PATHOLOGY

Detailed explanation-1: -The inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The damaged cells release chemicals including histamine, bradykinin, and prostaglandins. These chemicals cause blood vessels to leak fluid into the tissues, causing swelling.

Detailed explanation-2: -In general, inflammation refers to a condition in the body when it is trying to react to a localized injury of tissues. Signs of inflammation include some or all of the following: redness, heat, swelling, pain.

Detailed explanation-3: -Listen to pronunciation. (IN-fluh-MAY-shun) A normal part of the body’s response to injury or infection. Inflammation occurs when the body releases chemicals that trigger an immune response to fight off infection or heal damaged tissue.

Detailed explanation-4: -Immediately following an injury, the traumatized area becomes red, warm, and painful, and it begins to swell. The swelling process, also known as edema, is the result of acute inflammation, a response triggered by damage to living tissues.

Detailed explanation-5: -Bradykinin, a major plasma protease present during inflammation, increases vessel permeability and stimulates nerve endings to cause pain.
