👉 The trachea is a muscular tube that connects the larynx to the windpipe. It is also known as the bronchus and serves as an airway for breathing, allowing air to enter the lungs. The tracheal walls are lined with纤毛细胞,使它具有分泌粘液的功能。
👉 The term "tracheated" refers to a specific type of lung that is primarily responsible for producing mucus, which helps in phlegm clearance and also plays a role in the maintenance of respiratory function. The primary part of the trachea (windpipe) is located at the base of the neck, while the tracheobronchial tree extends from the trachea down to the bronchi. This structure is responsible for delivering air to various organs within the body.
