Nonspecific immunity is also referred to as
Innate immunity, native immunity, genetic immunity
A set of nonspecific responses that often occurs in the body
Inflammatory response
Speed of nonspecific immunity
Not specific. Recognizes abnormalities
Speed of nonspecific immunity
Rapid
Memory of nonspecific immunity
None. Same response to all abnormalities
Chemicals of nonspecific immunity
Complement proteins, interferons, others
Nonspecific immunity cells
Phagocytes (neutrophils, macrophages, dendritic cells)
Includes protective mechanisms that confer very specific protection against threat
Specific immunity
Specific immunity is often referred to as
Adaptive or acquired immunity
Specific immunity specificity
Recognizes certain antigens on certain cells or particles
Speed of specific immunity
Several hours to several days
Memory of specific immunity
Yes. Enhanced response to repeated exposures
Chemicals of specific immunity
Antibodies, various signaling chemicals
Cells of specific immunity
Lymphocytes (B and T cells)
Types of specific immunity
Natural, active, passive, artificial
Protein molecules critical to immune system
Antibodies
Antibodies complement
Proteins
Uniquely shaped concave regions of antibodies
Combining sites
The antibody combined with another complementary protein called
An antigen
Another word for humoral
Antibody mediated
What does antibody mediated immunity do?
Change the antigens in a way that prevents them from harming the body
Results of antigen-antibody complex
Affiliation
Series of events initiated that kill the cell that the antigen is attached to
Complement cascade
Sites exposed when a white blood cell attaches to an antigen for the complement cascade
Complement binding sites
