What role does inflammation play in cellular injury?

• A. It delays recovery indefinitely
• B. It reduces blood flow
• C. It is one of the first steps to healing.
• D. It causes immediate cell death

Answer: (B)

Inflammation is the body's early protective response to injury, aimed at containing damage, clearing debris, and setting the stage for repair. It triggers vascular changes that bring more blood and immune cells to the site: arteries dilate to increase blood flow, causing warmth and redness, while capillaries become leaky to let fluids and immune cells into the tissue. Neutrophils arrive first to engulf invaders and dead cells, followed by macrophages that continue cleanup and release signals to recruit more repair processes. Because of this, inflammation supports healing rather than harming it. It does not reduce blood flow; it increases it to deliver immune effectors and nutrients needed for recovery. It does not cause immediate cell death as its primary role; rather, inflammation helps prevent further injury and accelerates repair. In acute injury, inflammation is one of the first steps toward healing.
