Question

What is the reason behind the glands ( liver, pancreas, and salivary glands ) not constituting in the alimentary canal? Please suggest.

Thank you so much!

Answer 1

Explanation:

• The alimentary canal is the way of food whether digested or undigested.
• Here the food has to react with enzymes and other chemicals during digestion.
• If other glands were present in the alimentary canal then the passage of food becomes difficult.
• The glands might also block the enzymes or chemicals which reach food and obstruct digestion
• That's why glands are not present in the alimentary canal.

I hope that this answer was useful.

Thank you

Answer 2

Answer:

The glands ( salivary glands,liver and pancreas ) help in digesting food but do not store food.Whereas the organs of alimentary canal store food.Thus, the glands are not the part of the alimentary canal.
