The ringed windpipe in a bird, known as the trachea, is a flexible tube that connects the throat to the lungs. Unlike mammals, birds have a trachea that is reinforced with complete cartilage rings, which help maintain the shape of the airway during breathing. This structure is crucial for their unique respiratory system, allowing for efficient airflow and gas exchange necessary for flight. Additionally, the trachea can expand and contract, helping birds produce vocalizations.
