Introduction to Innate Immunity

This video tutorial introduces the immune system, focusing on the innate immune system. It explains how the innate immune system is an ancient defense mechanism, distinct from the adaptive immune system, and highlights its key features such as barrier defenses, the complement system, and inflammation. The tutorial emphasizes the importance and complexity of innate immunity, despite its evolutionary conservation across species.

Describe the role of the complement system in the innate immune response.
