Respiratory System Quiz 2

The upper respiratory organs are lined with what type of epithelium in the trachea?

• Squamous epithelium

• Pseudostratified columnar epithelium

• Simple columnar epithelium

• Transitional epithelium

What is the primary function of the cilia in the respiratory system?

• To warm incoming air

• To beat debris to the pharynx to be swallowed

• To exchange gases at body capillaries

• To produce mucus

The alveoli are primarily responsible for:

• Warming and moistening incoming air

• Voice production

• Gas exchange

• Filtering debris from the air

What does the mucus in the respiratory system function to do?

• Trap debris

• Exchange gases

• Produce sound

• Transport gases in blood

Where does cartilage disappear in the respiratory system?

• Trachea

• Bronchioles

• Alveoli

• Bronchus

What type of cell is the alveoli primarily composed of?

• Stratified squamous epithelium

• Simple columnar epithelium

• Simple squamous epithelium

• Pseudostratified ciliated columnar epithelium

How do gases exchange between the alveoli and the capillaries?

• Oxygen diffuses from the capillaries to the alveoli, and CO2 diffuses from the alveoli to the capillaries.

• Oxygen diffuses from the alveoli to the capillaries, and CO2 diffuses from the capillaries to the alveoli.

• Both oxygen and CO2 diffuse from the alveoli to the capillaries.

• Both oxygen and CO2 diffuse from the capillaries to the alveoli.

Through which structure do the bronchi enter the lungs?

• Apex

• Base

• Hilum

• Mediastinal surface

What describes the visceral pleura?

• The outer layer membrane attached to the chest wall

• The layer of muscle beneath the lungs

• The inner layer membrane attached to the lungs

• The connective tissue linking the lungs to the diaphragm

What is the role of the parietal pleura?

• To cover the lung's surface directly

• To produce mucus for the respiratory tract

• To act as the outer layer membrane lining the thoracic cavity

• To facilitate gas exchange in the alveoli
