Complement 1 Classical Pathway

The video tutorial explains the complement system, a crucial part of the immune system, focusing on the classical pathway. It details the structure and function of antibodies, the activation of the complement system through antibodies, and the formation of C3 and C5 convertases. The tutorial also covers the role of C4 and C2 in the process and the formation of the membrane attack complex, which ultimately lyses pathogens.
