First Line of Defense: Physical & Chemical Barriers
Study the physical, chemical, and biological barriers that form the body's non-specific innate immune response.
Key Questions
- Explain how the skin and mucous membranes act as crucial physical barriers against pathogens.
- Compare the effectiveness of chemical barriers (e.g., stomach acid) with biological defenses (e.g., microbiota).
- Analyze how disruptions to the first line of defense can increase susceptibility to infection.
