Final answer:
The different glands related to our digestive system and their secretions are salivary glands (saliva), liver (bile), stomach (mucus), and the pancreas (insulin).
Step-by-step explanation:
The different glands related to our digestive system and their secretions are:
- Salivary glands: They secrete saliva which contains enzymes like amylase that begin the breakdown of carbohydrates.
- Liver: It produces bile which helps in the digestion and absorption of fats by emulsifying them.
- Stomach: It secretes mucus which helps in protecting the stomach lining from the acid and enzymes.
- Intestines: Insulin is not secreted by the intestines. Insulin is produced by the pancreas, which is an accessory organ, and it helps in regulating blood sugar levels, not digestion.
