Big Picture: Immunity
Describes the fast, non-specific and first line of defense of our body against any foreign substances or organisms
What is Innate Immune reponse?
These cellular defenses can be distinguished by the number of lobes in their nuclei and the staining properties of their granules.
What are Granulocytes?
These cells are responsible for humoral immunity (extracellular antigens) and are responsible for producing antibodies.
What are B cells?
This provides mucosal immunity (through mucus, tears and saliva), including protection from intestinal tract infection of breast-fed infants
What is IgA?
This portal of entry is the most commonly used by pathogens.
What is respiratory tract?
A collection of molecules of the innate immune system that kill pathogens directly or help phagocytes recognize and kill a pathogen.
What is The Complement System?
This immunity deals with antigens residing within a host cell.
What is Cell-mediated immunity (CMI)?
These immune cells produced antibodies.
What are B cells?
Tearing up during a windstorm would be an example of....
What is the first line of defense?
These circulating substances affect the hypothalamus and initiate fever.
What are pyrogens?
Immunity acquired when a person experience a mild case of influenza after receiving a vaccine
What is Artificial Active Immunity?
This provides the longest-term protection and is transported across the placenta providing protection to the developing fetus
What is IgG?
Specificity and memory are associated with this body defense mechanism.
What is the 3rd line of defense?
Also called the "voices" of the cell, these small proteins produced by cells act as messengers that induce changes such as growth, differentiation, movement, cell death.
What are cytokines?
This type of immunity is acquired by Natalie when she received shots of rabies immune globulin after being bitten by a dog.
What is Artificial Passive Immunity?
In the primary response to an antigen, this is the first class of antibody to be secreted.
What is IgM?
This term is given to any foreign substance that stimulates a specific immune system response.
What is antigen?
This lymphocyte kills cancer cells and virus-infected cells due to their decreased MHC (major histocompatibility cell) receptors.
What is Natural Killer (NK) cell?
This type of T cells has CD4+ receptor in their membranes that help activate other immune cells to fight infection.
What are Helper (or Regulatory) T cells?
The functions in blood of this type of antibody is not well understood but is involved in the development and maturation of antibody response.
What is IgD?
