Question: 1 / 400

During the inflammatory phase of full-thickness wound healing, which cell arrives first to kill bacteria?

Macrophage

Eosinophil

Neutrophil

During the inflammatory phase of full-thickness wound healing, neutrophils are the first responders to the site of injury. These white blood cells play a critical role in the body’s immune response by quickly arriving at the wound site and acting to eliminate bacteria and other pathogens, thus helping to prevent infection.

Neutrophils achieve this through a variety of mechanisms, including phagocytosis, where they engulf and digest foreign invaders, and the release of reactive oxygen species that can kill bacteria. The swift arrival and action of neutrophils are essential for managing any potential microbial threats that could complicate the healing process.

Understanding the role of neutrophils helps clarify why they are the first type of immune cell to respond during the inflammatory phase of wound healing, setting the stage for subsequent actions by other immune cells and the overall healing progression.
