What role do neutrophils play in the immune response?

Neutrophils are a type of white blood cell that play a crucial role in the immune response, particularly during the early stages of infection. Their primary function is to ingest and eliminate pathogens, such as bacteria and fungi, through a process known as phagocytosis. When an infection occurs, neutrophils are often among the first immune cells to arrive at the site, where they engulf and digest microorganisms. This action is vital for controlling infections and preventing the spread of pathogens within the body.

While other options describe important immune functions carried out by different cell types or mechanisms, neutrophils are specifically specialized for the ingestion of bacteria and fungi, making this response particularly accurate in the context of their role in the immune system.
