Function Breathing Provide oxygen to
the body Inhalation
Remove carbon dioxide from the body Exhalation
Parts Nose Pharynx Epiglottis Larynx Trachea Lungs
Bronchi Bronchioles Alveoli
Nose Nostrils (nares)
Opening to the nasal cavity.
Lined w/ mucosa Septum
Cartilage that divides nasal cavity into R / L
Cilia Nasal hair Filters air
Pharynx (fair – inks)
Aka Throat 3 divisions
Nasopharynx Oropharynx Laryngopharynx
Double function Breathing Swallowing Connects nasal
cavity to the trachea
Epiglottis Flap of cartilage
tissue Covers the
esophagus while breathing
Covers the trachea and larynx while swallowing
Larynx (Lair – inks)
Voice box Vocal cords
Bands of tissue create the sound of your voice
Laryngitis Inflammation of the
vocal cords
Adam’s apple Cartilage that
surrounds the voice box Aka Thyroid cartilage
Trachea Aka ‘windpipe’
Breathing tube Connects the
larynx to the lungs Held open by ‘C’
shaped cartilage rings
Tracheotomy ER breathing hole
Bronchi 2 divisions off of
the trachea Main breathing
tube to each lung R / L bronchus Divides into smaller
air tubes called Bronchioles
Bronchioles Smaller branches
off of the bronchi Connects bronchi
to the alveoli Alveoli
‘grape like’ clusters
Form ‘air sacs’ Gas exchange takes
place here.
Lungs 2 cone shaped
organs Exchange gases
Pleura Membrane that
surrounds each lung Contains pleural fluid
Reduces friction while breathing
In dentistry the respiratory system relates to cross contamination (inhalation), hyperventilation, vital signs and administration of medications (N2O).
