    hi guyz

     

    today i would like to share with you about      DIGESTIVE SYSTEM IN HUMAN BEINGS

    The digestive system of human refers to the human alimentary canal and the organs and glands associated with it.

    Parts of the Human Digestive System and their Adaptive FeaturesIdentify parts of the human digestive System and their adaptive features

    THE MAIN PARTS OF ALIMENTARY CANAL

    The main parts are:- Mouth, Oesophagus, stomach, small intestine, (duodenum and ileum), large intestine (colon) and rectum.

    ADAPTATIONS OF STOMACH TO ITS MODE OF FUNCTION

    1. Stomach has sphincter muscles to prevent food from flowing back into the oesophagus
    2. Stomach has gastric glands, which produce gastric juice for the digestive process.
    3. Also in the stomach of a young baby there is renin which coagulates milk
    4. Stomachs have mucus which protects it from corrosion by digestive enzymes
    5. There is hydrochloric acid for the emulsification of fats and killing of bacteria

    ADAPTATIONS OF ILLEUM TO ITS FUNCTIONS

    The following are the adaptations of ileum to its mode of functions:-

    1. It has secretory glands, which produce digestive enzymes
    2. It is connected to the liver by the bile duct which enable the bile to reach ileum
    3. It has finger like projections called villi for the absorption of food
    4. The ileum is very long to ensure sufficient absorptions of food
    5. The villi have large network of blood capillaries for transporting absorbed food to all parts of the body
    6. The inner lining of the ileum is folded to increase the surface area for absorption
