Various digestive glands are:

  • Salivary glands

  • Glands present in stomach

  • Pancreas

  • Liver and gall bladder

  • Secretions of small intestine

  • Secretions of large intestine

Salivary glands

Digestion in GIT - Digestion of lipids

Diet: Almost all of the dietary lipids are triglycerides (neutral fats), small quantities of cholesterol, lecithin etc are also present. Triglycerides are made up of a single glycerol molecule and three fatty acid molecules. These are present as mono-, di- and tri-glycerides.


In mouth; lingual lipase is not of much importance.
