1. Physical barriers: The skin and mucous membranes act as physical barriers to prevent pathogens from entering the body.
2. Inflammation: Inflammation is a natural response to infection or injury, which helps to isolate and destroy pathogens.
3. Fever: A fever is the body's way of raising its temperature to help fight off infections.
4. Phagocytosis: White blood cells called phagocytes engulf and destroy pathogens.
5. Antibodies: Antibodies are proteins produced by the immune system that specifically target and neutralize pathogens.
6. Complement system: The complement system is a group of proteins that work together to enhance the immune response and destroy pathogens.
7. Interferons: Interferons are proteins that help to inhibit the replication of viruses.
8. Natural killer cells: Natural killer cells are a type of white blood cell that can recognize and destroy infected or cancerous cells.
9. T cells: T cells are a type of white blood cell that can directly kill infected cells or help to activate other immune cells.
10. B cells: B cells are a type of white blood cell that produce antibodies to target specific pathogens.
11. Cytokines: Cytokines are signaling molecules that help to regulate the immune response.
12. Memory cells: After an initial infection, the immune system can create memory cells that remember the specific pathogen and mount a faster and more effective response upon re-exposure.
