---|---|
Nasal Cavities | two spaces separates by a bony partition called the nasal septum, between the eyes. |
Nasal choana or conchae (choana=funnel) | curved projections along the lateral sides of the nasal cavities; filter out dust particles and warm and humidify the incoming air. |
Sinuses | small cavities in the bones of the skull; lined with mucous membranes; communicate with the nasal cavities. |
Pharynx (throat) | passageway lined with mucous membranes; connects the nasal cavities to the larynx |
Ororpharynx | the middle portion of the pharynx; lies directly behind the oral cavity; contains the palatine tonsils on its walls, and the lingual tonsils on the posterior tongue |
Laryngopharynx | the bottom portion of the pharynx; lies directly above the larynx. |
Larynx | a cartilaginous structure; contains the vocal cords and a small protrusion of cartilage commonly called the Adam's apple; also called the voice box. |
Glottis | the opening between the vocal cords. |
Epiglottis | a cartilaginous structure above the glottis; folds down over the glottis during swallowing to prevent food and water from entering the trachea. |
Trachea | (windpipe) a rigid tube made up of a series of horseshoe shaped cartilaginous rings, connects the pharynx to the bronchi of the lungs |
Mediastinum | anatomical space between the lungs; where the trachea, heart, major blood vessels, and esophagus are located. |
Bronchi | cartilaginous tubes that extend from the trachea into the lungs |
Bronchioles | small bronchi |
Terminal bronchioles | the last segments of the bronchioles; connect to the alveoli |
Alveoli | tiny sacs where gas exchange takes place in the lungs |
Surfactant | a lipid secreted in the alveoli; reduces surface tension of the water within the lung; decreasing the energy required to fill the alveoli with air. |
Pleural membranes | serous membranes associated with the lungs; produce a lubricant to reduce friction between the lungs and the walls of the pleural cavity. |
Parietal pleura | serous membrane surrounding the internal walls of the thoracic cavity. |
Visceral pleura | serous membrane lining the outer surfaces of the lungs. |
Tidal volume | the volume of air moved in or out of the lungs in one breath during quiet relaxed breathing (about 0.5L) |
Residual volume | the volume of air that remains in the lungs after maximum exhalation (about 1.2L) |
Vital capacity | the volume of air that can be exhaled after the maximum inhalation (about 4.8L) |
Total lung capacity | the total volume of air that can be contained in the lungs (about 6L) |
