Chapter 24 Part 2 Flashcards
Which lymphoma type is more common, occurs in all age groups, characterized by enlarge spleen, anemia, and general malaise.
Non-Hodgkin disease
Which lymphoma type has 90%-95% cure rate of spotted early? Characterized by painless, enlargement of one or more lymph nodes.
Hodgkin disease
What is the largest single mass of lymphatic tissue in the body? Contains white and red pulp, is most often damaged in cases of abdominal trauma.
Spleen
True or false: no other structure/ organ can adequately take over the functions of the spleen after splenectomy.
False: red bone marrow and liver can take over spleen function
Egg- shaped masses of lymphatic tissue not surrounded by capsule are what? Examples of this?
Lymph nodules, tonsils and aggregated lymphatic follicles
For innate immunity, what is the first line of defense? Prevents invasion of pathogens into interior body.
Barrier: skin and mucous membrane
Innate immunity second line of defense?
Internal defenses: antimicrobial substances, phagocytes, natural killer cells, inflammation, fever
What are the four signs/ symptoms of inflammation?
Redness, heat, swelling, pain
An abnormally high body temperature, commonly occurring during infection and inflammation, happens due to hypothalamic thermostat reset is what?
Fever
Substances that the immune system recognizes as foreign are known as what?
Antigens
Sometimes tissue undergoes changes that cause the adaptive immune system to recognize them as foreign and attack them, thus leads to what kind of condition?
Auto-immune disease
Name the two cell types that originate in red bone marrow that carry out adaptive immune responses
B cells and T cells
Specific proteins that bind to and inactivate specific antigens are known as?
Antibodies
Name the 3 major types of T cells?
Helper T cells, cytotoxic T cells, memory T cells
What type of bat cells are like soldiers that battle with foreign invaders? Their name represents its function: “killing cells”.
Cytotoxic T cells
What type of T cell remains in lymphatic tissues after original infection to more speedily recognize the same antigen if the same antigen should arrive at a later date? This allows for a faster immune reaction than first antigen.
Memory T cells
What type of T cell aids other cells of the adaptive immune system in fighting invaders?
Helper T cells
To reduce rejection risk, what is given to organ donor recipients?
Immunosuppressive drugs
What condition is characterized by an assortment of infections due to progressive destruction of immune system cells in a persons body who has been afflicted by human immunodeficiency virus?
AIDS
What type of cell stays in lymphatic tissues? When activated, these develop into plasma cells, which then secret specific antibodies which inactivate specific antigens.
B cells
The antibody levels during subsequent infections of certain antigens that is far greater and is more intense is a primary or secondary response?
Secondary response
During initial contact with a Specific antigen, antibodies aren’t present for a few days then slowly rise followed by a slow decline is a primary or secondary response?
Primary response
This extreme, sometimes life-threatening allergic reaction to an antigen (allergen) in a hypersensitive person, characterized by airways constriction and shock due to vasodilation and fluid loss from blood.
Anaphylactic shock
During old age the immune system is weaker and..
More prone to infections
