Study Notes
### Innate Immunity
- Present at birth, offering immediate defense against pathogens.
- Responds rapidly, acting as the body's first line of defense.
Adaptive Immunity
- Develops over time through exposure to specific pathogens.
- Offers a more tailored and targeted immune response.
- Characterized by its specificity and memory.
- Involves the immune system's ability to "remember" past encounters with pathogens.
Phagocytosis
- A process where immune cells engulf and destroy foreign invaders.
- The steps include chemotaxis, adherence, ingestion, digestion, and discharge.
### Inflammation
- A localized reaction to injury or infection.
- Characterized by redness, swelling, heat, and pain.
- Helps to isolate and eliminate harmful substances from the body.
- The stages include the vascular stage and cellular stage.
### Immune System
- A complex network of organs, cells, and proteins that protect the body against pathogens.
- Composed of innate and adaptive immunity systems.
- Includes the lymphatic system, complement system, spleen, thymus, bone marrow and white blood cells.
### Lymphocytes
- Specialized white blood cells critical to the immune response.
- B cells and T cells are the two main types of lymphocytes.
B Cells
- Differentiate into plasma cells, responsible for producing antibodies.
- Provide humoral immunity, which targets extracellular pathogens.
T Cells
- Responsible for cell-mediated immunity, targeting intracellular pathogens.
- Mature in the thymus and recognize antigens processed by phagocytic cells.
Immunity
- The ability to resist disease.
- A combination of innate and adaptive immune responses.
Susceptibility
- Lack of resistance to a disease.
- Individuals with compromised immune systems are more susceptible to illness.
### Hematopoiesis
- The process of blood cell formation.
- Occurs in the bone marrow.
### Dual Nature of Adaptive Immunity
- Characterized by two main components: humoral immunity and cell-mediated immunity.
- Humoral immunity relies on antibodies, while cell-mediated immunity relies on specialized T cells.
- Both components aim to eradicate pathogens in different ways.
Sebum
- An oily substance secreted by the skin’s sebaceous glands.
- Provides a protective barrier against pathogens.
Normal Body Temperature
- Approximately 37°C.
- A temperature of 38°C or higher indicates an abnormal condition.
### Eusinophils
- White blood cells that fight parasites.
- Also involved in allergic reactions.
### Monocytes
- Large white blood cells that mature into macrophages.
- Macrophages phagocytize pathogens and cellular debris.
