Structure and Functions

Question 1

What are the upper airway?

Answer 1

Pharynx
Larynx
Oropharynx

Question 2

Pharynx

Answer 2

Cavity posterior to the nose and throat

Question 3

Larynx

Answer 3

Nasal Area
Located at the top of trachea/ where vocal cords are found

Question 4

Oropharynx

Answer 4

Throat or Mouth

Question 5

What happens to air taken in through these pathways?

Answer 5

Warm
Filter
Humidify

Question 6

What are the lower airways?

Answer 6

Trachea
Bronchi
Bronchioles
Alveoli of the Lungs

Question 7

Trachea

Answer 7

Divides into the bronchial tubes within the lungs

Question 8

Alveoli of the Lungs

Answer 8

Gas exchange takes place.

Question 9

Where does gas exchange take place?

Answer 9

Alveoli and capillaries

Question 10

What is the responsibility of the lungs?

Answer 10

Providing oxygen to the body and removing carbon dioxide.

Question 11

How many lobes does the right lung have?

Answer 11

3

Question 12

How many lobes does the left lung have?

Answer 12

2

Question 13

What is the role of the lungs?

Answer 13

Ventilation
Inhalation
Exhalation

Question 14

Inhalation

Answer 14

When a person inhales, the diaphragm and the intercostal muscles contract, creating a negative pressure inside the lungs and the thorax increases in size.

Question 15

Exhalation

Answer 15

When a person exhales, the diaphragm relaxes and the intercostal muscles contract, so that gas inside the lungs is expelled.

Question 16

Gas Exchange

Answer 16

Oxygenate blood travels to the cells of the body and the body gets rid of Carbon Dioxide (CO2)

Question 17

Ventilation

Answer 17

The flow of air inside and outside of the alveoli.

Question 18

Perfusion

Answer 18

Exchange of deoxygenated blood is for oxygenated blood in the heart, with the oxygenated blood then being delivered to the rest of the body.

Question 19

Respiration

Answer 19

Inhaling of oxygen and the exhalation of carbon dioxide.

Question 20

How are respiration’s regulated?

Answer 20

Chemoreceptors sense gasses levels of Carbon Dioxide, Oxygen, Hydrogen ion of the blood and altered respiratory pattern to maintain homeostasis.

Question 21

How does impairment impact the other organs of the body?

Answer 21

Lungs are requited to inhale oxygen so that the heart may pump oxygenated blood to the rest of the body.

Question 22

Cor Pulmonale

Answer 22

Damage of lungs increases pressure on the Right Ventricle causing right sided heart failure.

Question 23

What separates the lower and upper airways?

Answer 23

Epiglottis

Question 24

Bronchoconstriction

Answer 24

Tightening of the bronchus due to the contraction of the smooth muscle.

Question 25

What nervous system causes bronchoconstiction?

Answer 25

Parasympathetic

Question 26

Bronchodilation

Answer 26

Expansion of the airway in the bronchus.

Question 27

What Nervous System causes bronchodilation?

Answer 27

Sympathetic

Question 28

Atelectasis

Answer 28

Complete or partial collapse of the entire lung or area (lobe) of the lung.

Question 29

When does Atelectasis take place?

Answer 29

When the tiny air sac (alveoli) within the lung become deflated or possibly filled with alveolar fluid.

Question 30

Airway Resistance

Answer 30

Pressure of tissues in the airway to the flow of air.

Question 31

Inspiratory Respiratory Reserve

Answer 31

Volume of air inhaled during a typical inhalation.

Question 32

Tidal Volume

Answer 32

Volume of air inhaled and exhaled.

Question 33

Residual Volume

Answer 33

Volume of air in alveoli after exhalation.

Question 34

Forced Vital Capacity

Answer 34

Volume of air remaining in lung after maximum inhalation.

Question 35

Vital Capacity

Answer 35

Max volume of air that is exhaled after max inhalation.

Question 36

Total Lung Capacity

Answer 36

Volume of air remaining in the lung after max inhalation.
