Digestive glands :
Various glands are associated with alimentary canal serving the process of digestion of food. These are given below :
Salivary glands :
- These glands are of three types and secrete saliva containing an enzyme called Salivary amylase.
- It converts starch into sugar at an optimum pH of about 7.
- It is due to these salivary glands that our mouth waters when we eat or smell something we like.
Gastric glands :
- These are found in the wall of stomach.
- The gastric glands release digestive juice containing HCL, pepsin ,mucus, etc.
- Hydrochloric acid kills the bacteria ingested with the food.
- It creates and acidic medium of PH about 2, facilitating the action of pepsin enzyme.
- It acts on proteins present in food.
- Due to this highly acidic nature of HCL, the digestion of starch in stomach is prevented.
- It also prepares the ingested food for further processing in the small intestine.
- The mucus protects the lining of the stomach from the action of hydrochloric acid produced under normal conditions.
Liver :
- It's known as the largest gland of the body which secretes bile juice.
- These juices act on large fat molecules to form smaller globules, increasing the efficiency of enzyme action.
- Gallbladder stores bile juices for further use.
Intestinal glands :
- Walls of small intestine contain numerous glands that secrete intestinal juice containing Amylolytic, proteolytic and Lipolytic enzymes.
Pancreas :
- It secretes pancreatic juice which contains enzymes like amylase, trypsin and lipase.
- It is connected to the small intestine through its main duct called pancreatic duct.
