Mass of lymphatic tissue in the nasopharynx

Protein produced by B cells to destroy antigens

Substance that the body recognizes as foreign; evokes an immune response

Lymph nodes in the armpit

Lymphocyte that matures into a plasma cell to secrete antibodies

T cells that respond to antigens and destroy them

Lymph nodes in the neck region

Proteins in the blood that help antibodies and kill their target

Proteins secreted by cytotoxic T cells to aid in antigen destruction

Lymphocyte that directly kills antigens

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

Lymphocyte that aids B cells and stimulates T cells

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

Body’s ability to resist foreign organisms and toxins that damage tissues and organs

Antibodies secreted by plasma cells in response to the presence of an antigen

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

Lymph nodes in the groin region

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

Proteins that stimulate the growth of B and T lymphocytes

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

• Thin, watery fluid within lymphatic vessels and collected from tissues throughout the

Vessel in the chest that drains lymph from the upper right part of body; empties into large neck vein

Organ in the left upper quadrant of the abdomen that destroys worn-out RBCs, activates lymphocytes, and stores blood

Lymphocyte that inhibits the activity of B and T cells

• Lymphocyte that acts directly on antigens to destroy them or produces chemicals toxic to

Masses of lymphatic tissue in back of the oropharynx

Poison; a protein produced by certain bacteria, animals, or plants

• Exposure of an individual to an antigen that provokes an immune response that will
