Immune Basics
This type of immunity is non-specific and responds rapidly.
What is Innate immunity?
A physical barrier that prevents pathogen entry.
What is skin?
One cardinal sign of inflammation involving increased temperature.
What is heat?
Process of engulfing pathogens.
What is phagocytosis?
Cells responsible for antibody production.
What are B-cells?
This type of immunity is specific and has memory.
What is Adaptive Immunity?
These trap pathogens entering body openings.
What are mucus membranes?
Movement of WBCs toward chemical signals.
What is chemotaxis?
First step of phagocytosis.
What is attachment?
Cells that target infected/abnormal cells.
What are T-cells?
A disease-causing agent.
What is a pathogen?
Broad-spectrum antimicrobial proteins in innate immunity.
What are defensins?
Process of WBCs squeezing through blood vessels.
What is transmigration?
Structure formed when pathogen is engulfed.
What is a phagosome?
B-cells become these to produce antibodies.
What are plasma cells?
Part of a pathogen that triggers an immune response.
What is an antigen?
Enzyme found in saliva and tears that destroys bacteria.
What is lysozyme?
Movement of WBCs toward blood vessel wall before leaving vessel.
What is margination?
Structure formed when lysosome fuses with phagosome.
What is a phagolysosome?
These allow faster response to future infections.
What are memory B-cells?
These two cell types make up adaptive immunity.
What are B-cells and T-cells?
Systemic increase in temperature caused by pyrogens.
What is fever?
Purpose of inflammation in preventing pathogen spread.
What is localization of damage?
Final step of phagocytosis removing debris.
What is exocytosis?
Adaptive immunity characteristic absent in innate immunity.
What is memory?
