ANSWERS WITH COMPLETE SOLUTIONS GRADED A++
specific host defense
What is adaptive immunity also called?
Adaptive is more specific but could accidentally target ourselves. Adaptive also
has immunological memory so our body saves cells that were successful in
thwarting an attack.
What are the key differences between innate and adaptive immunity?
Because it is not present at birth but develops overtime as the body encounters
and learns to recognize foreign substances
Why is it called an acquired immunity?
immune cells that help start the immune response by showing pieces of the
pathogen to other T-cells
Define professional antigen presenting cells (APCs)?
Dendritic cells, macrophages, and B cells
What are the 3 antigen presenting cells?
throughout the body
Where is dendritic cells found?
lymphoid tissue connective tissue and body cavities
Where are macrophages found?
Lymphoid tissue and blood
, Where are B cells found?
Antigens
What triggers the adaptive immunity system?
Recognize pathogens and produce antibodies
What do B cells do?
Kills cancerous and virus infected cells that are marked for destruction by
antibodies and release cytokines to direct other immune cells
What do T cells do?
A protein tag on a cell used by the body to mark cells as self or outsider
What is an antigen?
Proteins that detect antigens, antibodies match up the shape of the protein tag on
the invaders and flags the cell for destruction
What is an antibody?
Healthy cells make antibodies, help macrophages be good killers, and help the
body regulate the types and intensity of response
What other things do T cells do?
Chemical messengers that signal danger or damage to other immune cells
boosting response
What are cytokines?
Bacterial cell walls, capsules, Pili, flagella, proteins of viruses, fungi and protozoa
What are some examples of antigens?
A normal protein in the immune system that is mistakenly attacked in people with
autoimmune disease
