    Study Notes

    Immune System Cells

    • B cells are responsible for producing antibodies in the immune system.
    • T cells are responsible for cell-mediated immunity, which involves direct killing of infected cells or activation of other immune cells.

    Lymphoid Organs

    • The thymus is the primary site for the production and maturation of T cells in the body.
    • The thymus is a primary lymphoid organ in the immune system.

    Immune System Functions

    • Phagocytic cells, such as neutrophils and macrophages, are responsible for engulfing and digesting pathogens in the immune system.
    • The lymphatic system plays a crucial role in the immune system by helping to defend the body against disease-causing agents.

    Immunity and Immune Response

    • Adaptive immunity can be acquired through vaccination or exposure to an infectious agent, allowing the immune system to remember and respond to specific pathogens.
    • The primary function of the immune system is to protect the body against disease-causing agents, such as pathogens, and to maintain homeostasis.

    Thymus Gland

    • The thymus gland plays a crucial role in the immune system by producing and maturing T cells, which are essential for cell-mediated immunity.
