BIOS 1310 Exam #3 Questions And
Answers 2026 Update!!!
Nasal Cavity
Pharynx
Upper respiratory Tract Uvula
Larynx
Epiglottis
Superior nasal concha
Nasal Cavity Middle nasal concha
Inferior nasal concha
directs air into 6 meatuses
splits air stream and makes it swirl
Why?
Nasal Conchae
warming
traps particles
better sense of smell
3 divisions:
Nasopharynx
Oropharynx
Laryngopharynx
Pharynx Tonsils:
Pharyngeal
Palatine
Lingual
Uvula
, Produces thin mucus
Uvula Lubricates pharynx
for speech
Larynx contains vocal cords
vocal cords vibrate—→speech
thyroid cartilage
laryngeal prominence
cricoid cartilage
epiglottis
elastic cartilage
Epiglottis
closes during swallowing
Trachea
lungs
Lower Respiratory Tract Bronchi
bronchioles
alveoli
windpipe
c shaped cartilage
Trachea
holds it open
hyaline cartilage
Right: 3 lobes
Lungs Left: 2 lobes
to make room for the heart
site of entrance and exit of blood vessels,
Hilum
bronchi, etc.
, branching system of air tubes
Trachea—→Main bronchi—→Lobar bronchi—
Bronchial tree →Segmental bronchi—→bronchioles—
→terminal bronchioles—→Respiratory
bronchioles—→alveolar sacs—→alveolar ducts—
→alveoli
site of gas exchange
Alveoli
individual air sacs
conducting zone
Zones
respiratory zone
