Draw the diagram of the alimentary canal of a human and label the following parts:
Mouth,Oesophagus,Stomach,Intestine.

(N/A) The human alimentary canal is a continuous tube extending from the mouth to the anus. It consists of several organs that work together to digest food and absorb nutrients.
$1$. Mouth (Buccal cavity): The starting point of the alimentary canal where ingestion occurs and mechanical digestion begins with the help of teeth and saliva.
$2$. Oesophagus: $A$ muscular tube that carries food from the mouth to the stomach through peristaltic movements.
$3$. Stomach: $A$ $J$-shaped muscular organ that stores food and mixes it with gastric juices for chemical digestion.
$4$. Intestine: Divided into the small intestine (where major digestion and absorption of nutrients take place) and the large intestine (where water is absorbed and waste is prepared for excretion).
Refer to the provided diagram for the anatomical positions of these parts.
