Chpt 16 Quiz 1

What is one function of lymph?

• Transport of foreign particles to the lymph nodes.

• Return of proteins to the tissue fluid.

• Transport of foreign particles to the kidneys.

• Transport of oxygen and carbon dioxide.

Following a tissue transplant, the transplant recipients typically need to take medications to__________.

• suppress their immune system

• prevent blood clots from forming

• stimulate their immune system

• raise their blood pressure

As a result of an allergen binding to an IgE antibody, mast cells release histamine.

• True

• False

What role does the lymphatic system have in influencing body fluids?

• It moves tissue fluid from one area to another, ensuring that all tissue fluid levels are consistent.

• It moves excess tissue fluid from the interstitium to the bloodstream.

• It provides the fluid needed to bathe tissue cells in nutrient-rich fluid.

• It adds hypotonic fluid to any tissue fluid that has an elevated solute concentration.

Viral infections such as mononucleosis, bacterial infections such as tuberculosis and parasite infections such as malaria can stress the immune system and result in overproduction antibodies and immune cells. As a consequence, which organ could experience an increase in size?

• Thymus gland

• Pharyngeal tonsil

• Cervical lymph nodes

• Spleen

The thymus enlarges after puberty.

• True

• False

What occurs during a primary immune response?

• The plasma antibody concentration increases rapidly with maximal levels occurring at about 1-2 days after exposure. Concentration drops off quickly at about day 5.

• The plasma antibody concentration increases rapidly with maximal levels occurring at about 1-2 days after exposure. Concentration remains high for prolonged period.

• The plasma antibody concentration increases slowly, peaking at about 10-12 days after exposure to antigen.

• The plasma antibody concentration increases gradually, continually increasing until about 2 months after antigen exposure, when antibody levels begins to drop.

When does aging of the lymphatic system begin?

• Shortly after birth

• Before birth

• After age 50

• At birth

What is the effect of interleukin-1 secretion?

• An allergic response

• An antibody response

• Cytokine secretion

• Fever

How does a vaccine produce its effects?

• By using chemotaxis to attract antigens to areas where the vaccine can destroy them.

• By directly binding to the antigens and neutralizing them.

• By activating autoantibodies.

• By stimulating a primary immune response.
