Respiratory System Test

The conducting passageways of the respiratory system include all of the following structures EXCEPT

• pharynx
• larynx
• trachea
• esophagus

Which of the following is NOT a function of respiratory conducting passageways?

• allow air to reach the lungs
• humidify air
• exchange gases
• warm incoming air

Speech results from exhaled air causing vibration of

• voice box
• vocal cords
• epiglottis
• trachea

Cilia in the trachea that beat continually propel contaminated mucus

• toward the pharynx to be swallowed or spat out
• toward the mouth to be digested
• toward the nose to be sneezed out
• toward the larynx to be coughed out

The nasal cavity is separated from the oral cavity by

• the tongue
• the nasal septum
• the palate
• the trachea

Which of the following statements about the lungs is NOT true?

• The narrow portion of each lung is called the apex.
• The base rests on the diaphragm.
• The right lung has three lobes.
• They are the only major organ in the thoracic cavity.

Exchange of oxygen and carbon dioxide through the respiratory membrane occurs by

• simple diffusion
• active transport
• pressure changes
• passive transport

The exchange of air that occurs between the alveoli and pulmonary capillaries is

• internal respiration
• pulmonary ventilation
• inspiration
• external respiration

Which one of the following is NOT true of inspiration?

• contraction of the diaphragm muscle helps increase the size of the thoracic cavity
• relaxation of the external intercostals muscles helps increase the size of the thoracic cavity
• increased intrapulmonary volume causes inhaled gases to spread out
• air continues to move into the lungs until intrapulmonary pressure equals atmospheric pressure

Which one of the following is NOT true of expiration?

• the diaphragm relaxes
• it is mostly a passive process
• gas flows out to equalize pressure inside and outside the lungs
• intrapulmonary volume increases when the lungs recoil (get smaller)
