Definitions
This is the development of resistance to disease-causing pathogens.
What is immunity?
This is the first line of defense and includes skin and keratin.
What are physical barriers?
Inflammation is triggered when tissue is this.
What is injured or infected?
This is the process of recruiting cells to an injury site.
What is leukocytosis?
This process is the ingestion and elimination of pathogens.
What is phagocytosis?
This term describes a disease-causing agent such as bacteria or viruses.
What is a pathogen?
This immune system responds quickly (within hours).
What is innate immunity?
This is the goal of inflammation that keeps damage localized.
What is preventing the spread of damaging agents?
This step involves rolling and adherence of cells.
What is margination?
This structure forms to engulf the pathogen.
What is a phagosome?
This refers to a part of a pathogen that triggers an immune response.
What is an antigen?
This immune response takes 5–6 days due to lack of memory.
What is adaptive immunity?
This inflammation goal removes debris and pathogens.
What is disposal of cellular debris?
This is when cells squeeze through the endothelium.
What is transmigration?
This organelle breaks down engulfed material.
What is a lysosome?
Name two examples of pathogens.
What are bacteria, viruses, fungi, protozoa, or parasitic worms?
These cells produce antibodies.
What are B-cells?
Name all 5 cardinal signs of inflammation.
What are pain, redness, impairment, swelling, and heat (PRISH)?
This is the chemical signal that directs cell movement.
What is chemotaxis?
This structure forms when the phagosome merges with a lysosome.
What is a phagolysosome?
This explains why some diseases affect certain species but not others.
What is antigen specificity?
These cells specifically target infected cells.
What are T-cells?
This sign refers to localized temperature increase.
What is heat?
This is programmed cell death.
What is apoptosis?
This is the final step where materials are expelled.
What is exocytosis?
