Question

Which is the correct sequence of parts in human alimentary canal?

• A. Mouth $\to$ Stomach $\to$ Small intestine $\to$ Oesophagus $\to$ Large intestine
• B. Mouth $\to$ Oesophagus $\to$ Stomach $\to$ Large intestine $\to$ Small intestine
• C. Mouth $\to$ Stomach $\to$ Oesophagus $\to$ Small intestine $\to$ Large intestine
• D. Mouth → Oesophagus → Stomach → Small intestine → Large intestine

Answer 1

The correct option is D Mouth → Oesophagus → Stomach → Small intestine → Large intestine

• After the ingestion of food in the mouth, food is passed on from mouth to stomach through the oesophagus.
• Then food enters the small intestine for the digestion and absorption of proteins, carbohydrates and fats.
• Finally, it moves to the large intestine which is the last part of the alimentary canal where water is absorbed and undigested/ unabsorbed food is converted into a coherent mass of faeces and ejected from the body through a muscular anus.

So the correct answer is option D.
