Chp 14- Blood Lymphatic and Immune Flashcards
macrophages
phagocytose foreign substances
B lymphocytes (B cells)
produce antibodies; mature in the bone marrow
T lymphocytes (T cells)
attack bacteria and foreign cells; originate in the thymus gland
natural immunity
resistance present at birth; not dependent on prior exposure to an antigen
adaptive immunity
body’s ability to recognize and remember specific antigens in an immune response
Monoclonal antibodies (MoAb)
multiple copies of cells or genes that kill tumor cells; passive immunotherapy
vaccines
contain antigens from the patients tumor cells; stimulate the patients own T cells to recognize and kill the cancerous cell’s active immunotherapy
(IGNORE)transfer of immune cells
in bone marrow transplantation, T lymphocytes from a donor can replace a patients immune system with new cells that recognize tumor cells as foreign and kill them
adenoids
mass of lymphatic tissue in the nasopharynx
axillary nodes
lymph nodes in the armpit
cell-mediated immunity
T cells that respond to antigens and destroy them
cervical nodes
lymph nodes in the neck region
complement system
proteins in the blood that help antibodies and kill their target
cytokines
proteins secreted by cytotoxic T cells to aid in antigen destruction
cytotoxic T cell (CD8+ T cell)
lymphocyte that directly kills antigen
dendritic cell
antigen-presenting cell; shows T and B cells what to attack
Helper T cell (CD4+ T cell)
lymphocyte that aids B cells and stimulates T cells
humoral immunity
B cells produce antibodies after exposure to specific antigens; type of adaptive immunity
immunoglobulins
antibodies secreted by plasma cells in response to the presence of an antigen
inguinal nodes
lymph nodes in the groin region
interferons
proteins screted by T cells and other cells to aid and regulate the immune response
interleukins
proteins that stimulate the growth of B and T lymphocytes
lymph
thin, watery fluid within lymphatic vessels and collected from tissues throughout the body
lymph capillaries
tiniest lymphatic vessels
lymphoid organs
lymph nodes, spleen, thymus gland
lymph node
collection of stationary solid lymphatic tissue along lymph vessels
lymph vessel
carrier of lymph throughout the body
macrophage
large phagocyte found in lymph nodes and other tissues of the body
mediastinal nodes
lymph nodes in the area between the lungs in the thoracic cavity
mesenteric nodes
lymph nodes in the mesentery
