Anatomy of the
Respiratory System

Upper and Lower Respiratory System Structures

1. Complete the labeling of the diagram of the upper respiratory structures (sagittal section).

Frontal sinus

Cribriform plate of ethmoid bone
Superior nasal chonchea
middle inferior

external nares

Hard palate
epiglottis
Tongue Lingual tonsil tongue
Hyoid bone

Thyroid cartilage of larynx
Cricoid cartilage

Thyroid gland

trachea

Sphenoidal sinus

Pharyngeal tonsil

Opening of auditory tube or eustachian tube or pharyngotympanic tube

Nasopharynx
Soft palate

laryngopharynx glottis
epophagus

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

cricoid cartilage

forms the Adam’s apple: shaped like a signet ring:

epiglottis
a “lid” for the larynx: vocal cord attac

arytenoids cartilage

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
