Answer:
Oral Cavity, Oesophagus, Stomach, and Small intestine
Explanation:
Parts of the body are considered part of the alimentary canal are Oral Cavity, Oesophagus, Stomach, and Small intestine because the Oral Cavity includes the lips, the inside lining of the lips and cheeks (buccal mucosa), the teeth, the gums, the front two-thirds of the tongue, the floor of the mouth, below the tongue, and the bony roof of the mouth (hard palate).
The Oesophagus connects the throat to the stomach; which is the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.
The stomach is located between the esophagus and the small intestine. It secretes digestive enzymes and gastric acid to aid in food digestion. It is a muscular hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates.
The Small intestine or small bowel is an organ in the gastrointestinal tract where most of the end absorption of nutrients and minerals from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion.
