HPP II Respiratory Material

An upper respiratory tract infection might include the following structures:

• bronchi
• alveoli
• trachea
• oropharynx

The paranasal sinuses serve to:

• warm the air
• cool the air
• dry the air
• all of the above

The main role of the olfactory bulb is in:

• cleaning the air
• mucus secretion
• smell
• speech

When air enters the nose, it will first come across the following:

• the epiglottis
• the conchae
• the oropharynx
• the laryngopharynx

The following statements about the glottis are true:

• it lies above the epiglottis
• it includes the trachea
• it is more taut in males
• it includes the vocal cords and space around them

In order to increase the efficiency of gas exchange, the respiratory membrane has a very ______ surface area and the pulmonary blood is spread very ______.

Pulse oximetry measurements inform you about which value?

• plasma pH or the concentration of H+ ions
• the partial pressure of O2 in the lung
• the partial pressure of O2 in systemic tissues
• the % saturation of hemoglobin with O2

Which of the following tissues are found in the rugged vocal cords?

• pseudostratified columnar epithelium
• simple squamous epithelium
• stratified squamous epithelium
• simple cuboidal epithelium

Which fluid do CO2 and O2 molecules cross to permit alveolar gas exchange?

The following structure is directly responsive to H+ ions and changes the rate of respiration:

• smooth muscle in lung
• carotid bodies
• cerebral cortex
• spinal cord
