Verified step by step guidance1
Step 1: Understand the function of leukocytes (white blood cells) in the immune system. Leukocytes protect the body by identifying and eliminating pathogens such as bacteria, viruses, and debris.
Step 2: Review the main types of leukocytes and their primary functions: Neutrophils, Basophils, Eosinophils, Lymphocytes (including plasma cells), and Monocytes.
Step 3: Identify which leukocytes are primarily phagocytic. Phagocytosis is the process of engulfing and digesting pathogens and cellular debris.
Step 4: Recognize that neutrophils are the most abundant type of phagocytic leukocytes and are the first responders to microbial infection, actively engulfing and destroying pathogens.
Step 5: Confirm that erythrocytes (red blood cells) do not have immune functions, plasma cells produce antibodies but are not phagocytic, and basophils are involved in inflammatory responses but not primarily phagocytic.
