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.
