Introduction to Immunology Biology Diagrams The immune response is the body's ability to stay safe by protecting against harmful agents. The response involves lines of defense against most microbes and specialized and highly specific responses to particular offenders. This immune response is either innate, nonspecific, adaptive acquired, or highly specific. The innate response, often our first defense against anything foreign, defends Courses on Khan Academy are always 100% free.

Inflammation is a common pathogenesis of many chronic diseases, including cardiovascular and bowel diseases, diabetes, arthritis, and cancer [ 9 ].
The inflammatory response is a localised defence mechanism used by the body following a physical injury or infection. In response to injury and infection, specialised immune cells called mast The inflammatory response consists of four key steps: tissue damage and infection, release of inflammatory mediators, vasodilation, and removal of invading microbes.Initially, tissue damage allows pathogens to enter, triggering mast cells to release cytokines like histamine, promoting inflammation.Vasodilation increases blood vessel permeability, facilitating immune cell migration (diapedesis The process of inflammation has three stages: vasodilation and increased vascular permeability, emigration of phagocytes from the blood to the tissue, and; tissue repair. The stimuli that could trigger inflammation include burns, chemical exposure, heat, cold, or trauma. Regardless of why it starts, the inflammatory response is always the same.

Inflammation is an essential aspect of the innate defense mechanism of the body against infectious or noninfectious etiologies. This mechanism is nonspecific and immediate.[1] The 5 fundamental signs of inflammation include heat, redness, swelling, pain, and loss of function. Increased blood flow leads to redness and heat, while swelling results from fluid accumulation.
