    Study Notes

    The Immune System

    • The immune system is a complex response triggered when a foreign substance (antigen) enters the body.
    • The response involves specialized white blood cells called lymphocytes, which are classified into B lymphocytes and T lymphocytes.
    • B lymphocytes mature in the bone marrow and produce antibodies.
    • T lymphocytes mature in the thymus and include helper T cells, cytotoxic T cells, and suppressor T cells.
    • Helper T cells activate B lymphocytes and assist in other immune responses.
    • Cytotoxic T cells directly attack and destroy infected cells.
    • Suppressor T cells regulate the immune response, preventing excessive reactions.
    • Antigen is a foreign substance capable of triggering an immune response.
    • Antibodies are proteins produced by B lymphocytes that specifically bind to antigens.
    • The immune system produces a primary response when exposed to a disease-causing agent for the first time.
    • Memory lymphocytes provide immunological memory, allowing the body to mount a faster and more effective secondary response upon subsequent exposure to the same agent.
    • Active immunity is acquired through exposure to a disease or vaccination.
    • Passive immunity is acquired through the transfer of antibodies from another organism.
    • Vaccines introduce inactive toxins or dead/weakened antigens into the body, triggering an immune response without causing illness.

    Blood Sugar and Diabetes

    • Individuals with diabetes have high levels of glucose in their blood (hyperglycemia).
    • Diabetes can be diagnosed by measuring the amount of glucose in the blood through a blood test.
    • Blood glucose levels can be measured through a rapid finger prick test or a laboratory analysis of a blood sample.
