Verified step by step guidance

Understand that inflammation is a complex biological response to harmful stimuli, such as pathogens, damaged cells, or irritants.

Recognize that the inflammation process is initiated by tissue injury, which leads to the release of chemical signals.

Identify that these chemical signals include histamines, cytokines, and other mediators that play a role in the inflammatory response.

Acknowledge that the release of these chemical signals is the first step in the inflammation process, setting the stage for subsequent events like increased vascular permeability, vasodilation, and leukocyte migration.

Consider how these initial chemical signals lead to the recruitment of immune cells to the site of injury, facilitating the healing process.
