MICROANATOMY

Detailed explanation-1: -An inflammatory response begins when a pathogen stimulates an increase in blood flow to the infected area. Blood vessels in that area expand, and white blood cells leak from the vessels to invade the infected tissue. These white blood cells, called phagocytes engulf and destroy bacteria.

Detailed explanation-2: -The second line of defense of the innate system includes chemical signals that produce inflammation and fever responses as well as mobilizing protective cells and other chemical defenses. The adaptive immune system mounts a highly specific response to substances and organisms that do not belong in the body.

Detailed explanation-3: -First line of defense: Owns and manages risks/risk owners/managers. Second line of defense: Oversees risks/risk control and compliance. Third line of defense: Provides independent assurance/risk assurance.
