Left atria to left ventricle thru what?

• Tricuspid

• Bicuspid or mitral valve

In an activated lymphocyte, it produces two types of daughter cells which one has long-lived cells that retain the ability to start dividing on short notice if antigen is presented to immune cells again at a later date

• Effector cells

• memory cells

• Clonal deletion

• clonal selection

In an activated lymphocyte it produces two types of daughter cells, which one carrys out the attack on the antigen bearing pathogen (B cells produce antibody, T cells release cytokines and destroy antigen bearing cells)

• Clonal deletion

• clonal selection

• effector cells

• memory cells

method by which self-reactive T or B cells are removed during immune system development so that they cannot damage self tissues is what ?

• Clonal deletion

• clonal selection

• effector cells

• memory cells

antigen binding will select for and cause proliferation of T and B cells specific to antigens that are recognized during infection is what?

• Clonal selection

• Clonal deletion

• Effector cells

• memory cells

Out of the 4 key traits of the specific immune system, which one has :

* immune system can remember a pathogen after encountering it once

* Will allow for a faster response time in subsequent exposures

*The basis for vaccines

• Diversity

• Immunologic memory

• distinguish self from non-self

• specificity

Out of the 4 key traits of the specific immune system, which one has antigenic determinants from pathogens or foreign substances will activate specific immune cells

• Diversity

• Immunologic memory

• Specificity

• Distinguish self from non-self

Out of the 4 key traits of the immune system, which one has the immune system to know what is self and not attack or become activated by these determinants

• Specificity

• Distinguish self from non-self

• Diversity

• Immunologic memory

out of the 4 key traits of specific immune system, which one has :

* T cells and B cells will develop reactivity to specific proteins and pathogenic components during every infection - antigens

* T cells and antibodies produced by B cells recognize antigens – cellular determinants on the pathogen of foreign substance

• Specificity

• Distinguish self from non-self

• Diversity

• Immunologic memory

(Adaptive (specific) Immune cells)
