Respiratory System Test Review

The exchange of gases between blood and cells is called

• pulmonary ventilation

• internal respiration

• external respiration

• cellular respiration

the nose serves all the following functions EXCEPT:

• as the initiator of the cough reflex

• warming and humidifying the air

• cleansing the air

• as a passageway for air movement

When the diaphragm and external intercostals muscles contract, which will NOT occur

• air moves into the lungs

• the intrapleural pressure increases

• the diaphragm moves inferiorly

• the intrapulmonary pressure decreases

During swallowing, the glottis is covered by

• false vocal cord

• true vocal cord

• epiglottis

• Adam's apple

Which of the following describes a correct order of structures in the respiratory passageway

• pharynx, trachea, larynx, bronchi, bronchioles

• larynx, pharynx, trachea, bronchioles, bronchi

• trachea, pharynx, larynx, bronchi, bronchioles

• pharynx, larynx, trachea, bronchi, bronchioles

the volume of air that can be exhaled and exhaled during a normal respiration cycle is the

• tidal volume

• residual volume

• inspiratory reserve volume

• expiratory reserve volume

During internal and external respiration gases move by

• osmosis

• active transport

• diffusion

• endocytosis

The main passageway that leads to the lungs from the throat is the

• pharynx

• epiglottis

• esophagus

• trachea

the first branches off the trachea are called

• bronchioles

• bronchi

• arterioles

• alveoli

what helps keep the alveoli inflated at the perfect size

• surfactant

• cilia

• mucus

• hemoglobin
