Verified step by step guidance

Understand the definition of inflammation: Inflammation is a biological response to harmful stimuli such as pathogens, damaged cells, or irritants, and it is a protective mechanism involving immune cells, blood vessels, and molecular mediators.

Identify the common signs of inflammation: These include redness, heat, swelling, and pain, which are due to increased blood flow and immune cell activity in the affected area.

Recognize the purpose of inflammation: It aims to eliminate the initial cause of cell injury, clear out necrotic cells and tissues damaged from the original insult and the inflammatory process, and establish a repair process.

Evaluate the statement about permanent tissue damage: Inflammation does not always result in permanent tissue damage. While chronic inflammation can lead to tissue damage, acute inflammation is often resolved without permanent damage.

Conclude which statement is not true: Based on the understanding that inflammation does not always result in permanent tissue damage, identify that the statement 'Inflammation always results in permanent tissue damage' is not true.
