• remaining in the lungs after forced expiration.

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 respiratory muscles relax

The first event in inspiration is

• the diaphragm moves download and the external intercoastal muscles contract

• atmospheric pressure forces air into the respiratory tract

• intra-alveolar pressure is decreased

• the lungs become inflated

The trachea is described as

• passageway for food

• voice box

• a passageway for air

• all of these are correct

The pharynx functions as

• passage for air and food

• passage for air only

• passage for food only

• site to prevent objects from entering trachea
