Verified step by step guidance
1
Understand the role of macrophages and neutrophils in the immune system. Both are types of white blood cells that play a crucial role in the body's defense against infections.
Recognize that both macrophages and neutrophils are part of the innate immune system, which provides a non-specific defense mechanism against pathogens.
Learn that phagocytosis is a process where cells, like macrophages and neutrophils, engulf and digest pathogens and debris. This is a key function they share.
Differentiate between the options given: punching holes in membranes, secreting lysozyme, stimulating antibody production, and attacking virus-infected cells. These are not primary functions shared by both cell types.
Conclude that the common function of macrophages and neutrophils is phagocytosis, where they ingest and break down pathogens, thus protecting the body from infections.
