What induces the inflammatory response? What are the characteristic features of this response?

Five classic signs of inflammation are as follows:

warmth, redness, swelling, pain, and fever

Now let's dissect each symptom and clarify the underlying cause:

The three characteristics of inflammation—redness, warmth, and swelling—can all be attributed to the same process: blood leaking from the circulation into the injured or infected tissues. Bradykinin, prostaglandins, and histamine—the most significant inducer—all play a role in this process by causing arteriolar vasodilation and capillary leakage, which in turn results in the fresh, warm blood leaking into the interstitial area, contributing to the swelling, warmth, and redness that are characteristic of inflammation.

Two chemicals that increase the sensitivity of nerve receptors in the surrounding tissue are responsible for the perception of pain: prostaglandin E and bradykinin.

And lastly, fever is the outcome of a fairly intricate systemic process that is irrelevant here. Just know that an important component of this process is a cytokine called interleukin-1, which causes the brain to elevate the body's temperature, leading to fever.

I hope this is useful.

The inflammatory response is induced by various factors, including pathogens, physical injury, toxins, and allergens. Characteristic features of the inflammatory response include redness, heat, swelling, pain, and loss of function in the affected area. This response is mediated by immune cells, such as leukocytes and mast cells, and involves the release of inflammatory mediators like cytokines, histamine, and prostaglandins.
