The vertebrate trachea, also known as the windpipe, plays an essential role in breathing as it connects the throat to the lungs. There are several synonyms for this organ, including the respiratory tube, breathing tube, airway, bronchial tubes, and pulmonary conduit. The respiratory tube is a vital component of the respiratory system, providing a direct pathway for air to enter and leave the lungs. The breathing tube is composed of cartilage rings that maintain its structural integrity, ensuring the trachea does not collapse during inhalation and exhalation. As an airway, the vertebrate trachea is responsible for transporting oxygen from the outside environment to the cells of the body.
