11. Which of the following statements regarding the lungs is correct?
- The anterior, medial, and posterior surfaces of each lung lie in close contact with the ribs
and together form the costal surface of each lung

notch

each other by connective tissue septae
12. Which one of the following statements is NOT correct
- The respiratory zone begins from the point where the terminal brochioles feed into the
respiratory bronchioles
- The respiratory bronchioles lead into the terminal cluster of alveoli called the alveolar sacs
3/8
Respiratory system Quiz
- The alveoli in the lungs account for most of the lung volume and provide a tremendous
surface area for gas exchange
- The alveolar pores perforating the inter alveolar walls are responsible for the passage of
air between the alveoli.
13. Which one of the under given structures is NOT a part of the respiratory membrane
-
alveolar epithelium
capillary endothelium
RBC membrane
fused basal laminae of alveolar epithelium and capillary endothelium
14. The type II pneumocytes are responsible for
- the secretion of large amount of mucus within the alveoli of the lungs
- the lining of alveolar walls from inside
- the secretion of a phospholipid and protein compound that reduces the surface tension
inside the alveoli
- the scavanging of foreign particles by the process of endocytosis within the respiratory
zone of each lung
15. All the statements related to thoracic wall are correct EXCEPT
- The thoracic wall is made up of twelve pairs of ribs and is completed anteriorly by a flat
bone called strenum
- The fibers of the external and internal intercostal muscles always run in opposite direction
from each other
- The external intercostal muscles are the muscles of expiration
- The movements of the thoracic wall and the diaphragm alter the volume of the chest
cavity and thereby move air in and out of the lungs

Respiratory system Quiz
16. Which one of the following statements regarding the pleurae is correct
- The fibrous pleura lines the thoracic wall and the supreior surface of the diaphragm
- The parietal pleura continues around the heart and between the lungs, forming the lateral
walls of the mediastinum
- Pleural cavity is a slitlike space between the visceral pleura and the outer surface of the
lung
- Parietal pleura is also known as the pulmonary pleura which dips into all the fissures of
the lungs
17. Which one of the following statements regarding diaphragm is NOT correct
- it is the most important muscle of inspiration
- the muscular component of the diaphragm is derived from the sternum, ribs, and the
lumbar vertebrae
- the relaxation of the muscle fibers of the diaphragm will lead to the flattening of its domes
during expiration.
- the central tendon of the diaphragm is fused with the inferior surface of the fibrous
pericardium

thyroid cartilage (T)
10. During swallowing, the epiglottis moves downward to cover the opening of the larynx (T)
11. The true vocal cords appaer pearly white because of the large amount of elastic fibers they
have underneath. (F)
12. The submucosal glands of the trachea help secreting large amounts of mucus that produce
thick "sheets of mucous" within the trachea (T)
