Explanation:
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: -Inflammation occurs in response to physical trauma, intense heat and irritating chemicals, as well as to infection by viruses and bacteria. The inflammatory response: (1) prevents the spread of damaging agents to nearby tissues (2) disposes of cell debris and pathogens and (3) sets the stage for the repair process.
