-engulf/destroy foreign cells via phagocytosis
-three types: macrophages, neutrophils, dendritic cells
-innate
mast cells - CORRECT ANSWER--white blood cell
-releases histamines (contributor to allergic reactions and inflammation)
-innate
complement system - CORRECT ANSWER--enhances immune function
-certain proteins that circulate the blood in an inactive form
-activated when proteins bind to invading microorganisms
-sets off a biochemical cascade
1. formation of MAC ---> cell lysis
2. opsonization ----> phagocytosis
, 3. cell signaling ----> inflammation
-innate
B cells - CORRECT ANSWER--white blood cell
-expresses antibodies
-differentiate into plasma and memory cells
-mature in bone marrow
-adaptive immunity
T cells - CORRECT ANSWER--white blood cells
-lymphocytes provided by thymus that hunt down and kill pathogens
-mature in thymus
-adaptive immunity
process of inflammation - CORRECT ANSWER-1. bacteria and other pathogens enter wound
2. mast cells release histamine which will allow blood flow to increase (releases heat to wound).
Blood vessels become leaky from histamine release.
3. Dendritic cells release cytokines that bind to and recruit phagocytes to site of injury and flow
into blood vessels
4. Phagocytes that were recruited engulf pathogens by phagocytosis
*this process is innate
antibody - CORRECT ANSWER--a protein found on the surface of a B cell or free floating after
the B cells release them
-responds to an antigen (a protein found on the surface of bacteria)
-antibody will bind to a specific pathogen
