Which of the following immune cells is directly involved in the process of phagocytosis? A) Monocytes B) Eosinophils C) Macrophages D) Neutrophils
Understand the Problem
The question is asking about the types of immune cells that participate in the process of phagocytosis. It provides multiple-choice options and expects the identification of cells that can engulf pathogens or debris.
Answer
Neutrophils and Macrophages
Both Neutrophils and Macrophages are directly involved in phagocytosis.
Answer for screen readers
Both Neutrophils and Macrophages are directly involved in phagocytosis.
More Information
Phagocytosis is a crucial part of the immune response where cells ingest harmful particles or pathogens. Neutrophils are often the first responders in the blood, while macrophages act in tissues. Both perform crucial roles in innate immunity.
Tips
A common mistake is assuming only one type of cell is involved in phagocytosis, but both neutrophils and macrophages are principal phagocytes.
