Lymphatic System & Immunity
Question | Answer |
---|---|
What is the major difference between lymph and blood plasma? | Amount of proteins present |
The left subclavian vein receives lymph from | Thoracic duct |
The lymph from the right foot empties into the | Thoracic duct |
Function of the spleen? | Removes worn out blood cells |
List 3 physical or chemical barriers | Mucus, Saliva, Urine |
Nonspecific cellular disease resistance mechanism? | Macrophages |
These antimicrobial substances will diffuse to uninfected cells and reduce production of viral proteins. | Interferons |
Sign of inflammation? | Pain, heat, swelling |
Intensifies the effect of interferons and promotes the rate of repair? | Fever |
This induces production of a specific antibody | Antigen |
This cell can only become activated when bound to a foreign antigen while simultaneously receiving a second stimulating signal in a process called co stimulation. | T cell |
Cytotoxic T cells secrete these protein digesting enzymes to trigger apoptosis in an infected cell. | Granzymes |
Cytotoxic T cells secrete this toxin that is used to fragment the DNA of an infected target cell. | Lymphotoxin |
Once activated, a B cell will clone into an antibody secreting cell called a | Plasma cell |
This class of antibodies is mainly found in sweat, tears, breast milk, and gastrointestinal secretions. | IgA |
This class of antibodies is the largest and the first to be produced in an infection. | IgM |
This action makes microbes more susceptible to phagocytosis. | Opsonization |
This is characterized by the inability of the immune system to protect the body from a pathogen. | Immunodeficiency diseases |
An acute allergic response can lead to | Anaphylactic shock |
A natural exposure to an infectious agent leads to | Active immunity |
This class of antibodies indicates a recent invasion. | IgM |
Of the following, which is part of the bodys second line of defense? | Natural killer cells |
Which is the organ with pockets of lymphatic tissue that monitor blood for infectious material? | Spleen |
Where do T cells mature? | Thymus |
