Explain 2 forms of the body's immune response to antigens !!
Answers
The immune system is composed of antibodies that form after there are pathogens that enter the body.
the body's immune response to antigens is divided into two types, namely humoral immunity and cellular immunity:
Humoral immunity is an immunity that involves the activity of B cells and antibodies that circulate in the blood and lymph fluid.
When an antigen enters the body for the first time, the dividing B cell will form plasma B cells and B cell reminders. Plasma B cells will produce antibodies that function to bind antigens. thus macrophages will more easily capture and destroy pathogens.
when the same antigen returns to the body, the B cell reminder will recognize it and stimulate plasma B cell formation.
Cellular immunity is an immunity that involves T cells that are responsible for directly attacking cells or tissues of the infected body.
when killer T cells come in contact with antigens on the surface of foreign cells, killer T cells will attack and destroy them by damaging foreign cell membranes.
when the infection has been successfully treated, suppressor T cells will stop the immune response by inhibiting the activity of killer T cells and limiting antibody production.
