Immune System Insights

The immune system features a remarkable structure, consisting of three primary lines of defense. The first is a physical barrier, including skin and mucosal linings, which protects the body from external threats. If invaders breach this barrier, the innate immune system responds with a generalized attack, while the adaptive immune system tailors a specific response to combat particular pathogens. Understanding these mechanisms reveals the elegance and complexity of our body's defenses.
