During hemostasis and inflammation, what is the main event occurring?

• A. WBC flowing into injury site
• B. Platelets forming a plug
• C. Fibroblasts laying down collagen
• D. New skin forms over wound

Answer: (A)

The main event being tested is the influx of white blood cells to the injury site. Inflammation centers on leukocyte recruitment to defend against infection, clear debris, and set the stage for healing. Chemotactic signals draw neutrophils first and then other immune cells into the damaged tissue, coordinating the inflammatory response. Platelets forming a plug is the primary action of hemostasis, which stops bleeding but is not the defining feature of inflammation. Fibroblasts laying down collagen and new skin formation occur later in the repair process—fibroblast activity is part of tissue rebuilding, and epithelialization (new skin formation) happens after the inflammatory phase to restore the surface barrier.
