Respiratory System Structure and Function

Front

Which structure serves as the primary muscle of breathing and separates the thoracic and abdominal cavities?

Back

Diaphragm

Front

The exchange of gases between air and blood occurs primarily in the: Bronchioles, Trachea, Alveoli, Pharynx

Back

Alveoli

Front

Which of the following is measured by pulse oximetry? Lung capacity, Breathing rate, Tidal volume, Blood oxygen saturation

Back

Blood oxygen saturation

Front

The upper respiratory tract includes all EXCEPT: Nasal cavity, Pharynx, Bronchioles, Oral cavity

Back

Bronchioles

Front

What is the volume of air that remains in the lungs after a maximum expiration?

Back

Residual volume

Front

The conducting zone of the respiratory system: Contains alveoli, Begins at the trachea, Is where gas exchange occurs, Produces surfactant

Back

Begins at the trachea

Front

Which structure divides into the right and left main bronchi? Options: Pharynx, Larynx, Trachea, Bronchioles

Back

Trachea

Front

Spirometry measures: Blood oxygen levels, Heart rate during breathing, Air flow and lung volumes, Diaphragm movement

Back

Air flow and lung volumes

Front

The respiratory zone includes: Trachea and bronchi, Alveoli and respiratory bronchioles, Pharynx and larynx, Nasal and oral cavities

Back

Alveoli and respiratory bronchioles

Front

Peak flow measurements are most useful for monitoring: Sleep apnea, Lung cancer, Asthma, Pneumonia

Back

Asthma
