Larynx, Pharynx, Nasopharynx, Oropharynx

Question 2

Lower Airway

Answer 2

Trachea, Left/Right Bronchi, Bronchioles, Alveoli

Question 3

Total Lung Capacity

Question 4

Tidal Volume

Answer 4

Volume of air inhaled and exhaled during respiration cycle.

Question 5

Inspiratory Reserve Volume

Answer 5

Amount of air that can be inhaled plus the normal tidal volume.

Question 6

Minute Volume

Answer 6

Volume of air inhaled and exhaled in one minute.

Question 7

Functional Residual Capacity

Answer 7

Amount of air forced out from a single exhalation.

Question 8

Expiratory Reserve Volume

Answer 8

Amount of air left after normal exhalation.

Question 9

Answer 9

Amount of air left after maximal expiration.

Question 10

External Respiration

Answer 10

Between the lungs and the blood cells.

Question 11

Internal Respiration

Answer 11

Between the blood cells and body tissues.

Question 12

Hering-Breuer Reflex

Answer 12

The feedback loop responsible for ventilation.

Question 13

Intrapulmonary Shunting

Answer 13

Blood bypasses the damaged alveoli and returns to the heart un-oxygenated.

Question 14

High Levels of CO2

Answer 14

Leads to acidosis, results from hypoventilation. The production of CO2 is greater than the elimination.

Question 15

Low Levels of CO2

Answer 15

Hyperventilation. The elimination of CO2 is greater than the production.

Question 16

Hypoxemia vs. Hypoxia

Answer 16

Hypoxemia = Decreased level of O2 in arterial blood.
Hypoxia = Decreased level of O2 in body tissues.
