Nonspecific defenses against disease include several mechanisms. These are the body's first line of defense against pathogens and are not specific to any particular disease. They include:

1. Skin: The skin acts as a physical barrier, preventing pathogens from entering the body.

2. Mucous Membranes: These line the body's cavities that are exposed to the external environment and secrete mucus, which can trap pathogens.

3. Cilia: These are tiny hair-like structures in the respiratory tract that can move in coordinated waves to push mucus and trapped pathogens out of the body.

4. Stomach Acid: The highly acidic environment of the stomach can kill many pathogens that are ingested with food.

5. Inflammatory Response: This is a series of events that can destroy pathogens at the site of an infection. It includes the release of chemicals that attract white blood cells to the site, increased blood flow to the area, and increased permeability of blood vessels to allow more immune cells to reach the site.

6. Fever: An elevated body temperature can inhibit the growth of some pathogens and enhance the body's immune responses.

7. Phagocytes: These are white blood cells that can engulf and destroy pathogens.

8. Natural Killer Cells: These are immune cells that can kill virus-infected cells and cancer cells.

9. Complement System: This is a group of proteins in the blood that can help destroy pathogens by poking holes in their cell membranes, making them
