Anatomy of the
Upper and Lower Respiratory System Structures
1. Complete the labeling of the diagram of the upper respiratory structures (sagittal section).
Cribriform plate of ethmoid bone
Superior nasal chonchea
Tongue Lingual tonsil tongue
Thyroid cartilage of larynx
Opening of auditory tube or eustachian tube or pharyngotympanic tube
2. Two pairs of vocal folds are found in the larynx. Which pair are the true vocal cords (superior or inferior)? Inferior vocal folds(true vocal fols)
3. Name the specific cartilages in the larynx that correspond to the following descriptions. thyroid cartilage
forms the Adam’s apple:
shaped like a signet ring:
a “lid” for the larynx:
vocal cord attac
4. What is the significance of the fact that the human trachea is reinforced with cartilaginous rings? to maintain passage way regardless to respiratory pressure change in tracheal wall.
Of the fact that the rings are incomplete posteriorly?
It provide space to oseseophagus to expland anteriorly so that large bolus can be swallowed.
plural membrane produce serous fluid which help in lubricating 5. What is the function of the pleural membranes?
and adhering both the membrane. It helps in keep lungs in thorasic cavity and can move easily during breathing movement. Warming, moisturing and
6. Name two functions of the nasal cavity mucosa.
filtering the passed air from nasal cavity.
7. The following questions refer to the primary bronchi.
left main bronchus
right main bronchus
left main bronchus
Which is longer?
Larger in diameter?
Right main bronchus
Which more commonly traps a foreign object that has entered the respiratory passageways?
8. Appropriately label all structures provided with leader lines on the diagrams below.

9. Trace a molecule of oxygen from the external nares to the pulmonary capillaries of the lungs: External nares � NASAL CAVITY----- PAHRYNX---TRACHEAS—PRIMARY BRONCHI--- SEONDARY BRONCHUS--- TERTIARY BRONCHUS ====BRONCHIOLE, PRIMARY BRANCHIOLE--- ALVEOLAR DUCT------- ALVEOLAR SAC-----ALEVOLAR/ CAPILALRY WALL--- PULMONARY BLOOD
