1. DIGESTIVE GLANDS IN HUMAN By, ASWATHI P V NATURAL SCIENCE NO.25 KUTEC DHARMASALA

2. Digestive glands associated with alimentary canal includes Salivary gland Liver P ancreas

3. Salivary gland Saliva is mainly produced by three pairs of salivary glands. Parotid gland (on lower jaw) Sub-maxillary /Sub-mandibular(on lower jaw) Sub lingual gland(below tongue)

4. Salivary gland produces saliva . It’s pH 6.8

5. Saliva contains Mucus – helps in lubrication. Lysozyme – act as an anti bacterial agent Salivary amylase – converts starch to maltose. Electrolyte(Na +. , K + ,cl - ,HCo 3 ) – For maintain the slightly acidic pH of saliva(6.8) /act as buffer.

6. Liver Largest gland in human body Liver has two lobes. Liver cell – Hepatic cell The two lobes of liver are called hepatic lobules.

7. Hepatic lobules are the structural and functional unit of liver. Each lobule is formed of hepatic cells. Bile is secreted by hepatic cells. Bile is stored in gall bladder.

8. Pancreas Second largest glands. Heterocrine gland Secrete pancreatic juice Opens into the duodenum along with the bile duct .

9. The bile duct and pancreatic duct open together into the duodenum as the common hepato pancreatic duct which is guarded by a Sphincter called Sphincter of Oddi.
