Respiratory System Review

The conducting passageways of the respiratory system include all of the following structures EXCEPT

• Nose

• Pharynx

• Larynx

• Alveoli

Exchange of both oxygen and carbon dioxide through the respiratory membrane occurs by:

• simple diffusion

• passive transport

• facilitated diffusion

• active transport

The amount of air remaining in the lungs even after the greatest possible expiratory effort is the

• residual volume

• dead space volume

• expiratory reserve volume

• tidal volume

Cilia of the trachea that beat continually propel contaminated mucus

• toward the throat to be swallowed or spat out

• toward the nose to be sneezed out

• toward the epiglottis to be coughed out

• toward the lungs to be encapsulated

• toward the glottis to be hiccuped out

Which one of the following is NOT true of the lungs

• the narrower portion of each lung is called the apex

• the base rests on the diaphragm

• the left lung has two lobes

• the right lung has three lobes

• both lungs have two lobes

The respiratory movement representing the total amount of exchangeable air is the

• tidal volume

• inspiratory reserve volume

• expiratory reserve volume

• vital capacity

• dead space volume

What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body
• to bring oxygen to the body
• to break down food and absorb nutrients
• to remove oxygen from the body and deliver carbon dioxide

The two main branches from the trachea (one to each lung)

• bronchi
• alveoli
• capillaries
• bronchioles

The air sacs that are covered with capillaries where gas exchange takes place

• bronchi
• lungs
• oxygen
• alveoli
