Term
|
Definition
- connects Laryngopharynx to Trachea
- composed of many cartilages and muscles
- Thyroid cartilage = Adam's Apple - largest cartilage
- Epiglottis is attached to the Thyroid cartilage, this is elastic cartilage that separates the Respiratory from the Digestive System
- Glottis - contains the vocal cords which initiate speech |

Windpipe
- anterior to the Esophagus
- enters the Mediastinum then bifurcates to form the Primary Bronchi
- lined with Pseudostratified columnar epithelium, contains many cilia and Goblet cells
- has C shaped cartilaginous structures that cover the anterior 3/4 of the Trachea, for protection and maintains an open airway |

Definition
- a pair of cone shaped organs that fill the lateral thoracic cavities.
- Mediastinum separates the Lungs
- Apex - superior portion
- Base - the inferior surface that rests on the Diaphragm
- each Lung is surrounded by a double layer of pleura |

Definition
| when air enters the Pleural Cavity, can cause the Lung to collapse and put pressure on the heart |
|

Term
|
Definition
| inflammation of the pleura that causes friction, produces a sharp pain on inspiration |

a. Simple squamous epithelium (Type I Alveolar Cells)
- make up most of the walls of the alveoli
- the region of oxygen and carbon dioxide exchange between the Lungs & Circulatory System (i.e. External Respiration) |

Definition
| - secretes surfactant (this reduces the surface tension of the fluid in the alveoli which helps prevent their collapse) |
