Final answer:
Inflammation is the body's response to injury or infection, triggered by chemicals released by injured cells. Histamine, leukotrienes, and prostaglandins are examples of inflammatory chemicals that play specific roles in the process.
Step-by-step explanation:
Inflammation is the body's response to injury or infection. It is triggered by chemicals such as cytokines and histamines, which are released by injured or infected cells or immune system cells. These chemicals cause capillaries to dilate and become leaky, increasing blood flow to the area and allowing immune cells to enter the tissues. Some inflammatory chemicals include histamine, leukotrienes, and prostaglandins, which play specific roles in the inflammatory process.
