Adaptive immunity process

Question 1

Starting from the primary lymphoid organ :Thymus

Answer 1

Thymus—>Mature T cells that split in 2. This is cytotoxic T cell and Helper T cell.
Helper T cell just helps cytotoxic T cell.
Cytotoxic T cell forms a clone.

Clone splits into active cytotoxic T cells and Memory cytotoxic T cell.

Active cytotoxic T cell leaves lymphatic tissue to attack invading antigens.

This process is called Cell-mediated immunity

Question 2

Starting from primary lymphoid organ: The red bone marrow

Answer 2

Red bone marrow—> B cells—> helper T cells will help B cells

Then B cell forms a clone. This separates into 2. These are plasmocytes and Memory B cells

Antibodies will bind to an inactivate antigens in bodily fluids

This is known as antibody-mediated immunity which fights again extracellular pathogens.

Question 3

What are ghe different types of cytokines?

Answer 3

-Interleukin-1
-Interleukin-2
