Classroom Note:

The Alimentary canal

The digestive system, also known as the alimentary canal, is a series of connected organs leading from the mouth to the anus. The main parts include the mouth, esophagus, stomach, small intestine, and large intestine. This system breaks down food so that our body can absorb nutrients.

Parts of the Alimentary canal

  1. Mouth: Where digestion begins with the chewing of food and mixing with saliva.
  2. Esophagus: A tube connecting the mouth to the stomach, transporting food.
  3. Stomach: A sac-like organ where food is mixed with digestive juices.
  4. Small Intestine: A long, coiled tube where most nutrient absorption occurs.
  5. Large Intestine: Absorbs water and forms feces from undigested food.
  6. Rectum: Stores feces before they are expelled from the body.
  7. Anus: The opening at the end of the digestive tract where feces leave the body.

Evaluation Questions:

  1. Can you name the main parts of the alimentary canal?
  2. Why is the digestive system important for our health?
  3. Draw and label the alimentary canal.
