Question | Answer |
the fluid that surrounds body cells | Interstitial fluid |
clear watery fluid that flows in lymph vessels, collected from tissues throughout the body. | Lymph |
lymphocytes and monocytes | Leukocytes found in lymph system. |
Specialized thin walled vessels through which interstitial fluid flows | lymph capillaries |
clusters of larger lymphatic vessels | lymph nodes |
Functions of the lympatic system | Drainage, absorbtion of lipids and transport to blood, protection from foreign bodies |
The path of the lymphatic system | blood capillaries-interstitial fluid-lymph capillaries- lymph vessels- lymph nodes- lymph vessels- thoracic cavity- thoracic (or lymphatic) duct- large veins. |
begin at the spaces around cells throughout the body. THin walled tubes | Lymph capillaries |
thicker walled tubes , like lymph capillaries, contain valves to allow 1 way flow. | Lymph vessels |
Collections of stationary lymph tissue. produce lymphocytes, filter lymph, trap inflamatory substances or cancerous lesions. | Lymph nodes |
special cells located in the spleen, liver, lungs, and lymph nodes. Phagocyose foreign substances). | macrophages |
specialized lymphocytes present in the nodes, produce antibodies. Formed in the bone marrow, transform into plasma cells to make antibodies. | B lymphocytes (B cells) |
specialized lymphocytes, attack bacteria and foreign cells, by recognizing foreign cell surface proteins, attaching to the cells, poking holes in them, and injecting them with toxic substances | T lymphocytes (T Cells) |
Lymph nodes in the neck | Cervical |
Lymph nodes in the armpit | axillary |
Lymph nodes located between the lungs | mediastinal |
Lymph nodes located near the crease of the crotch | inguinal |
masses of lymph tissue in the back of the throat near the oropharynx | tonsils |
enlarged lymph tissue located in the part of the throat near the nasal passage | adenoids |
Lymph tissue located in the LUQ, near the stomach, destroys old erythrocytes, filters foreign substances from the blood, activates lymphocytes, stores erythrocytes and platelets. | Spleen |
lymphatic tissues located in the upper mediastinum. plays a vital role in bodies ability to fight disease and produce immunity | Thymus Gland |
the acceptance of the body's own antigens | tolerance |
a condition where immune system fights against the body's own cell's | autoimmune disease |
foreign substances or organisms | antigen |
the body's ability to resist foreign organisms and toxins | immune system |
genetic predisposition to illnesses, present in the body at birth | Natural immunity |
primitive lymphocytes that destroy tumor cells and virally infected cells | Natural killer Cells |
immunity received by exposure to a disease, either naturally or via vaccine, which causes production of antibodies against said disease | aquired active immunity |
a substance containing modified pathogens or toxins, used to stimulate immunity to a disease or substance | vaccine |
injection of an immune serum containing antibodies produced in another animal or person, provides this | aquired passive immunity |
an antibody producing cell | plasma cell |
IgA, IgD, IgE, IgG, IgM are examples of these. Secreted by plasma cells in humoral immunity | immunoglobulins |
protein produced by B cell lymphocytes to destroy antigens | Antibody |
immune response involving T lymphocytes; antigens are destroyed by direct action of cells, not by antibodies | Cell-mediated immunity |
T lymphocyte that directly kills foreign cells | cytotoxic T cells |
cell (specialized macrophage) that ingests antigents and presents them to T cells | Dendritic cells |
Lymphocyte that aids B cells in recognizing antigens and stimulating production also known as T4 Cell, or CD4+ cell | Helper T Cell |
immune response in which B cells transform into plasma cells and secrete antibodies | humoral immunity |
Antiviral proteins (cytokines) secreted by T cells; they also stimulate macrophages to ingest bacteria. | interferons |
fluid in the spaces between cells. This fluid becomes lymph when it enters lymph capillaries | insterstitial fluid |
lymph capillaries | tiniest lymphatic vessels |
lymph nodes, spleen, and thymus gland | lymphoid organs |
stationary solid lymphatic tissue along lymph vessels | lymph nodes |
carrier of lymph throughout the body; empty lymph into veins in the upper part of the chest | lymph vessel |
organ near the stomach, produces, stores, eliminates blood cells | spleen |
lymphocyte that inhibits the activity of B and T lymphocytes | suppressor T cell |
Lymphocyte that originates in the bone marrow, but matures in the thymus gland; it acts directly on antigens to destroy them or produce cytokines such as interferons and interleukins that are toxic to antigens. | T cell |
organ in the mediastinum that produces T lymphcytes and aids in immune response | thymus gland |
large lymphatic vessel in the chest that receives lymph from below the diaphragm, and from the left side of the body above the diaphragm; it empties the lymph into veins in the upper chest | thoracic duct |
protection | immuno |
lymph | lympho |
lymph node | lymphadeno |
spleen | spleno |
thymus gland | thymo |
poison | toxo |
again, anew | ana |
between | inter |
syndrome associated w/ immune system suppression, and marked by opportunistic infections, secondary neoplasms, and neurologic problems | AIDS |
Yeast-like fungus, normally present in the mouth, skin, intestinal tract, and vagina, overgrows, causing infection of the mouth (thrush), respiratory tract, and skin | Candidiasis |
Yeast-like fungus causes lung, brain, and blood infections. Pathogen found in pigeon droppings, nesting places, air, water, soil | Cryptococcal infection |
Virus that causes enteritis and retinitis. Found in bodily fluids, such as saliva, semen, cervical secretions, urine, feces, bood, breast milk. Usually only causes disease when immune system is compromised. | Cytomegalovirus infection |
Viral infection causes small blisters on the skin of the lips or nose or on the genitals. Can also cause encephalitis | Herpes Simplex (I & II) |
Herpes Simplex above the waist | Herpes Simplex I |
Herpes Simplex below the waist | Herpes Simplex II |
