Once you have been exposed to an antigen, you develop immunity against the same antigen because __________.
A
antibodies against the disease are constantly circulating in your blood
B
your innate defenses are strengthened
C
B cells are stimulated to quickly engulf invaders
D
antigens are altered so that the invaders can no longer attack your tissues
E
certain lymphocytes enable the rapid formation of the proper antibodies
검증된 단계별 안내1
Understand the role of the immune system: The immune system is responsible for defending the body against pathogens, such as bacteria, viruses, and other foreign invaders.
Learn about antigens: Antigens are substances that the immune system recognizes as foreign and potentially harmful, prompting an immune response.
Explore the function of lymphocytes: Lymphocytes, including B cells and T cells, are a type of white blood cell that play a crucial role in the adaptive immune response.
Examine the concept of immunological memory: After initial exposure to an antigen, certain lymphocytes, such as memory B cells, remain in the body and enable a faster and more efficient response upon subsequent exposures to the same antigen.
Understand antibody production: When the body is exposed to an antigen again, memory B cells quickly produce antibodies specific to that antigen, providing immunity and preventing the disease from taking hold.
