Question

how are the flexible walls of the oesophagus useful?​

Answer 1

Hello DUDE...

Flexible walls help are very useful in the following ways:

1. They help in better transportation of food from the buccal cavity to the stomach.
2. If the oesophagus had a definite shape, we can't bend.
3. Big food particles could even struck in the oesophagus and this would have led to death.

Answer 2

Answer:

When you swallow food, the walls of the oesophagus squeeze together (contract). This moves the food down the oesophagus to the stomach. The upper part of the oesophagus is behind the windpipe (trachea). ... It is moist to help food pass smoothly into the stomach.
