Question

What are the inflammatory chemicals?

Answer 1

Mast cells, platelets, and basophils produce the vasoactive amines serotonin and histamine. Histamine causes arteriolar dilation, increased capillary permeability, contraction of nonvascular smooth muscle, and eosinophil chemotaxis and can stimulate nociceptors responsible for the pain response.

Answer 2

Step-by-step explanation:

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.
