Verified step by step guidance1
Understand the role of phagocytic cells: Phagocytic cells are a type of immune cell that engulfs and digests cellular debris, foreign substances, microbes, and cancer cells. They are an essential part of the body's defense mechanism.
Identify the types of phagocytic cells: The main phagocytic cells in the human body include neutrophils, macrophages, and dendritic cells. These cells are part of the innate immune system.
Evaluate the options given: Eosinophils, basophils, and T cells are also part of the immune system but have different functions. Eosinophils are involved in combating multicellular parasites and certain infections. Basophils release histamine during allergic reactions. T cells are part of the adaptive immune system and are not phagocytic.
Focus on neutrophils: Neutrophils are the most abundant type of white blood cells and are the first responders to microbial infection. They are highly phagocytic and play a crucial role in the innate immune response.
Conclude with the correct answer: Based on the understanding of phagocytic cells and the options provided, neutrophils are the correct answer as they are the primary phagocytic cells in the human body.
