• Mouth → Oesophagus → Stomach → Small intestine → Large intestine

Answer 1

Mouth → Oesophagus → Stomach → Small intestine → Large intestine

Explanation:

The human alimentary canal is a one-way, continuous digestive tunnel where food travels sequentially:

• Mouth: Chews food and mixes it with saliva.
• Oesophagus: A muscular transport pipe that pushes food downward.
• Stomach: A muscular bag that churns and breaks down food with acid.
• Small Intestine: A long, coiled tube that completes digestion and absorbs nutrients.
• Large Intestine: A wider corridor that extracts excess water from the remaining waste.
