The alimentary canal, also known as the digestive tract, is a crucial part of our digestive system. It’s a tube-like structure that starts from the mouth and ends at the anus. Let’s explore the key organs along this pathway:

1. Mouth and Oral Cavity:
   • The mouth is where food enters our system.
   • The oral cavity includes the palate, tongue, and teeth.
   • Teeth come in different types (incisors, canines, premolars, and molars) and serve various functions like cutting, tearing, chopping, and grinding.
   • The tongue has tiny projections called lingual papillae.
2. Pharynx:
   • The common passage for both food and air.
   • The epiglottis prevents food from entering the windpipe.
3. Oesophagus:
   • A muscular tube that transports food from the mouth to the stomach.
   • The gastro-oesophageal sphincter controls food movement into the stomach.
4. Stomach:
   • A muscular bag located in the upper left part of the abdominal cavity.
   • It has four parts: cardiac, fundus, body, and pyloric portion.
   • The cardiac part regulates the opening between the oesophagus and the stomach.
5. Small Intestine:
   • The primary site for nutrient absorption.
   • Consists of three parts: duodenum, jejunum, and ileum.
6. Large Intestine:
   • Responsible for water absorption and formation of feces.
   • Includes the cecum, colon, and rectum.
