Roles of the Immune cells

Question 1

Helper T cell

Answer 1

In the bloodstream leukocytes known as helper T cells can chemically recognize the antigen being presented and become activated. Helper T cells turn the immune response from non-specific to antigen-specific, because the identity of the antigen has now been determined. Helper T cells chemically communicate with (activate) the specific B-cell type that is able to produce the antibody needed.

Question 2

Plasma B cell

Answer 2

undergo clonal selection, so several different kinds of antibodies are produced. B-cell type produces the antibody that recognizes the desired antigen.

Question 3

Killer T cell

Answer 3

kill certain cells that were compromised.

Question 4

Macrophages

Answer 4

they are large leukocytes that are able to change their cellular shape to surround an invading cell through the process of phagocytosis. Phagocytes typically contain many lysosome organelles, in order to digest chemically whatever has been engulfed.

Question 5

Antigen-presenting cells

Answer 5

A type of immune cell that boosts immune responses by showing antigens on its surface to other cells of the immune system. An antigen-presenting cell is a type of phagocyte.

Question 6

Memory Cells

Answer 6

Their function is to memorize the characteristics of the antigen that activated their parent B cell during initial infection so when the memory B cell later encounters the same antigen, it triggers an accelerated secondary immune response.
