The correct sequence for the movement of food in the alimentary canal is Mouth$\to$ Buccal Cavity$\to$ Pharynx$\to$ Oesophagus$\to$ Stomach $\to$ Small intestine $\to$ Large intestine $\to$ Anus
The mouth is the first part of the alimentary canal. Ingestion of food is done through the mouth.
The buccal cavity consists of the palate, tongue and teeth. Here, the food is broken into smaller pieces and mixed with saliva.
The pharynx is a common passage for air and food.
The oesophagus is a muscular structure that passes the food on from the pharynx to the stomach.
The stomach is a muscular bag present at the upper left part of the abdomen. It churns the food and digests proteins into smaller molecules.
The small intestine is the longest part of the alimentary canal. The digestion of food is completed here. The absorption of food takes place here as well.
The undigested food is compacted into faeces in the large intestine, and is then removed through the anus.
