2, draw and label the structural organization of trachea.describe in words how it functional works?

The trachea is a tube-like structure that connects the larynx (voice box) to the bronchi in the lungs. It is made up of rings of cartilage that provide support and prevent collapse of the airway. The inner lining of the trachea is lined with ciliated epithelial cells that help to trap and remove debris and pathogens from the air as it passes through.

The trachea functions by allowing air to pass from the larynx into the lungs, where oxygen is exchanged for carbon dioxide in the alveoli. The rings of cartilage in the trachea prevent it from collapsing and maintain an open airway for the passage of air. The cilia in the tracheal lining help to sweep mucus and trapped particles up towards the throat, where they can be coughed up or swallowed.

Overall, the structural organization of the trachea, with its cartilaginous rings and ciliated epithelial lining, allows for efficient and effective respiration by ensuring a clear and open airway for the passage of air into the lungs.
