Lymphatic tissue contains an interlaced network of reticular fibers that functions to

Select one:

• produce lymphocytes.
• produce capsules around lymph nodes.
• attack microorganisms.
• line the walls of lymphatic vessels.
• trap microorganisms.

ANSWERS trap microorganisms When innate immunity is activated,

Select one:

• each exposure is very specific.
• previous exposures are remembered.
• each exposure produces the same response.
• each exposure increases the strength of the immune

response.

• the second exposure does not produce a response.

2:

ANSWERS c. each exposure produces the same response.Which of the following is part of the upper respiratory tract?

Select one:

• lungs
• pharynx
• trachea
• bronchi
• bronchioles

ANSWERS b. pharynx Physiological dead air space is anatomic dead space plus

Select one:

• the residual volume.
• the volume of any alveoli where gas exchange is diminished.
• the volume of blood flowing to the lungs.
• the respiration rate.
• tidal volume.

ANSWERS b. the volume of any alveoli where gas exchange is diminished.For air to flow into or out of the lungs, there must be

Select one:

• a volume gradient established between the atmosphere and

the alveoli.

3:

• a temperature gradient between the atmosphere and the

alveoli.

• a pressure gradient established between the atmosphere

and the alveoli.

• a diffusion gradient between the atmosphere and the

alveoli.

• None of these choices is correct.

ANSWERS c. a pressure gradient established between the atmosphere and the alveoli.Gas exchange between the air in the lungs and the blood takes place in the

Select one:

• alveoli.
• primary bronchi.
• terminal bronchioles.
• trachea.
• respiratory bronchi.

ANSWERS a. alveoli.Which of the following increases the rate of gas exchange across the respiratory membrane?

Select one:

• increased fluid in the alveoli
• increased thickness of the respiratory membrane

4:

• increased surface area of the respiratory membrane
• increased connective tissue in the alveolar wall
• decreased surface area of the respiratory membrane

ANSWERS c. increased surface area of the respiratory membrane As the result of an asthmatic attack,

Select one:

• ventilation exceeds the ability of blood to pick up oxygen.
• ventilation is inadequate to oxygenate blood.
• pulmonary blood flow is reduced while ventilation remains

normal.

• the surface area available for gas exchange increases.
• bronchioles dilate.

ANSWERS b. ventilation is inadequate to oxygenate blood.Indicate the statement that describes respiratory function in a highly trained athlete at maximal exercise.

Select one:

• Unchanged minute ventilation; increased respiratory rate;

decreased vital capacity

• Increased residual volume, respiratory rate; decreased

alveolar ventilation

• Increased tidal volume, unchanged minute ventilation and

alveolar ventilation
