Question

Quizplus · Accepted Answer

Complement can be activated by both the specific and non-specific immune systems. The non-specific activation is usually triggered by the presence of foreign material, such as bacteria or viruses, and can initiate the complement cascade. The specific activation is triggered by binding of antigen-antibody complexes to complement proteins, which leads to the activation of the complement system.
