n

        \n

        As we chew our food (mastication<\/strong>), the large pieces of food are broken down into smaller pieces. With the help of the tongue, the food is coated with saliva<\/strong>. This helps makes it easier to swallow<\/strong> our food.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

        Before reaching the stomach, the food we swallow will go through the oesophagus. To move food down, the <\/span>muscles in the walls<\/strong> of the oesophagus <\/span>contracts and relax<\/strong> in a wave-like pattern called <\/span>peristalsis<\/strong>. <\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

        The food then move from the oesophagus to the stomach where it is ready to <\/span>digest proteins<\/strong>. <\/span><\/p>\n

        <\/span><\/p>\n

        In the stomach, there’s <\/span>gastric juices<\/strong> which contains gastric acids which helps to <\/span>kill microorganisms<\/strong> and <\/span>proteases<\/strong> that is an enzyme that <\/span>digest proteins<\/strong>. <\/span><\/p>\n

        <\/span><\/p>\n

        The stomach is also a <\/span>muscular organ<\/strong> and mixes food with the gastric juices through a process called <\/span>churning<\/strong>. <\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

        <\/span><\/p>\n

        It performs <\/span>two important functions<\/strong>.<\/span><\/p>\n

          \n
        1. The small intestine <\/span>completes<\/strong> the <\/span>digestion <\/strong>of food including carbohydrates, proteins and fats.<\/span><\/li>\n
        2. The digested food is absorb <\/span>into the blood<\/strong> via the villi by a <\/span>process <\/strong>called <\/span>absorption<\/strong>. <\/span><\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n

          The pancreas <\/strong>produces pancreatic juice<\/strong> that contains all three enzymes, carbohydrase, protease and lipase. This pancreatic juice is secreted into the duodenum (small intestine).<\/p>\n

          \n

          The bile stored <\/strong>in the gall bladder<\/strong> is also released into the duodenum. Bile is secreted by the liver<\/strong>. It is important in the digestion of fats<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n
