Ch 14 Flashcards
(80 cards)
Lymphatic system function transports
Proteins and fluid that have leaked, back into the bloodstream.
Lymphatic vessels
Absorb lipids from intestines and transports them to the bloodstream
Lymphocytes and monocytes protect the body by
Mounting a cellular attack on foreign cells and organs
Lymph nodes
- cervical (neck)
- axillary (armpit)
- mediastinal (chest)
- mesenteric (intestinal)
- paraaortic (lumbar)
- inguinal (groin)
Macrophages
Phagocytose foreign substances
B lymphocytes (B cells)
Produces antibodies; mature in the bone marrow.
T lymphocytes (T cells)
Attack bacteria and foreign cells; originate in the thymus gland. Does not produce antibodies.
Spleen destroys
Red blood cells
Spleen filters
Microorganism’s and other foreign material out of the blood stream.
Spleen activates
Lymphocytes during blood filtration (action is produced in the thymus gland)
Thymus gland provides
Immunity in fetal life and in early years in growth
LEUKOCYTES
Neutrophils, monocytes, and macrophages.
Adaptive immunity (active)
Having infection, vaccination, transfer of immune cells from a doner. Stem cell transplant.
Adaptive immunity (passive)
Antitoxins, immunoglobulin, maternal antibodies
Cytotoxic T cells (T8 cells) attach to and
Directly kill antigens
Dendritic cells are a
Macrophage derived from monocytes.
Dendritic cells recognize
And digest foreign antigens
Vaccines contain
Antigens from the patients tumor cells. Stimulate the patients own at T cells to recognize and kill cancerous cells.
Dendritic cells cultured
And exposed outside the body and reinfused
Monoclonal antibodies (MoAb)
Multiple copies of cells or genes that kill tumor cells
Donor lymphocyte infusions
T cells, infused after allogeneic stem cell or bone marrow transplant, attack tumor.
Adaptive immunity
Ability to recognize and remember specific antigens and mount in attack on them
Adenoids
Mass of lymphatic tissue in the nasopharynx
Antibody
Protein produced by B cells to destroy antigens
