Immunology 3 Flashcards
What do you call the stomach area of a phagocyte
Phagosome
What does antigen mean
A substance that is recognised by the immune system as self or non self and stimulates an immune response
What is an antibody
A blood protein produced in response to, and counteracting a specific antigen
What are the 5 stages and cells involved in the body’s response to an antigen
-use of chemical and physical barriers
-inflammation
-phagocytosis
-action of T cells
-actions of B cells
What is the difference between cell-mediated immunity and antibody mediated immunity
Cell mediated response is associated with T-lymphocytes destroying causative agents without producing antibodies whereas antibody-mediated response is associated with B-lymphocytes destroying causative agents by producing antibodies against it
What is the role of T and B cells in the secondary immune response
They trigger a stronger and more rapid immune response after encountering the same antigen
What are t and b cells
White blood cells in the immune system
What are the 2 types of T cell and their receptors
T-helper (CD4 receptor)
T-killer (CD8 receptor)
Where do T and b cells mature
T cells mature in the thymus
B cells mature in the bone marrow
