Q
Q: What is the function of memory cells in the immune system?
Solution: Memory cells are long-lived cells that remember past infections and enable a faster and more effective response upon re-exposure to the same pathogen.
Steps: 6
Step 1: Understand that the immune system protects the body from infections.
Step 2: Learn that when the body encounters a pathogen (like a virus or bacteria), it creates special cells to fight it.
Step 3: Know that some of these cells become memory cells after the infection is cleared.
Step 4: Realize that memory cells stay in the body for a long time, sometimes for years.
Step 5: When the same pathogen tries to infect the body again, memory cells recognize it quickly.
Step 6: Because of this recognition, the immune system can respond faster and more effectively to fight off the infection.
