Question

1. The specific immune response art 1 of 3 is the second line of defense after anatomical and chemical barriers involves memory of antigens from previous exposure. is the first line of defense in the immune system. involves millions of B and T cells - each individual cell can recognize many different antigens. eBook 2. T cells arise and finish development in the bone marrow. all carry out the same function. are responsible for cell-mediated immunity. make antibodies. 3. Antigens are universal molecules shared by many microbes. are only found inside or on the surface of microbes. are molecules that can be recognized by B- or T-cells. refers to any molecule found inside the body.

Answer 1

QUESTION 1

For a specific response, it is important that our immune system were in contact with the antigen previously. This will promote a memory immune response. This is one of the main goals of vaccine, promotes a memory immune response that is specific for an antigen.

QUESTION 2

T cells are responsible for cell-mediated immunity. AN example of this is the process of cell-mediated immunity is the T cell-mediated cytotoxicity

QUESTION 3

Antigens are molecules that can be recognized by B- or T cells. (also they bind with specific antibodies that recognize an specific portion of the antigen)
