What do the C-shaped rings do for the Trachea? prevents the Trachea's collapse or overexpansion Where is the open part of the C-shaped ring in the Trachea and what does it do? it is anterior to the esophagus which allows it to expand during swallowing. What is the Epiglottis? a lid over the entrance of the trachea which closes off the laryngopharynx What is the Trachea lined with? it is lined with mucous membranes and hair-like processes called "Cilia" What is Cilia in the Trachea? hair-like projections that line the primary bronchus to remove microbes and debris from the interior of the lungs What are the parts of the BRONCHIAL TREE? **the trachea divides into 2 BRONCHI (primary bronchi) as it enters the lungs **these bronchi divide into smaller branches called BRONCHIOLES in the lungs. **the bronchioles end in small grape-like clusters called ALVEOLI (air-sacs), the location for gas exchange in the lungs What is Alveoli? air-sacs, filled with air Each lung contains how many Alveoli? millions of Alveoli What are the Alveoli surrounded by? blood capillaries where the exchange of carbon dioxide and oxygen occurs What are the Alveolus coated with? a thin covering of Surfactant What is Surfactant?

General Functions of the Respiratory System Air Passageway,Site for the Exchange of Oxygen and Carbon Dioxide,Detection of Odors,Sound Production upper respiratory tract The nose, nasal cavity, and pharynx lower respiratory tract larynx, trachea, bronchi, bronchioles (including terminal and respiratory bronchioles), alveolar ducts, and alveoli conducting zone Passageways that serve primarily to transport or conduct air respiratory zone
