Ch. 6 Lymphatic System

pertaining to the rupture or destruction of red blood cells

clear, watery fluid containing electrolytes and protein that plays an important part in the lymphatic system; made up of 10% of returning interstitial fluid

leukocytes that are formed in the bone marrow as stem cells; they work together with the immune system to defend the body against antigens

any substance that the body regards as being forward

cells that play an important role in the killing of cancer cells and cells infected by viruses

specialized lymphocytes that produce antibodies

lymphocytes in the thymus that play a central role in cell-mediated immunity

groups of proteins such as interferons and interleukins that are released by the T cells; they act as intracellular signals to begin the immune response

produced in response to the presence of antigens; they activate the immune system, fight viruses by slowing or stopping multiplication, and signals other cells to increase their defenses

aka immune response, involves binding antigens to antibodies

disease fighting proteins created by immune system in response to antigen

antibodies that bind with antigens in antigen-antibody reaction

specialized leukocytes that act as part of the antigen-antibody reaction by destroying foreign substances

type of leukocyte that surrounds and kills invading cells

group of proteins that circulate in the blood in an inactive form

known as swollen glands; an inflammation of the lymph nodes

any disease process affecting the lymph nodes

benign tumor formed by an abnormal collection of lymphatic vessels due to a congenital malformation of the lymphatic system

bleeding from the spleen

abnormal enlargement of the spleen

diagnostic test performed to detect damage or malformations of the lymph vessels

swelling of the tissues due to an abnormal accumulation of lymph fluid within the tissues

occurs when the body’s immune system reacts to a harmless allergen

a substance that produces an allergic reaction in an individual

severe response to an allergen that develops quickly and is considered a medical emergency

medications administered to relieve or prevent the symptoms of an allergy

group of diseases in which the immune system produces antibodies against its own tissues

occurs when the immune response is weaken or not functioning properly

bloodborne infection in which the virus damages or kills the T cells of the immune system

caused by a pathogen that does not normally produce illness in healthy humans; however can produce illness if they are weakened by another condition

the most advanced and fatal stage of an HIV infection

aka biological therapy; disease treatment that involves either stimulating or repressing the immune response

treatment to repress or interfere with the ability of the immune system to respond to stimulation by antigens

medication that kills or damages cells

one-celled microscopic organisms

rod-shaped, spore-forming bacteria

contagious disease that can be transmitted through livestock infected with Bacillus anthracis

small bacterium that lives in lice, fleas, ticks and mites; causes Rocky Mountain Spotty fever

long, slender, spiral-shaped bacteria that have flexible walls and are capable of movement

transmitted to humans through the bite of a tick that has had contact with a deer infected with the spirochete Borrelia burgdorferi.

group of bacteria that resemble clusters of grapes; reside in skin and mucous membranes

bacteria that form a chaina

occurs when antibiotics fail to kill all of the bacteria they target; surviving bacteria become resistant to that drug

fungal infection that develops between the toes; known as athletes’ foot

yeast infection that occurs in skin or mucous membranes

plant or animal that lives on or within another organism at the expense of that organism

caused by parasite that lives in certain mosquitoes and is transferred to humans through infected mosquito bites

parasite that is most commonly transmitted from pets to humans by contact with contaminated animal feces

small infectious agents that live only by invading other cells

highly contagious viral respiratory infection that occurs in seasonal epidemics

acute highly contagious infection that is transmitted by respiratory droplets of the rubeola virus

acute viral infection that is characterized by the swelling of the parotid (salivary) glands

viral infection also known as German measles of 3 day measles; same symptoms of measles but caused by a different virus

acute viral infection that is transmitted to humans though the bite or saliva of infected animal

caused by the herpes virus, Varicella zoster; characterized by fluid filled blisters; aka chickenpox

known as shingles; acute viral infection characterized by painful skin eruptions on an underlying nerve

caused by Epstein-Barr virus, characterized by sore throat, fever, enlarged lymph nodes. known as the kissing disease

medications capable of inhibiting growth or killing pathogenic bacterial microorganisms

substance that causes the death of bacteria

an agent that destroys or inhibits the growth of fungi

used to treat viral diseases or provide temporary immunity

study of the prevention, causes, and treatments of tumors and cancers

abnormal growth of body tissue

not life threatening, although this type of tumor can cause damage as it grows and places pressure

benign tumor made up of muscle tissue

progressively worse and life-threatening that can be spread to distant body sites

malignant tumor derived from muscle tissue

process though tumor supports its growth by creating its own blood supply

form of treatment that disrupts the blood supply to a tumor

uncontrolled division of cells and the ability of these cells to invade other tissues,

process by which cancer is spread to a new site

malignant tumor that occurs in epithelial tissue

malignant tumor in its original position that has not yet disturbed or invaded surrounded tissue

large group of carcinomas derived from the glandular tissues

malignant tumor derived from connective tissue

hard tissue sarcoma that usually involves upper shaft of the long term

process of classifying tumors by how far the disease has progressed

malignancies affecting the lymphoid tissue

cancer of the immune system distinguished by the presence of large, cancerous lymphocytes known as Reed-Sternberg cells.

refers to all lymphomas other than Hodgkin’s lymphoma.

carcinoma that develops from the cells of the breast

breast cancer at its earliest stage before the cancer has broken through the wall of the milk duct.

starts in the milk duct and invades the fatty breast tissue outside the duct.

rare but aggressive form of breast cancer in which the cancer cells block the lymphatic vessels in the skin of the breast.

self-care procedure for the early detection of breast cancer.

radiographic examination of the breasts to detect the presence of tumors or precancerous cells

surgical removal of only the cancerous tissue with the surrounding margin of normal tissue

use of chemical agents and drugs in combinations selected to destroy malignant cells and tissues.

radiation therapy administered at a distance from the body

a type of herpes virus found in most body fluid; silent infection without any signs or symtoms
