What is the Alimentary canal?
The long passage that starts from the Mouth and ends at Anus is known as the alimentary canal or Gastrointestinal Tract. This long pipe has modified structures depending upon the needs of the body.
What are Different parts of the alimentary canal?
Different parts of the alimentary canal are the mouth, oesophagus, stomach, small intestine, large intestine, rectum, and anus.
- It is the part where the digestion starts.
- The chewing of the food by teeth breaks the food down into tiny pieces.
- Saliva produced by Salivary Glands helps in the breakdown of Starch.
- It also makes the food easier to swallow by forming a Bolus. A bolus is a ball-like structure made up of food and saliva.
