Study Notes

Overview of the Immune System

Provides resistance against microorganisms, including bacteria, fungi, and viruses.

Three Lines of Defense

Surface Barriers
- Acts as the first line of defense.
- Comprises intact skin and mucosal surfaces, designed to prevent pathogen entry.
Innate Internal Defenses
- Serves as the second line of defense.
- Activated when pathogens breach surface barriers.
- Employs inflammation and utilizes antimicrobial proteins and phagocytes to control the spread of invaders.
Adaptive (Specific) Defense System
- Functions as the third line of defense.
- Targets specific pathogens identified as threats.
- Involves a more prolonged response compared to innate defenses, ensuring a tailored attack against known enemies.
