Question 3

Antibody

Answer 3

Protein produced by B cells to destroy antigens

Question 6

B Cell (B lymphocyte)

Answer 6

Lymphocytes that matures into a plasma cell to secrete antibodies

Question 7

Cell-mediated immunity

Answer 7

T cells (cytotoxic, helper and suppressor) respond to antigens and destroy them; a type of adaptive immunity

Question 8

Cytokines

Answer 10

Proteins secreted by cytotoxic T cells to aid in antigen destruction. Examples are interferon and interleukins

Question 11

Cytotoxic T cells (CD8+ T cell)

Answer 11

Lymphocytes that directly kills antigens

Question 12

Dendritic cell

Answer 12

Antigen-presenting cell; shows T and B cells what to attack

Question 13

Helper T cell (CD4+ T cell)

Answer 13

Lymphocytes that aids B cells and stimulates T cells

Question 14

Humoral Immunity

Answer 14

B cells produce antibodies after exposure to specific antigens; a type of adaptive immunity

Question 15

Immunity

Answer 15

Body’s ability to resist foreign organisms and toxins that damage tissues and organs. Includes both natural and adaptive

Question 16

Immunoglobulins

Answer 16

Antibodies such as IgA, IgM, IgA, IgD, and Ig E; secreted by plasma cells (mature B cells) in response to the presence of an antigen

Use of immune cells, antibodies, or vaccines to treat or prevent disease

Question 18

Inguinal nodes

Answer 18

Lymph nodes in the groin region

Question 19

Interferons

Answer 19

Proteins (cytokines) secreted by T cells and other cells to aid and regulate the immune response

Question 20

Interleukins

Answer 20

Protein that stimulate the growth and B and T cells

Question 21

Interstitial fluid

Answer 21

Fluid in the spaces between cells; This fluid becomes lymph in lymph capillaries
