Final answer:
After a skin injury like abrasions from a fall, the body's first response following clot formation is the inflammatory phase. This leads to increased blood flow and swelling, followed by fibroblasts initiating tissue repair through collagen deposition. The process of wound healing can proceed by secondary or primary intention, depending on the size and type of the wound.
Step-by-step explanation:
Physiologic Phenomenon After a Skin Injury
Following a skin injury such as a motorcycle fall with abrasions, the client's body will begin the wound-healing response. The first physiological phenomenon that occurs after the formation of a blood clot is the initiation of the inflammatory response, which includes increased blood flow, warmth, swelling, and pain at the site of the injury. This leads to the inflammatory cells and fibroblasts starting the process of tissue repair by removing waste products and depositing new collagen.
These stages of healing continue with the formation of new blood vessels, or angiogenesis, leading to the development of granulation tissue. The wound edges start to pull together through contraction, and with larger wounds, healing occurs by secondary intention where the area is refilled with cells and collagen over time until the wound is closed. In contrast, smaller wounds with closely opposed edges may heal by primary intention, often with less scarring and more rapid healing.
