Preview:
the body of the sternum and serves as the attachment for ribs 2-7
A. the manubrium
B. the corpus
C. the xiphoid process
a cartilaginous structure that allows air to pass from the nose and mouth into the lungs
A. trachea
B. bronchi
C. lungs
D. ribs
During quiet/passive exhalation____ from the stretched inspiratory muscles is released
A. potential (stored) energy
B. active expiratory pressure
C. recoil forces
D. non-muscular forces
developed by the contraction of the respiratory muscles, alveolar pressure is changed by____
A. passive force
B. active force
as the diaphragm moves downward, the force is transferred to the lower ribs moving them…
A. outward
B. inward
C. upward
D. down
due to the elastic properties of the respiratory system, the alveolar pressure is changed by____
A. passive force
B. active force
The ____ sits on top of the uppermost tracheal ring
A. larynx
B. esophagus
C. thorax
D. diaphragm
passive expiration is accomplished by
A. non-muscular forces (recoil forces)
B. muscular forces
C. potential (stored) energy
D. passive expiratory pressure
a membrane that covers the thorax
A. visceral pleura
B. parietal pleura
C. pleural linkage
the smallest branches stemming from the secondary bronci, lead to the alveoli where gas exchange occurs allowing air to enter into the blood
A. bronchioles
B. thorax

D. active pressure
a membrane that covers the lung
A. visceral pleura
B. parietal pleura

when they contract, they lift the ribs up and outward
A. diaphragm
B. external intercostal muscles
C. lungs
D. sternum
the external intercostal muscles are ____ forces of the respiratory system
A. active
B. passive
the lungs are apposed (or connected) to the thorax by….
A. pleural linkage
B. visceral pleura
C. parietal pleura
D. functional residual capacity
serves as a partial attachment for many muscles, the smallest
A. the manubrium
B. the corpus
C. the xiphoid process
has passive and active properties, during effortful tasks like coughing, sneezing, and certain voicing tasks, it contracts to compress the contents inside

D. abdominal wall
supplies innervation to the diaphragm
A. phrenic nerves ( C3,4,5)
B. spinal nerves
C. CN X
D. CN V
at rest, it sits in a dome-shaped position, when it contracts during inspiration, it moves downward and flattens, enlarging the chest cavity
A. diaphragm
B. abdominal wall
C. thorax
D. sternum
