Chapter Three - Immune System Flashcards
Surface protection is an example of what kind of immunity?
Innate
What are the three mechanisms of protection of the immune system?
Surface protection, acute inflammation, immune response
Acute inflammation is what kind of immunity?
Innate
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?
Acute inflammation
What is the mechanism of the immune system primarily used by the epithelium and its cells?
Surface protection
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?
Bacterial
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?
T lymphocytes
Does cell mediated immunity depend on B lymphocytes?
No
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?
Diffuse lymphatics
Both humoral and cell-mediated immunities along with the presence of a capsule are characteristics of what component of the immune system?
Lymphoid organs
The bone marrow and thymus are examples of which lymphoid organs?
Primary
What type of lymphoid organs provides an environment where lymphocytes become immunocompetent?
Primary
What kind of lymphoid organ provides an environment where lymphocytes can contact foreign antigens and can interact with each other?
Secondary
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?
Diffuse lymphatics
The spleen and lymph nodes are examples of what kind of lymphoid organs?
Secondary
What occurs in the lymph nodules?
B cells dividing to form B memory cells and plasma cells
