How does the first line of defense protect the body against pathogens?

∙ 14y ago
The body's three lines of defense against a pathogen (germ) are:
1. Anatomical and physiological barriers-Includes skin, hair, mucous membranes, saliva, tears, stomach acid, pH, temperature.
2. Non-specific response-Includes phagocytosis of pathogen, inflammation of tissues, vasodilation (increased blood flow to area), and swelling.
3. Specific response-antibody production and cell mediated immunity to particular pathogen. Maintained indefinitely.

What are your body's first-line defenses against pathogens in general?
Your skin is the first line of defense.
What are your body' first-line defenses against pathogens in general?
Your skin is the first line of defense.
