are antibodies good or bad
good
what is an antigen
proteins used to identify "self" vs. "not-self"
shat do B cells do
produce antibodies
what are the 3 types of T cells
helper, cytotoxic (killer), regulatory
what's a phagocyte
leukocytes (WBC)
what shape is it
Y
what can antigens bind to
antibodies and microbes/viruses
what are the 2 types of B cells
plasma or memory
what do T cells do
a foreign protein that enters the body is an antibody. true or false.
false. antigens
what is an antibody
a protein that's made by the immune system to tag and destroy microbes
who finds "non-self" antigens
macrophages
what do plasma B cells do
reproduce really fast to create antibodies
what do killer/cytotoxic T cells do
look for and destroy bad microbes “tagged” by antibodies
what's the first line of defence against bacteria & viruses (and what's the difference)
skin, mucus, cilia, phagocytes
difference: viruses aren't alive, bacteria is
what binds to antibodies
antigens
what type of cell identifies "non-self" antigens
helper T-cells identify
what do memory B cells do
what do regulatory T cells do
stop the immune response after victory against the bad mcirobe is achieved!!!
the immune response is triggered when...
a macrophage brings an antigen to a helper T cell
what cell produces antibodies
plasma cells (B cell)
what's the purpose of antigens
trigger immune responses
what are B cells (a type of...)
leukocytes (WBC)
what do T cells do when they're presented with an antigen (release... to start...)
release cytokines to start B cell division
what's the role of a fever when you're sick
can destroy many types of viruses and microbes ("cooking them" like we with chicken)
