What is the first phase of tissue healing?

• A. Inflammation phase (0-36 hours)
• B. Proliferation phase
• C. Ice to slow down swelling
• D. Remodeling phase

Answer: (A)

The first phase of tissue healing is inflammation. This initial response starts immediately after injury and typically lasts up to about 36 hours. It involves stopping the bleeding by forming a clot and sending immune cells to the area to clean up debris and fight potential infection. Chemical signals increase blood flow and permeability, bringing nutrients and cells needed for repair. You’ll often see redness, warmth, swelling, and pain as part of this process. The purpose is to contain injury and set the stage for repair, creating an environment where tissue can begin to rebuild.

After this comes the proliferation phase, where new tissue and blood vessels form, and then the remodeling phase later, where the tissue is reorganized and strengthened. An ice application isn’t a phase of healing itself; it’s a method to manage swelling and pain during the acute period.
