Answer 1

Answer:

Inflammation

Explanation:

The inflammatory response (inflammation) can be described as a localized response to an injury or to the destruction of tissues. It occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The cells in  damaged tissue release chemicals that can cause swelling, redness, heat, pain in the damaged area, all as part of the healing process. Some of those chemicals are cytokines that bring in body's immune cells. Others are histamine and prostaglandins which cause swelling, pain and fever. As the body heals, the inflammation gradually decreases.
