Answer bone marrow, thymus gland, spleen, tonsils, adenoids, and appendix
- neutrophils
Answer white blood cells that is the most abundant and first to travel to the site of infection
- monocytes
Answer become macrophages in body tissues
largest monocyte and their functions include phagocytosis, antigen presentation, and cytokine production
- eosinophils
Answer white blood cells that combat multicellular parasites
- basophils
Answer largest and least common granulocyte, they are responsible for inflammatory reactions during immune response,as well as in the formation of acute and chronic allergic diseases including anaphylaxis, asthma, atopic dermatitis and hay fever.
They perform phagocytosis, produce histamine and serotonin that induce inflammation, and produce heparin that prevents blood clotting.
- mast cells
Answer 1 / 3
granulocyte rich in heparin and histamine
have role in allergies and anaphylaxis similar functions to basophils
- B lymphocytes
Answer become plasma or memory B cells. encounter and engulf an antigen, interacts with helper T lymphocytes, begins producing identical copies of a specific antigen.
Antibodies are secreted from B lymphocytes.
- T lymphocytes
Answer mature in the thymus gland.
Helper T, Cytotoxic killer T, Memory T cells
- Helper T cells
Answer activate cytotoxic T cells and macrophages
- Cytotoxic killer T cells
Answer destroy virus infected cells and tumor cells
- MemoryT Cells
Answer store information about previous infections so antigens can be produced more quickly and in greater numbers in the same infection happens again
- Natural Killer cells
Answer 2 / 3
respond quickly to virus infected or tumor cells
- adaptive immune system
Answer composed of highly specialized cells (B & T lymphocytes) that are activated by exposure to pathogens, and uses an immunological memory to learn about pathogens and enhance the immune response accordingly
- innate immune system
Answer nonspecific, inborn immunity
skin is the first natural barrier against infection
in the GI tract peristalsis, gastric acid and digestive enzymes help remove infectious agents lungs have cilia that move irritant out
- inflammation is an
Answer innate, nonspecific response to a pathogen
- five cardinal signs of inflammation
Answer pain redness
swelling heat loss of function
- immunocompromise
