What is the passage from the Pharynx to the stomach called?

The passage from the pharynx to the stomach is called the esophagus. This muscular tube plays a crucial role in the digestive system, as it is responsible for transporting food and liquids from the throat down to the stomach.

When you swallow, the muscles in the esophagus contract in a wave-like motion known as peristalsis, which helps push the food towards the stomach without allowing it to go back up. The esophagus serves as a conduit connecting the pharynx, where food enters after being chewed, to the stomach, where digestion begins.

Understanding the function of the esophagus is essential for grasping how the digestive process works, as it underlines the coordinated movements that facilitate swallowing and food transport in the body. The other choices refer to different structures that do not serve this function. The trachea is the windpipe that leads to the lungs, the duodenum is the first part of the small intestine following the stomach, and the colon is part of the large intestine, none of which are involved in the passage from the pharynx to the stomach.
