What is the name of the long, continuous tube that runs from the mouth to the anus and is responsible for processing food to release nutrients and energy?

The alimentary canal, which is also known as the digestive tract, is a critical part of the human body responsible for digesting and processing food. It is a long, continuous tube that extends from the mouth to the anus and is divided into various sections, including the mouth, oesophagus, stomach, small intestine, large intestine, rectum, and anus.

Each part of the digestive tract plays a specific role in breaking down food, absorbing nutrients, and eliminating waste. The process of digestion begins in the mouth, where food is mechanically broken down before passing through the oesophagus into the stomach. From there, the small intestine absorbs nutrients from the food, while the large intestine and rectum are responsible for expelling waste from the body.

Therefore, the correct answer is the alimentary canal.
