Respiratry System

Why is nose breathing preferable to mouth breathing

• Nose breathing is easier thus allowing less stress on the lungs

• Nose breathing cleans, humidifys, and warms incoming air

• Nose breathing allows for less droplet transfer of viruses/bacterias

• It does not make a difference

What is the specific protective function of cilia in the trachea

• To move contaminants away from the lungs

• To move air toward the lungs

• To move contaminants toward the alveoli

• To move air toward the alveoli

Reorder the following

• nasal cavity

• trachea

• alveoli

• bronchi

• larynx

Reorder the following

• alveoli

• trachea

• bronchi

• bronchioles

• pharynx

Which main bronchus is the most likely site for an inhaled object to become lodged?Why?

• The right, because its wider and straighter

• The left, because its wider and straighter

• The right, because there are 3 lobes allowing for more possible routes.

• The left, because there are 2 lobes allowing for wider straighter path

The lungs are mostly passageways and elastic tissue

• True

• False

What is the roll of the passage ways inside the lungs

Name the 4 resiratory structures that make up the respiratory zone

What is the most basic function of respiration

• To facilitate breathing

• To exchange oxygen & carbon dioxide

• To exchange blood and oxygen particles

• To facilitate the transport of oxygen and carbon dioxide

What causes air to flow out of the lungs during expiration

• Increased pressure in the lungs as they expand

• Decreased pressure in the lungs as they recoil

• Increased pressure in the lungs as they recoil

• Decreased pressure in the lungs as they expand
