Respiratory System Review

Respiration is 

• breathing.
• making ATP.
• gas exchange between the atmosphere and cells.
• circulating blood to tissues.
• extracting energy from glucose.

The events of respiration are 

• inhaling and exhaling.
• ventilation, external and internal respiration, and cellular respiration.
• inflating and deflating alveoli.
• delivering carbon dioxide to cells and removing oxygen from cells.
• digesting and excreting.

The ultimate function of breathing is to 

• deliver oxygen to cells, where it takes part in the reactions of cellular respiration that liberate energy from nutrient molecules and get rid of carbon dioxide, which maintains the pH of the internal environment.
• inflate the lungs, which forces oxygen molecules into the bloodstream.
• deliver carbon dioxide to cells, where it takes part in the reactions of cellular respiration that liberate energy from nutrient molecules and get rid of oxygen, which maintains the pH of the internal environment.
• deliver oxygen to cells, where it takes part in the reactions of cellular respiration that liberate energy from waste molecules.
• deliver oxygen to cells during the day and deliver carbon dioxide at night.

Which of the following bones does not house a sinus?

• Maxillary
• Frontal
• Sphenoid
• Zygomatic
• Ethmoid

Which of these laryngeal cartilages is single?

• Cricoid
• Arytenoid
• Corniculate
• Cuneiform
• Marbular

The pitch of a vocal sound is controlled by changing the

• force of the air
• tensions on the vocal cord
• size of the laryngeal cartilages
• oral opening
• shape of the laryngeal cartilages

The vocal cords are in the 

• pharynx.
• larynx.
• trachea.
• oral cavity.
• nasal cavity.

Which of the following is NOT a function of the mucus-covered nasal passages? 

• Warming inspired air.
• Moistening inspired air.
• Entrapping small particles.
• Entrapping dust.
• Cooling exhaled air.

The procedure used to directly examine the trachea and bronchial tree is called 

• bronchoscopy.
• tracheostomy.
• tracheotomy.
• laryngectomy.
• lingualectomy.

The mucous membrane lining the nasal cavity 

• warms incoming air.
• moistens incoming air.
• entraps dust
• entraps other small particles.
• all of the above.
