What is the function of memory T cells?
Correct Answer: Memory T cells provide long-term immunity.
- Step 1: Understand that T cells are a type of white blood cell that help the immune system fight infections.
- Step 2: Learn that when the body encounters a pathogen (like a virus or bacteria), T cells respond to help eliminate it.
- Step 3: Know that some T cells become memory T cells after the infection is cleared.
- Step 4: Realize that memory T cells stay in the body for a long time, even after the infection is gone.
- Step 5: Understand that if the same pathogen tries to infect the body again, memory T cells can recognize it quickly.
- Step 6: Learn that memory T cells respond faster and more effectively than regular T cells, providing long-term immunity.
