Which statement about inflammation is true?

• A. Inflammation is not involved in healing after cellular injury.
• B. Inflammation cures tissue damage without healing.
• C. Inflammation occurs before any injury.
• D. Inflammation is a common response to cellular injury and is part of the healing process.

Answer: (D)

Inflammation is the body's immediate protective response to tissue injury and a crucial part of the healing process. When damage occurs, blood vessels dilate and become more permeable, allowing immune cells to flood into the area. Neutrophils and macrophages work to remove debris and potential pathogens, while cytokines and growth factors signal the start of repair and tissue regeneration. This coordinated response creates the right environment for healing to proceed, whether by regeneration of normal tissue or formation of scar tissue when needed. That’s why inflammation is a common, active part of healing after injury. Statements that claim inflammation isn’t involved in healing, that it cures damage without healing, or that it occurs before any injury don’t fit the biology of how inflammation works.
