Lesson 18 Flashcards
The scientific study of the immune system and immune response
Immunology
Scientist who study various aspects of the immune system
Immunologist
It is considered as the third line of defense
Immune system
It is considered as a specific host defense mechanism because it springs into action to defense against a specific pathogen
Immune system
Understanding immunology boils down to two terms
Antigens
Antibodies
Molecules that stimulate the immune system to produce antibodies
Antigens
Proteins produced by the immune system in response to antigens
Antibodies
Primary function of the immune system
Differentiate between self and non-self
Destroy that which is non-self
Two major arms of immune system
Humoral immunity
CMI (Cell Mediated Immunity)
Always involves the production of antibodies in response to antigens
Humoral Immunity
Involves various type of cells, with antibodies only playing a minor role
Cell Mediated Immunity
Humoral Immunity
B Cells or T Cells?
B Cells
Cell Mediated Immunity
B Cells or T Cells?
T Cells
Hunoral immunity is mediated by antibodies
Antibodies-mediated Immunity
Immunity that results from the active production or receipt of protective antibodies during one’s lifetime
Acquired Immunity
Two types of Acquired Immunity
Active Acquired Immunity
Passive Acquired Immunity
Antibodies that are actually produced within the person’s body
Active Acquired Immunity
Immunity that results from a vaccine
Artificial Active Acquired Immunity
The person receives antibodies that were produced by another person or by more than one person
Passive Acquired Immunity
This acquired immunity is temporary
Passive Acquired Immunity
Acquired by an acquired immunity fetus when it receives antibodies un utero; infant receives colostrum
Natural Passive Acquired Immunity
Acquired when acquired immunity a person receives antibodies contained in antisera or gamma globulin
Artificial Passive Acquired Immunity
Defined as material that can artificially induce immunity to an infectious disease
Vaccine
Deliberately exposes a person to a harmless version of pathogen or toxin
Vaccination
