Four barriers that protect humans from pathogens include the mucus of the upper respiratory system, the acid mantle of the skin, the stomach acid in the digestive system, and the cervical mucus of the female reproductive system. There are also celular barriers via the immune system that prevent infection.

It does this by identifying and destroying these invaders to help keep the body healthy.
What do white blood cells have to do with pathogens?
White blood cells are a critical part of the body's immune system and help to defend against pathogens such as bacteria, viruses, and other harmful invaders. They work by identifying and destroying these pathogens through various mechanisms, including engulfing them, producing antibodies, and coordinating immune responses.
What are the two levels of defense that humans have against patghogens what do their names mean?
Humans have two levels of defense against pathogens: the innate immune system and the adaptive immune system. The innate immune system provides immediate, non-specific responses to a wide range of pathogens, acting as the body's first line of defense. In contrast, the adaptive immune system is specific and develops a targeted response to particular pathogens, including the formation of memory cells for long-term immunity. Together, these systems help protect the body from infections and diseases.
What is an organism that carriers and transmits pathogens to humans or other animals?
Vector.
Why is it healthy for humans to eat fat?

What are the major reservoirs of pathogens?
