plasma cells produce

antibodies

which of the following is NOT a nonspecific defense mechanism

antibodies

once a B cell has been activated by a specific antigen (an antigen binds to an antigen receptor on the B cell membrane), it will divide, making many copies of itself. This process is known as.

clonal selection

which of the following is not the major group of lymph nodes?

cervical, axillary, inguinal

the thymus is larger in adults or children?

children

which type of antibody found in breast milk, saliva, and other body secretions?

lgA

which type of antibody is involved in causing immediate allergic reactions?

lgE

an immediate allergic response is caused by

lgE and mast cell releasing histamine

am immediate allergic response that occurs when an allergen enters the blood stream is called

lgE mediated response

which type of the antibody is the main one in circulation?

lgG

which type of antibody is the first one made by a new born and generally the first one to combat the infection?

lgM

which of the following has a connective tissue capsule that encloses the lymphatic tissue?

lymph nodes

normal occuring bacteria live in

mouth, intestine

what is meant by auto immune disease

A disease in which the body's immune system attacks healthy cells.

which of the following is NOT true of antibodies?

Antibodies are produced by B lymphocytes, not T lymphocytes

which of the following is is NOT an action of antibodies with antigens?

Antigen stimulates immune system to make Amati bodies

which of the following produce antibodies?

B cells

which of the following cells are found in lymph nodes?

B lymphocytes

what type of immune cell reaches maturity in the thymus?

T lymph

sspecific

The immune system is the third line of defense. It consists of mechanisms and agents that target specific antigens (Ags). An antigen is any molecule, usually a protein or polysaccharide, that can be identified as foreign (nonself) or self (such as MHC antigens described below).

T cells are responsible for what type of immunity?

cell mediated

which of the following is not the chemical barrier that helps prevents entry of microbes into the body tissue?

acids, lysosomes, mucus, lacrimal fluid, sebum etc

as a child, you received an MMR immunization against measles, mumps, and rubella what kind of immunity do u have?

active

in which case does the recipient start making antibodies to the specific disease? active/ passive

active

a vaccine contains

antigens

antibodies bind to?

antigens

portions of bacteria, viruses, molds, parasites, and cancer cells that cause specific responses from the immune system are called?

antigens

what autoimmune disease effects the joints?

arthiritus

a child is bitten by a rabid dog. he is given a series of injections to fight the rabies infection.

artificial passsive

what is the function of the lymphatic system

balances fluid, absorbs fat, defense

which of the following is NOT true of human MHC proteins?

binds w/ an antigen to make helper t

lymphoma

cancer of the lymphatic tissue

which of the following is NOT an opportunistic disease that is generally causes death for an aids patient?

cd4 count of 200

apoptosis is?

cell death

pus consists of

dead leukocytes (white blood cells) from the body's immune system in response to infection

complement function are

destroy foreign substances

what does bone marrow do

divides red and white blood cells

what is considered Active immunity?

exposed to the pathogen lively, antibodies are made in the body

interferon is a defense against

fever

interferon does what

fight viral diseases

HIV 1 infects what specific T cell?

helper T cell

which of the following is NOT true of a category A stage of an HIV infection?

helper T count is 50 per mm or greater

------- , released by damaged tissue and mast cells, causes capillaries to dilate and become more permeable.

histamine

antibody mediated immunity is also known as?

humoral

the ability of body to react to the antigens and remain free of disease?

immunity

which of the following is a form of nonspecific defense

include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. These barriers are aided by various antimicrobial chemicals in tissue and fluids.

lymphadentis

inflammation of the lymph nodes

lymphagitis

inflammation of the walls of the lymphatic vessels

HIV 1 is transmitted by?

interaction w/ other who has it

special lymphatic capillaries in the small intestine

lacteal

lymphatic system vessel begins with what vessel

lymphatic capillaries

T cells and B cells are what type of cells?

lymphatic cells

which lymphatic structure enters the sub clavian vien

lymphatic ducts

the tonsils are composed of?

lymphatic nodules

the white pulp of spleen contains?

lymphocytes

an antigen presenting cell APC is what type of cell?

macrophage

what happens after a T cell has been activated for a specific antigen?

makes cytokines and clones

B cells are responsible for making

mediated immunity

during clonal selection, most B cells become plasma cells, but other will become.

memory cells

what type of cells allow for long term protection against antigen?

memory cells

what nonspecific cells kill virus infected cells and tumor cells by cell to cell contract

natural killer cells

a mother who had the measles as a child. has a baby. at the age of 1 month , the baby is exposed to measles but does not get sick. what kind of immunity.?

passive

as a child, you had the chicken pox. you are exposed to chicken pox several year years later, but you do not get them again. what kind of immunity do u have? active/ passive

passive

which molecule from a cytotoxic T cells create holes in plasma membrane of virus infected or cancer cells?

perforin

what specific process has been occuring if pus is present around the infected area?

phagocytosis

plasma cell

what is make up of lymph?

protiens, salts, glucose and fats
