Question

Quizplus · Accepted Answer

Antibodies are proteins produced by B cells that have several functions, including activating the complement system, inactivating pathogens by binding to them and preventing them from infecting cells, and clumping pathogens into larger structures that are easier for the immune system to eliminate. Antibodies can also mark pathogens for destruction by other immune cells, such as macrophages. However, they do not directly cause a warm and swollen response or cause B cells to clump with T cells.
