Which option lists the full eight phases of injury as stated in the material?

• A. Primary Injury, Ultrastructural Changes, Chemical Mediation, Hemodynamic Changes, Metabolic Changes, Permeability Changes, Leukocyte Migration, Phagocytosis
• B. Primary Injury, Edema, Infection, Healing
• C. Inflammation and Repair
• D. Primary Injury, Inflammation, Edema, Healing

Answer: (A)

The main idea here is recognizing the eight-part sequence used in the material to describe the injury response, from the moment of impact through the early inflammatory processes and cleanup. The full eight phases are: Primary Injury, Ultrastructural Changes, Chemical Mediation, Hemodynamic Changes, Metabolic Changes, Permeability Changes, Leukocyte Migration, and Phagocytosis. Immediately after injury, tissue damage occurs—that’s the Primary Injury. The next phase looks at what happens at a cellular level, reflected by Ultrastructural Changes. Chemical mediators are released to coordinate the response, known as Chemical Mediation. Blood flow and vessel behavior shift in the area, described as Hemodynamic Changes, followed by Metabolic Changes that reflect altered energy use and substrate needs. Permeability Changes explain why fluids and cells move out of vessels, contributing to swelling. Leukocyte Migration covers the recruitment of immune cells to the site, and Phagocytosis is the cleanup phase where debris is removed and healing begins. This eight-item sequence provides a detailed, step-by-step view of the injury response that the material presents, making it more complete than the other options. The other choices either condense the process into fewer stages or group things under broader labels like inflammation and repair, which don’t capture the eight distinct phases described.
