What do antibodies do to pathogens?

Explanation:
Antibodies work by recognizing specific features (antigens) on pathogens and binding to them. This binding can neutralize the invader by blocking its ability to attach to host cells and by neutralizing toxins it may produce. It also causes pathogens to clump together (agglutination), which makes it easier for immune cells to spot and ingest them in a process called phagocytosis. Antibodies don’t usually kill pathogens directly or create a physical barrier around them, and they neutralize toxins by binding to them rather than dissolving them.
