Which statement describes the trachea?

• It is a passageway for food and for air.
• It contains no air-filtering mechanisms.

Pneumonia can be caused by

• viruses only.
• fungi only.
• bacteria only.

The first event in inspiration is

• the diaphragm moves downward and the external intercostal muscles contract
• decreased intra-alveolar pressure.
• lung inflation.
• atmospheric pressure forces air into the respiratory tract.

The first event in expiration is

• inter-alveolar pressure increases.
• elastic tissues of the lungs, thoracic cage, and abdominal organs recoil.
• air is squeezed out of the lungs.
• the diaphragm and external intercostal respiratory muscles relax.

A sudden inspiration caused by a spasmodic contraction of the diaphragm while the glottis is closed is a

• yawn.
• laugh.
• sneeze.
• hiccup.

The inverse relationship between pressure and volume is known as

• Dalton's law.
• Newton's law.
• Boyle's law.
• Starlings's law.
