Questions & Step-by-Step Solutions

What is the primary function of the complement system in the immune response?
  • Step 1: Understand that the complement system is a part of the immune system.
  • Step 2: Know that its main job is to help the body fight off infections.
  • Step 3: Learn that it does this by marking pathogens (like bacteria) for destruction, a process called opsonization.
  • Step 4: Realize that the complement system can also directly attack and destroy pathogens by forming a structure called the membrane attack complex.
  • Step 5: Conclude that the complement system enhances the immune response by both marking pathogens and directly killing them.
