Skin, mucus, hair, etc.
The body has a number of natural barriers, your skin, your eyelashes, mucus and even tears are all natural barriers to name but a few.
Your body, inside and out is covered by microoranisms. You have about three pound of microbes and that is 10X the number of body cells.
The body's natural barriers include the skin, mucous membranes in the respiratory and digestive tracts, stomach acid, and the immune system. These barriers help protect the body from pathogens and foreign substances, preventing infections and maintaining overall health.
There are multiple chemical barriers present in the body. The sebum of the skin, the lactimal secretions of the eye, the gastric acid of the stomach and the urinary acids of the urinary bladder are all examples of chemical barriers to infection.
The main line of defense in the human body is the immune system, which helps to protect against pathogens such as bacteria, viruses, and parasites. This includes physical barriers like the skin, as well as specialized cells and proteins that work together to identify and neutralize harmful invaders.
When a pathogen enters the body, it first encounters the body's physical and chemical barriers, primarily the skin and mucous membranes. These barriers provide a first line of defense by preventing the pathogen from entering deeper tissues. If the pathogen breaches these surfaces, it then encounters immune cells and proteins in the innate immune system, which act quickly to identify and combat the invader.
The immune system and the lymphatic system work together to protect the body from pathogens. The immune system recognizes and targets pathogens, while the lymphatic system helps circulate immune cells and remove pathogens from the body. Additionally, the skin and mucous membranes act as physical barriers to prevent pathogens from entering the body.
White blood cells, also known as leukocytes, are the blood cells that protect the body from diseases. They are part of the immune system and work to identify and destroy pathogens such as bacteria, viruses, and other harmful substances.
Antigens do not protect the body from disease. Antibodies protect the body from many diseases.

The immune system protects the body by removing bacteria and foreign bodies through mechanisms such as white blood cells, antibodies, and inflammation. These components work together to identify and eliminate pathogens that may cause harm to the body.
Antibodies are proteins manufactured by the body's immune system in response to an invasion by foreign substances such as bacteria or viruses. Antibodies help to identify and neutralize these harmful pathogens, protecting the body from disease.
