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
alveolar pressure is changed by 2 forces: passive and active forces
A. TRUE
B. FALSE
diaphragm and external intercostal muscles
A. muscles of quiet inspiration
B. muscles of forced inspiration
due to the elastic properties of the respiratory system, the alveolar pressure is changed by____

B. active force
the act of inspiration is always passive
A. TRUE
B. FALSE
major muscle of inspiration
A. diaphragm
B. lungs
C. abdominal wall
D. trachea
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
When the respiratory system is at rest, the lungs are partially ____ at “rest”
A. inflated
B. deflated
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
C. lungs
D. diaphragm
when they contract, they lift the ribs up and outward
A. diaphragm
B. external intercostal muscles
C. lungs
D. sternum
during inhalation the lung volume increases, air molecules are less compressed, creating a vacuum called…
