olfaction
air filtration
elimination of wastes
Disorders of Respiration
Emphysema
Pneumonia
Asthma
Pleurisy
Emphysema
Alveoli coelesce( Reduce surface area) Lose elasticity
Pneumonia
viral/bacterial infection WBC/ fluid accumulates in lungs
Gases can't exchange
Asthma
constriction of airway smooth muscle
Pleurisy
inflammation of pleura due to infecton/trauma
Structures
Nose
Nasal Cavities
Paranasal Sinus
Pharynx
Larynx
Nose
Skin over bony framework
Distally hyaline cartilage
External nares(nostrils) where nasal cavities open to exterior
Internal nares where nasal cavities open into nasopharynx
Paranasal Sinuses
Warm, moisten
Resonating chamber
Pharynx(throat)
Superiorly communicates with nasaloral cavities
Inferiorly communicates with larynx/esophagus
3Portions
Nasopharynx
upper portion(above soft palete)
soft palete and uvula form floor
auditory tube opens into
pharyngeal tonsils on posterior wall
lining pseudostratified ciliated columnar epithelium
3portions
Oropharynx
middle
between soft palate/hyoid
anterior wall base of tongue
palatine and lingual tonsils
lining stratified squamous epithelium
3portions
Laryngopharynx
Lower
Below hyoid
Lining stratified squamous epithelium
Inferiorly, opens into larynx anteriorly
opens into esophagus posteriorly
Larynx(voice box)
Connects laryngopharynx and trachea
Muscles/ligaments hold 9 cartilages together to form larynx
Lining ciliated pseudostratified columnar epithelium/goblet cells
9 Cartilages:
1.Thyroid (adams apple) largest triangular shape
2.cricoid ring shaped,below
3.epiglottis leaf shaped/lid over glottis
4.arytenoid(2) vocal cords attach to
5.cuneiform(2) smallclub shaped
6.Corniculate(2) smallhornshaped
Functions of Larynx
air passage
protective sphincter
sound production
Vocal cords
2pairs of mucous membrane folds stretch horizontally across entrance into larynx
From thyroid cartilage to arytenoid cartilage
Ventricular folds
upper
"false" vocal cords
support true vocal cords
True Vocal Cords
Lower
Vocal Folds
Within folds are elastic ligaments
Vibrate in sound production
Intrinsic muscles adjust tention (narroe/widen glottis)
Extrinsic muscles
elevate muscles
