Final answer:
Inflammation is characterized by redness, swelling, warmth, pain, and loss of function, which are part of the body's immune response to injury or infection.
Step-by-step explanation:
The signs of inflammation include redness, swelling, warmth, pain, and often loss of function. These symptoms occur due to innate immune responses that increase blood flow to the affected area and are crucial for fighting off pathogens and starting the healing process.
Inflammation can be triggered by infection or tissue injury, with the immune system activating to limit and repair the damage. If inflammation persists, it can become chronic and contribute to diseases such as arthritis or tuberculosis.
