Front 1

Match the 4 aspects of respiration to their
description
1. Providing fresh air to the alveoli (Inhalation
and exhalation)
2. Gas exchange between alveoli and blood
3. Gas exchange between blood and tissue
fluid
4. Oxygen utilization in cell (to form ATP)

We can also divide the respiratory system
into upper and lower portions. List their
components.

nasopharynx, inferior larynx, trachea,
bronchi, and large bronchioles (air only)
4. Alveoli (gas exchange) –

Back 5

What structure (the potential site of an
emergency airway) occurs between the two
cartilages (thyroid/cricoid)?

Back 12

Cricothyroid ligament/membrane

Front 13

What spoon-shaped structure that protrudes
superior to the voice box folds over the
opening between the vocal chords during
swallowing?

Back 13

Epiglottis

Front 14

What do we call the opening between the
vocal chords?

Back 14

Glottis

Front 15

Two sets of folds occur in the voice box.
Match each to its description.
1. Elastic, medial, sound-producing folds
2. Inelastic, lateral, don’t produce sounds

Back 15

1. Vocal folds
2. Vestibular folds

Front 16

What is the technical term for the windpipe?

Back 16

Trachea

Front 17

Describe the structures that keep the
windpipe open. Explain why they have this
shape

Back 17

C-shaped cartilage rings
 Allow esophagus to distend

Front 18

Into what two tubes does the windpipe
bifurcate?

What do we call the groove, or concavity,
that provides an entry point for bronchi,
pulmonary vessels, and nerves?
