Describe the alimentary canal of man.

(N/A) The alimentary canal of man is a long,muscular tube that extends from the mouth to the anus. It consists of the following parts:
$1$. Mouth and Buccal Cavity: The process of digestion begins here with the ingestion of food,mastication by teeth,and mixing with saliva.
$2$. Oesophagus: $A$ muscular tube that transports food from the pharynx to the stomach through peristaltic movements.
$3$. Stomach: $A$ $J$-shaped organ where food is mixed with gastric juices containing $HCl$,pepsin,and mucus for protein digestion.
$4$. Small Intestine: The primary site for complete digestion and absorption of nutrients. It is divided into the duodenum,jejunum,and ileum.
$5$. Large Intestine: It absorbs water and electrolytes from the undigested food and forms feces,which are stored in the rectum and eliminated through the anus.
