A bacteria, virus, or microorganism that can cause disease are referred to as this.
What is a pathogen?
The location of a clotting response.
What is the skin?
Name three surface barriers.
What are skin, mucous membranes, gastric Juices/acids, tears, and saliva?
These are the two types of lymphocytes.
What are B cells and T cells?
This lymphocyte type divides into plasma cells that are identical in function.
What are B-cells?
HIV binds to receptors on _________.
What are T cells?
What are the skin and stomach?
Cell involved in the clotting cascade.
What are platelets?
These provoke immune responses.
What are antigens?
These hunt down and and kill infected cells.
What are Killer/Cytotoxic T Cells?
Artificial immunity is built by the administration of this.
What are vaccines?
Where b cells remain and mature.
What is the bone marrow?
This defense engulfs and destroys pathogens that break surface.
What are phagocytes?
These allow the immune system to mount a stronger defense after initial exposure.
What are memory B cells?
These cells recognize the antigens on macrophages that recently engulfed a pathogen.
What are helper T cells?
What is the central dogma of biology?
DNA --> RNA --> proteins
This organ accepts immature T-cells and then trains them into mature cells that attack pathogens.
What is the thymus?
This protein is an important part of the clotting response.
What are fibrin and thrombin?
These are released by helper T cells to activate B cells and killer T cells.
What are cytokines?
These are cells in the cell mediated immune response that trigger the humoral response.
What are helper T cells?
The enzyme that retroviruses utilize to convert RNA to DNA.
What is reverse transcriptase?
This group of cells that lyse and kill infected body cells.
What are Natural Killer (NK) cells?
These release antigen specific proteins during an immune response.
What are plasma B cells?
Helper T cells “pick up” foreign antigens from macrophages and deliver these antigens to the B cells. The B cells become activated and begin to manufacture antibodies. Helper T cells get these foreign antigens from __________.
What are antigen presenting cells?
