Answer
The immune system's response to reexposure to the Ebola virus 5 years after the first encounter involves a more rapid and effective response due to immunological memory.
Solution
a
Memory Cells: Upon the first encounter with the Ebola virus, the immune system generates memory B cells and T cells specific to the virus. These cells persist in the body for years
b
Recognition: When reexposed to the Ebola virus, these memory cells quickly recognize the viral antigens
c
Activation: The memory B cells rapidly differentiate into plasma cells that produce specific antibodies against the Ebola virus. Similarly, memory T cells quickly activate and proliferate
d
Response: The presence of pre-existing antibodies and activated T cells leads to a faster and more efficient immune response, often neutralizing the virus before it can cause significant harm
Key Concept
Immunological memory
Explanation
Immunological memory allows the immune system to respond more rapidly and effectively upon reexposure to a previously encountered pathogen, such as the Ebola virus.
