Exam 10: The Blood Vessels and Blood Pressure

Viral-blocking enzymes induced by interferon are activated only upon viral invasion of the cell.

The only means by which macrophages can defend against microbial invaders is phagocytosis.

Compare and contrast primary versus secondary immune responses.

____________________ in an infected wound is a collection of phagocytic cells, dead tissue liquefied by enzymes released from the phagocytic cells, and bacteria.

Match the condition, labelled a. through g., with the characteristic. a.serum sickness b.immediate hypersensitivity c.acquired immune deficiency syndrome d.delayed hypersensitivity e.immune-complex disease f.autoimmune disease g.severe combined immunodeficiency -allergic reaction to injection of "borrowed" antibodies that confer passive immunity

Which of the following is NOT a way by which antibodies exert their protective influence?

A carcinogenic factor causes ____________________.

People with type A blood produce anti-B antibodies without ever being exposed to type B blood, but Rh-negative individuals produce anti-Rh antibodies only if they are exposed to Rh-positive blood.

Which of the following is NOT attributable to components of the complement system?

Match the type of immunity, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.) a.applies to active immunity b.applies to passive immunity c.applies to both active and passive immunity -natural immunity is actually a special case of this type of immunity

HLA antigens are found only on the surface of leukocytes.

Antibody proteins consist of two heavy and ____________________ light polypeptide chains.

____________________ is the process by which a substance separates from a solution.

The large intestine's normal microbial population helps defend against infection within the lower intestine.

Match the type of T cell, labelled a. through e., with its characteristics. (Options may be used more than once or not at all.) a.applies to cytotoxic T cells b.applies to helper T cells c.applies to suppressor T cells d.applies to both helper T and suppressor T cells e.applies to all three types of T cells -called regulatory T cells

Diapedesis is the means by which a leukocyte reproduces.

Which of the following is NOT accomplished by antibodies?

A given allergen can activate a B cell or T cell.

Match the condition, labelled a. through g., with the characteristic. a.serum sickness b.immediate hypersensitivity c.acquired immune deficiency syndrome d.delayed hypersensitivity e.immune-complex disease f.autoimmune disease g.severe combined immunodeficiency -located in the "arm" regions of an antibody

____________________ immunity is not self-generated compared to active immunity.
