Verified step by step guidance

Understand the context: The problem is asking about a specific process involving neutrophils, which are a type of white blood cell, during inflammation.

Identify the key terms: The options provided are 'Opsonization', 'Phagocytosis', 'Diapedesis', and 'Chemotaxis'. Each term describes a different process related to immune response.

Define 'Diapedesis': This term refers to the movement of neutrophils out of the bloodstream and into the tissues. It is a crucial step in the inflammatory response where neutrophils migrate through the endothelial cells of blood vessels to reach the site of infection or injury.

Differentiate the terms: 'Opsonization' is the process where pathogens are marked for destruction by phagocytes. 'Phagocytosis' is the engulfing and digestion of pathogens by cells like neutrophils. 'Chemotaxis' is the movement of cells towards chemical signals, often towards the site of infection.

Conclude the correct term: Based on the definitions, 'Diapedesis' is the term that specifically describes the migration of neutrophils from blood vessels during inflammation.
