The Three Lines of Defense Against Pathogens | Biology

Let's dive into the fascinating world of immunity! Our bodies have three lines of defense against infections and diseases. The first line of defense is innate immunity, which includes physical and chemical barriers. The second line is non-specific resistance, which is made up of non-specific innate responses. Finally, we have acquired immunity, which is a specific adaptive response. In this video, we'll explore each of these levels of defense, and provide real-world examples to help you understand them better.
