The primary bronchi, the larynx, the terminal bronchioles.
The terminal bronchioles
The larynx
7. Forced expiratory volume tests are used to differentiate between restrictive and obstructive lung disorders
True
False
8. What is the definition of inspiratory reserve volume?
The amount of extra air exhaled during a forceful breath out.
The amount of extra air inhaled during a deep breath.
This is the vital lung capacity plus the residual volume and is the total amount of air lungs can hold.
The amount of air left in the lungs following a maximal exhalation.
9. What is the role of intrapleural pressure?
Negative intrapleural pressure acts a suction, so the outer part of the lung lobe tissue is stuck to the back of ribs and connective tissue and diaphragm moves down, lung tissue goes with it
None of the above.
To regulate breathing
To increase movement of thorax
10. Fibrosis will......... compliance making it harder to inflate the lungs.
Make no difference.
Decrease
Increase
None of these are correct.
11. What is quiet inspiration?
Active process that requires muscle action where thorax volume increases and lungs expand
Passive process with no muscle action
Process in which alveoli gas exchange occurs.
None of the above
12. What pressure change occurs during quiet inspiration?
Intrapleural pressure
Alveolar pressure decreases below atmospheric pressure and air moves into alveoli
Intrapulmonary pressure
None of the above
13. Which muscles control expiration?
Internal intercostals, external oblique and rectus abdominus
16. The partial pressure of oxygen decreases at high altitude because the amount of oxygen in the air is decreased.
False
True
17. Carbon monoxide is lethal because it..
Increases oxygen unloading at the cells.
Binds haemoglobin preventing oxygen binding.
Increase CO2 and causes seizures.
Reduces CO2 and slows breathing.
18. What is the primary bronchi?
The terminal bronchioles
Trachea
Layrnx
The respiratory bronchioles
19. Is inspiration at rest an active or passive process?
Active
Passive
20. What is pulmonary ventilation?
air moves into lungs when pressure inside lungs is less than atmospheric pressure, air moves out of lungs when pressure inside lungs is greater than atmospheric pressure
all of the above
the pressure exerted by the gases that make up the air that surrounds the earth
