Study Notes
Immune System Components and Functions
- Cytotoxic T cells are responsible for lysing cells infected by viruses.
- Antibodies, protein substances developed by the body, interact with specific antigens to neutralize threats.
- Bone marrow is the primary site where precursors of all blood cells reside.
- T lymphocytes, specifically cytotoxic T cells, attack foreign invaders (antigens) directly.
Immune Response
- The body's specific protective response to foreign agents or organisms is termed the adaptive immune response.
- B lymphocytes are important for producing a humoral immune response, which involves the secretion of antibodies.
Immunodeficiencies
- Primary immunodeficiencies are caused by genetic factors, while secondary immunodeficiencies result from external factors such as infections or medications.
Autoimmune Conditions
- Autoimmune conditions occur when the immune response mistakenly targets the body’s own tissues, leading to damage.
Immunity Types
- Natural (innate) immunity serves as the first line of defense against pathogens and provides immediate but non-specific protection.
- Leukocytes, or white blood cells, participate in both natural (innate) and acquired (adaptive) immune responses.
Phagocytosis and Cell Mediators
- Mast cells and basophils fight invasion by releasing cell mediators like histamine and by engulfing foreign bodies or toxins.
- Macrophages act as phagocytic cells, ingesting greater numbers of foreign bodies than granulocytes, helping to clear infections effectively.
