Inflammation

Definition

Inflammation is the body's natural response to injury or infection, where the immune system sends cells to heal damaged tissue and fight off invaders like bacteria and viruses.

Scientific / Technical Definition

Inflammation is a complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. It is a protective reaction involving immune cells, blood vessels, and molecular mediators designed to eliminate the initial cause of cell injury, clear out necrotic cells and tissues, and establish tissue repair.

Benefits

• Inflammation can help the body heal by removing harmful stimuli.
• It is essential for defending the body against infections.
• Creates a healing environment necessary for tissue repair.

Examples

• Redness and swelling after a skin injury.
• Sore throat due to infection causing inflammation.

Additional Information

• Effects: While short-term inflammation is beneficial, chronic inflammation can contribute to various diseases such as arthritis, heart disease, and diabetes.
