Flashcards in Chapter Three - Immune System Deck (85)
What are the three mechanisms of protection of the immune system?
Surface protection, acute inflammation, immune response
Surface protection is an example of what kind of immunity?
Acute inflammation is what kind of immunity?
The non-specific process where neutrophils, macrophages, and eosinophils move into an area and complement complex is presented is what mechanism of the immune system?
What is the mechanism of the immune system primarily used by the epithelium and its cells?
What are the two types of adaptive immunity?
Humoral (B cell) immunity and cell mediated immunity
Humoral immunity is usually in response to what kind of invasion?
What mediates humoral immunity?
B cells and plasma cells with T cell involvement
What type of adaptive immunity involves antibody production?
Humoral (B cell) immunity
Cell mediated immunity is usually a response to what kind of invasion?
Viruses, fungi, or foreign cells
What mediates cell mediated immunity?
Does cell mediated immunity depend on B lymphocytes?
Which type of adaptive immunity is a cytotoxic response?
Cell mediated immunity
What are the functions of the immune system?
Storage of lymphocytes, increase the numbers of lymphocytes, provide a favorable environment for establishing immunity
Humoral immunity and having an incomplete capsule or not one at all are characteristics of what kind of component of the immune system?
Both humoral and cell-mediated immunities along with the presence of a capsule are characteristics of what component of the immune system?
The bone marrow and thymus are examples of which lymphoid organs?
What type of lymphoid organs provides an environment where lymphocytes become immunocompetent?
What kind of lymphoid organ provides an environment where lymphocytes can contact foreign antigens and can interact with each other?
Large amounts of which antibodies are associated with lymph nodules?
IgG or IgA
What is MALT?
Mucosal-Associated Lymphatic Tissue
What kind of lymphatics are located within the GI, respiratory, and urogenital tracts?
The spleen and lymph nodes are examples of what kind of lymphoid organs?
What occurs in the lymph nodules?
B cells dividing to form B memory cells and plasma cells
Secretory IgA is secreted onto what surfaces?
Where can we find secretory IgA?
In or on tears, saliva, gut lumen, nasal cavity, and vaginal surface
What are the functions of IgA?
Neutralize viruses and bacteria toxins, decrease microbial adhesion to cells
What subcategory of MALT is in the GI tract?
GALT (gut-associated lymphatic tissue)
Peyer's patches are located where?
