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



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____

A. passive force

B. active force

the act of inspiration is always passive



major muscle of inspiration

A. diaphragm

B. lungs

C. abdominal wall

D. trachea

During quiet/passive exhalation____ from the stretched inspiratory muscles is released

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

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…
