Study Notes
Immunology Terms
- Pathogens are microorganisms that can cause disease.
- Nonspecific defense refers to the body's general defense mechanisms that do not target specific pathogens.
- Macrophages are large white blood cells that engulf and digest pathogens and cellular debris.
- Specific defense is the immune response that targets specific pathogens.
- Helper T cells are a type of T cell that helps activate other immune cells.
- Cell-mediated response is an immune response that involves the activation of T cells.
- Antibody-mediated response is an immune response that involves the production of antibodies by B cells.
- Vaccines are substances that stimulate the immune system to provide immunity against specific diseases.
- Blood type is a classification of blood based on the presence of specific antigens and antibodies.
- The Rhesus (Rh) factor is a specific antigen that can affect blood transfusion compatibility.
- Allergies are immune responses to substances that are typically harmless.
- Autoimmune diseases are conditions where the immune system attacks the body's own cells.
- Antibodies are proteins produced by B cells that specifically target pathogens.
- Antigens are substances that induce an immune response.
- B cells are lymphocytes that produce antibodies.
- White blood cells are cells of the immune system that help fight infections.
- Killer T cells are T cells that destroy infected or cancerous cells.
- Memory cells are long-lived immune cells that remember past infections.
Other Biological Terms
- Food provides nutritional support for the body.
- Proteins are organic compounds made of amino acids that perform various functions in the body.
- Lipids are organic compounds that are insoluble in water and include fats and oils.
