Inflammation is in response to the release of histamine from mast cells. Have you ever noticed how your skin gets red, swollen, and hot when you get hurt, and how sometimes a wound is sensitive to touch?
The purpose of inflammation is to protect the damaged tissue or site of infection, to promote healing, and clear/prevent further infection.
- Inflammation causes an increase blood flow to a damaged area or site of infection, to get more blood to the site of infection to deliver nutrients and to clear off any waste materials.
- There is an increase in capillary permeability to make it easier for immune cells to go to the site of infection and fight off any pathogens.
- The temperature of the infection site is increased to deliver more energy to the cells that need to heal, making the area hot to the touch.
- Inflammation could trigger the activation of complement to assist in killing off pathogens.
