The correct option is D Mouth → Oesophagus → Stomach → Small intestine → Large intestine
The correct option is D.
Explanation for the correct option:
Option D:
- The alimentary canal is the main pathway through which the food enters the body, undergoes digestion, and is excreted.
- The digestive tract is divided into two regions - the alimentary tract and accessory organs.
- The alimentary tract is made up of the mouth, pharynx, esophagus, stomach, small intestines, and large intestine.
- The food ingested via the oral cavity is chewed and passed to the stomach via the esophagus.
- In the stomach, the food is converted to chyme that is transferred to the small intestine. The majority of nutrients are absorbed in the small intestine and the residual food is passed on to the large intestine.
- In the large intestine, reabsorption of water occurs and the solid waste is expelled via the anal canal.
