In other words, opsonation is a way for the immune system to label and target pathogens for elimination, allowing the body to fight off infections more effectively. The prefix "opsos" comes from Greek, meaning "food" or "nourishment", highlighting the way opsonins provide a "food" for immune cells to feast on unwanted pathogens.
