Digestive Glands

Digestive Glands: The main digestive glands which secrete digestive juices are: 1. Salivary Gland  2. Liver  3. Pancreas

  • Salivary Gland : Salivary gland is a group of organs present in our mouth that secretes saliva. It is found in mammals only. Saliva contains various chemicals with water including mucus, salts, antibacterial substances, enzymes and chemicals that control the pH in the mouth.
  • Liver : The largest gland of the body, liver is a reddish brown coloured gland, situated in the upper part of the abdomen on the right side. It secretes bile juice which is stored in a sac like structure called as ‘gall bladder.’ The bile juice helps in digestion of fats. The complete digestion of fats is done by pancreatic juice.
  •                                  

    Pancreas: It  is a large cream coloured gland which is located just below the stomach and secretes pancreatic juices. It breaks down fats into simpler compounds like fatty acid and glycerol, carbohydrates into simple sugars and proteins into simpler amino acids. Now the food is said to be digested. This digested food is now absorbed by the walls of small intestine.
