Final answer:
The correct order of events in the inflammatory response immediately after tissue injury is d. 3, 2, 5, 1, 4.
Step-by-step explanation:
The correct order of events in the inflammatory response immediately after tissue injury is d. 3, 2, 5, 1, 4.
First, after a skin injury, the body initiates a wound-healing response which includes the formation of a blood clot to stop bleeding (Step 3). This is followed by an increase in vascular permeability, causing redness and swelling (Step 2). Next, white blood cells seep into the injured area, releasing inflammatory chemicals, causing pain and swelling (Step 5). The fourth step is the release of mast cell granules and potent inflammatory mediators, causing vasodilation and fluid leakage in the surrounding tissue (Step 1). Finally, in the last step, the repair phase begins, which includes blood clotting and the regeneration of tissue as fibroblasts deposit collagen (Step 4).
The correct order of events in the inflammatory response immediately after tissue injury is as follows: First, tissue injury occurs, releasing the contents of injured cells. Next, inflammatory chemicals such as histamine, leukotrienes, and prostaglandins are released. This causes vasodilation, leading to increased blood flow, which is responsible for the redness and heat. The increased permeability of blood vessels allows for fluid leakage, causing swelling. These events are followed by the migration of white blood cells into the injured area to seep out the infection or debris, playing a critical role in wound healing. Finally, the repair phase includes blood clot formation to stop bleeding, and deposition of collagen fibers by fibroblasts to regenerate tissue.
