Adaptive Immune System Flashcards
What are key elements of successful immune defense?
recognition, activation and response
What is the difference between adaptive immunity and innate immunity?
Adaptive immunity is more specialized than innate
What does adaptive immune have the ability to do?
to recognize specific bacteria
Why does the adaptive immune system respond quickly after encountering a microbe?
it remembers prior encounters
Where is the adaptive immune system only present in?
vertebrates
What is the adaptive immune system closely related to?
the circulatory system
Lymphatic organs
organs in which lymphocyte maturation, differentiation and proliferation take place
What are the 2 categories of the lymphatic organs
primary lymphoid organs and secondary lymphoid organs
Primary lymphoid organs
maturation and T&B lymphocytes into antigen-recognizing takes place
What happens when T&B lymphocytes mature
migration occurs from the primary lymphoid organs through the bloodstream to the secondary lymphoid organs
What happens to lymphocytes in secondary lymphoid organs?
they keep diving and differentiate
What occurs in secondary lymphoid organs?
adaptive immune response
What happens when microbes enter the blood in the secondary lymphoid organs?
stimulates an immune response in the spleen
Secondary Lymphoid organs
pathogens and their secreted antigens are trapped, presented to the native lymphocytes that constantly pass through
What are the two fundamental adaptive mechanisms?
cell-mediated immunity and humoral immunity
