    Study Notes

    The Immune System and B Cells

    • The immune system is the body's built-in defense against germs like bacteria, viruses, and fungi that can make us sick.
    • B cells are a specific type of white blood cell that act as soldiers in the immune system, responsible for recognizing and defeating invaders.

    How B Cells Work

    • B cells circulate through the bloodstream, looking for anything that doesn't belong, and recognize the body's own cells as friendly.
    • B cells memorize the appearance of foreign invaders and produce a protein called an antibody to defeat them.
    • Antibodies are Y-shaped proteins that can bind to and neutralize invaders.

    Antibodies and Memory

    • Once a B cell has recognized an invader and produced antibodies, it remembers the invader's appearance forever.
    • This means the body can fight off that specific invader for the rest of its life.

    Vaccination

    • A vaccination is an injection of fake invaders that have been made harmless on the inside but still look like the real invader on the outside.
    • When a vaccination enters the bloodstream, B cells recognize the invaders and start making antibodies to neutralize them.
    • As a result, the body builds up a defense against the real invader, and if it ever tries to enter the body, the B cells are prepared to defeat it.
