Question

Which phase of wound healing begins within minutes of an injury?

1) Inflammatory phase
2) Proliferative phase
3) Remodeling phase
4) Epithelialization phase

Answer 1

The Inflammatory phase of wound healing begins within minutes of an injury, leading to blood clot formation and the initiation of the healing process.

Step-by-step explanation:

The phase of wound healing that begins within minutes of an injury is the Inflammatory phase. This phase is characterized by the classic response of the body to injury, where the area becomes red, feels warm, swells, and is painful. Various cells like injured cells and resident macrophages release chemical signals that lead to vasodilation and fluid leakage in the tissue around the injury. The Inflammatory phase leads to the formation of a blood clot, which is crucial for stopping blood flow, followed by a scab that forms over the clot.
