Detailed explanation-1: -Inflammation. The body’s second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation.
Detailed explanation-2: -The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
Detailed explanation-3: -Inflammation acts as a second line of defense when tissue is damaged. Inflammation is triggered by chemicals called cytokines and histamines, which are released when tissues are damaged. These chemicals cause local blood vessels to dilate, which increases blood flow to the area.
Detailed explanation-4: -It is now recognized that inflammation induced by microbial infection and tissue damage is an essential mechanism of innate immune response. Proper inflammatory responses provide broad spectrum protection against infections and orchestrate long-term adaptive immunity toward specific pathogens.
