Chapter 2 Immunity
1. Innate immunity, also called natural or native immunity, consists of
mechanisms that respond specifically to:
A) self-cells.
B) microbes.
C) antibodies.
D) inflammation.
2. Adaptive immune responses, also called acquired or specific immunity, are
composed of and their products.
A) granulocytes
B) lymphocytes
C) epithelial cells
D) Toll-like receptors
3. The effector cells of the immune system have the primary function of:
A) activating phagocytic cells.
B) eliminating the antigens.
C) processing antigen into epitopes.
D) controlling the immune response.
, 4. Activation of lymphocytes is dependent upon the and
of the antigens by macrophages.
A) memory; clustering
B) capture; destruction
C) recognition; grouping
D) processing; presentation
5. Major histocompatibility complex (MHC) molecules, with human leukocyte
antigens (HLAs), are markers on all nucleated cells and have an important
role in:
A) identifying blood types.
B) cell membrane transport.
C) suppressing viral replication.
D) avoiding transplant rejections.
6. Dendritic cells, found in skin tissues and lymphoid tissues, are important for:
A) initiation of adaptive immunity.
B) deep-tissue phagocytosis.
C) disposal of dead cells.
D) delaying inflammation.
7. Once T helper cells are activated, they secrete that activate
and regulate nearly all of the other cells of the immune system.
A) complement proteins
B) cytokines
C) leukotrienes
D) bradykinins
