What does the medical term "trachea" refer to?

The medical term "trachea" specifically refers to a tube that extends from the throat to the lungs. This structure is an essential part of the respiratory system as it serves as the main airway, allowing air to flow in and out of the lungs during breathing. Its composition includes cartilage rings that keep it open and flexible, facilitating the passage of air and playing a vital role in the conduction of airways.

The trachea's primary function is to transport air, making it crucial for delivering oxygen to the lungs and removing carbon dioxide from the body. Understanding the anatomy and function of the trachea contributes to a greater comprehension of respiratory health and disease.
